The first thing you will need to do is to consult from your friends and relatives who have computers and have had them before. At one time or the other, they have also experienced loss of data. They can be of great help to you. If there is none, you can even ask it on the social media such as Facebook. This is a place where you can easily be directed. You can also use the search engines that are available at your disposal. This can be a good source of information. Once you find one, go through their website carefully, and ensure that it is a registered company first and close to your physical address to avoid too many costs that arise with transportation. Ensure that the data recovery expert is available for you depending on how fast you need your data back. Consider their costs too. This is mainly done through comparison of prices from one company to the other. There are companies, which offer discounts on this service. Ensure you look out for them and benefit from the discounts.

When Do We Need Data Recovery Experts?

expertDespite the attempt of those who are concerned, the digital instruments tend to fail at times. Just like any other man-made instrument, computers face with threats and the danger of losing their vitality. Unlike the past, the modern scientific era has lead to an increased or a common dependency of humans on machines. Reliability on computers regarding the vital issues related to personal affairs, business affairs and all modes of actions and transactions has augmented unbelievably. Parallel to that, the risk factor increases as computers can malfunction without prior notice, giving way to a complete loss of crucial data saved within the diversified drives. For instance, the hard drive may crash, without any premonition displayed causing a total destruction of data. Several internal or external reasons may cause malfunctioning of the drives, endangering the data deposited in. The problems arising would be related to both hardware and software. Sometimes, in a computer network, more than one hard drives can fail, owing to failures in controllers. Sometimes the drives may work, but their intelligence may lack. In most cases, human-errors occur, while individuals lacking expertise try to fix the problems. For instance, a wrong drive may be pulled out instead of the faulty one which would ultimately lead to a scrambling of data. PC users are always advised to keep backups of significant data, but in case of emergency, the assistance of data recovery experts is of paramount importance.

Why You Should Choose A Data Recovery Expert

toolsA data recovery expert has to be a very effective person. Effectiveness is a vital element in data recovery and will determine the amount of data that will be recovered. An effective data recovery expert will also ensure that his work is done on time and delivered within the set deadlines. Another quality that you should consider before choosing a recovery expert is their flexibility. There are moments when you will need your recovery done from your premises. This means that you should choose an expert who can easily agree with your specifications. It is very important for you to choose an expert in this field since they are reliable and knowledgeable in this kind of job. An expert is someone who has taken time to study about the subject matter and you can be sure of good results. They are also well equipped for their work. Lastly, most data recovery experts offer excellent services to their clients. There are some disks, which require special attention that only experts can handle this. This is the moment expertise in this particular field comes in handy. You should not settle for a person who is not an expert in data recovery. Otherwise, you will lose more and more data other than recovering it. From there, you’ll need to compare data recovery prices

Qualities Of A Good Data Recovery Expert

There are a number of qualities that a data recovery expert needs to have. First and foremost, he needs to have the best computer skills. These should include knowledge of the workings of electronics and even the mechanical bit of the ways computers and other devices from which information can be gotten work. This is the area that he will be working on and thus, he needs to understand all these. He also needs to know how data is stored in storage locations. For instance, the specialist needs to understand how the different file systems manage data storage. Digital storage media like USB’s, RAID arrays and even SSD’s all need to be understood by the technician whose main work is to help people get back the important information that they may have lost. Since he will be using a range of tools and equipment, he needs to have all these at his disposal. It is important to note that without these facilities, the knowledge that he has in terms of data recovery may be useless. Hence, he needs to work in place where there is all the necessary equipment that he might need for any kind of recovery work. If not, he will not be able to create virtual images from malfunctioned drives to get back the data from them.

Do you need RAID 10 recovery services for your RAID servers that have gone berserk? There are 2 ways you can go about handling the problem; the right way, or the wrong way that will take time, money, and may not guarantee results. The right way may involve calling in the experts, but there is input needed from you. This input is in ensuring that the RAID server environment is clean, has adequate ventilation, and is secure. RAID servers are quite the beasts when running strong, but can be a handful and more when they break down. When looking to recover the data when multiple disks have crashed, the key thing is to how to handle the data. If your RAID array was helpful when playing Call of Duty, you should consider rebuilding the RAID array from scratch. RAID 10 recovery does not come cheap though, as it requires specialized software and tools that many data recovery companies don’t offer it. So if your computer didn’t have any critical data, it is just better to get new hard drives and rebuild the RAID array. However, if the data was crucial to your company’s daily operations, every minute wasted not calling in a qualified RAID 10 recovery expert just worsens the damage. Finding such a company is easy, and is urgency is crucial, doing a web search will provide more than a few options you can choose.

Comparing RAID 5 And RAID 10

raid-5Speaking of data loss recovery schemes, Raid 10 and Raid 5 are the two important storage schemes. The two schemes differ from each other in terms of performance, data-redundancy, architectural flexibility and amount of hard disk required. These two schemes are preferably used by a large number of users to recover RAID. There are several comparisons that we can make to understand the differences between the two schemes. Some of the common comparisons are mentioned below. The Raid 10 scheme has an edge over RAID 5 scheme when it come performance and data-redundancy. RAID 10 is pretty faster than RAID 5 in the write operation. This is why RAID 10 is usually recommended for systems that require high write performance. Besides, raid 10 arrays are more data-redundant if compared with RAID 5. Hence, RAID 10 arrays are also considered an ideal choice for cases and systems that require high data redundancy. In terms of architectural flexibility, RAID 10 arrays are more flexible than RAID 5. The two schemes also differ from each other when it comes to amount of disk space. The RAID 10 array needs a minimized amount of space on the disk. Meanwhile, you would need to determine configuration parameters if you want to recover RAID 5 or 10.

The Recover RAID Data Process Can Be Quite A Process At Times

In a RAID configuration, the drives are arranged in an array, and mirror each other both physically and logically. The concept is to have numerous instances of the stored data, so that if one drive were to fail, the data can be recovered from the other drives. It is a simple concept really, but a powerful one that many large companies utilize to store their volumes of data. For any business that wishes to provide their customers with a constant connection to the network and data provided, having a RAID server installed is a must. It is cheap and cost effective, and goes a long way to keeping data safe and available. Now, the complexity of the RAID drives makes it preferable to call a professional to recover RAID data in times of trouble. The drive arrangement is complex enough to guarantee safety of data, but it is not foolproof. From time to time, the drives will fail or get damaged, and it is up to the recover
RAID data professionals to handle the problem. The recover RAID data process can be quite a process at times. If the damage is physical, the recovery is done by use of software and special tools. Non-physical damage, on the other hand, requires more time and attention, and will most likely cost a small fortune.

Qualities Of A Good Data Recovery Expert

qualified-professionalData recovery is a very sensitive process and it needs an expert to do it perfectly. The expert that carries out this assignment must have the right qualifications for the job. First, he or she must have gone to study about this subject from a recognized institution. Before settling for one, be careful to go through their profile to confirm. They should also have enough experience in this field. An experienced person is well able to deliver a perfect job for you. A data recovery expert should also be honest with you. It is not possible to recover all of your data all at once. A good data recovery expert should be able to provide you with a percentage of how much they can be able to recover. Them that say they can recover 100% are not honest with you. You should not settle for them since you may end up more disappointed than you expected. They should be available for you. You should be a priority to them and they should treat you with respect. An expert who does not pay attention to your instructions can never deliver quality services to you. Every person would want privacy for his or her data. This means that the data recovery expert should have a workshop that offers high levels of privacy especially with the data that contains vital information for a company or business.

raid-arrayTo lose information from a computer system may be a damning experience. This can be very traumatising in the event that the particular information were to be used in the workplace. Therefore, to have RAID 10 recovery will be a big relief to the person responsible for this kind of information. This will give you the chance to carry on with your work and may even save you a lot of money and unnecessary costs. Another benefit that RAID 10 recovery brings is that you do not have to go over physical locations to get the service done. Right from your remote location, you will be helped to get back the data that may have been lost. This therefore means that you will save time by using a convenient method of data recovery. Since RAID 10 methods of storing data are complex, to find a way that brings back the useful information that may have been stored there is simply a relief. There are people who have lost their data and gone ahead to lose much more. This is because they were cheated out of confidential information and they had those details used against them. Most people are therefore very keen on knowing the safety of their information even as they are being helped to get it back. RAID 10 recovery does this work of keeping your information safe through a raft of measures.

RAID 10 Recovery- Great Techniques To Retrieve Your Vital Data!

RAID 10 is a secure and reliable way to store huge amount of data at less cost. It incorporates several low cost hard disk drives in the form of arrays being controlled by a single controller chip. These hard drives are interlinked in such a way that if one of the disks fails, it might affect the functioning of other disks as well. Thus, it becomes essential to employ RAID 10 recovery techniques in order to retrieve all the important data stored in the RAID 10 system. Fixing these issues might seem to be a challenging task for an amateur. That is why it is recommended to seek professional help when you face RAID 10 failure issues. These professional companies have clean rooms called Class 10, 100 or 1000 which are kept extremely neat and clean. This is required because even a particle of dust might cause RAID disks to fail. Class 10 implies that there are not more than 10 dust particles in the room, similarly it holds valid for Class 100 and 1000. The professionals carry out multi-level testing, analysis and repair of the RAID 10 systems. Thus if you’re facing failure issues with your RAID 10 system, it is essential for an expert to look into it and employ RAID 10 recovery techniques as soon as possible to retrieve lost data.

Essential Facts About RAID 10 Recovery

RAID is an abbreviation used for Redundant Array of Independent Disks. Under this technique, a fault tolerant system is created by combining several inexpensive hard drives through a controller chip. Distribution of data takes place within multiple hard disk drives which leads to increase in the storage capacity, data safety and performance of the drives. RAID systems are available in different levels starting from RAID 0. It goes up to RAID 1, RAID 5, RAID 6, RAID 10 and so on. The complexity goes on increasing according to the increase in the level of the RAID system. Since the pattern of storage of data is complex in RAID 10, it becomes difficult to overcome data loss problems. In order to compete with data loss problems, several RAID 10 recovery techniques have been devised so that your valuable data remains safe.<p>A typical RAID system is composed of several parts. RAID failure can occur due to a problem in any of these parts. How ever, some of the common types of RAID failures are RAID array failure, RAID controller failure, Damaged Strip and Rebuild failure. Getting over RAID 10 failure can prove to be a Herculean task for an amateur. So, it is better to seek help from a professional who is an expert at implementing the various RAID 10 recovery techniques.

The Essence Of Partitioning In RAID 10 Recovery

images-(4)To improve the chances of carefully getting back as much information lost as possible, there are certain factors that are of importance. These include but are not limited to the need for a proper partitioning of the physical disks in the RAID 10 array. Due to the number of disks supported in this kind of system, it goes without say that one may be lost on the exact location that a missing file may have been kept. This therefore calls for a proper way of knowing all the constituent parts; possibly through partitioning. RAID 10 recovery is made much easier when the missing files and their sizes as well as locations are known. When the partitioning is done on one logical disk, it gets much easier to trace missing files. It is therefore much harder when there are a number of disks that are used for the simple that a given piece of information may disappear all at once. Thus when setting up this kind of storage, one has to bear in mind the need for precautions should there be data loss in future. However, the mere fact that there is possibility and a great one at that, to recover lost files is good news to many. Files lost by deletion, physical damage and viral infections are easily recovered.

Many companies are fighting back the rising tide of total cost of ownership with comprehensive network management systems that can manage everything from a central location.

There are many factors to be considered when purchasing and implementing these systems, which range from management framework products, such as Hewlett-Packard Co.’s OpenView, Computer Associates International Inc.’s Unicenter and Tivoli Systems Inc.’s NetView, to sophisticated trouble-reporting systems, such as Tivoli’s TME, to router configuration programs such as Cisco Systems Inc.’s NetSys.

netplanTo gain the greatest benefit from the investment network management systems require, network managers must plan how — and why — they are going to use the system as well as how it will be implemented.

First, what is the network management objective? It might sound obvious, but the key to creating an effective network management system is to determine what the system is supposed to be managing.

Is the objective to determine if the network hardware and the network communications software are operating properly? Is it to monitor traffic on the network to find bottlenecks and performance problems? Is it to analyze usage of the network to determine how it is being used to support applications or to control use by certain types of applications?

A network manager may have a good idea about what type of information would do the most good. For example, if the manager has had problems with slow communications between different locations, a tool that monitors WAN performance or router operation might be of the most use. If e-mail delivery and performance have been an ongoing issue, a tool that monitors e-mail system operation would deliver the most immediate payoff.

Second, what will be done with the information? Don’t catch “feature-itis” when shopping for a system. Many network management systems have been put in place, turned on and then largely ignored because the information provided couldn’t be used properly.

It is essential for the capabilities of a network management system to be matched with a manager’s ability to use the information produced. For example, for a nationwide network of 2,000 users located in 10 field offices, a centralized trouble-ticket management system might be more trouble than it’s worth, because problems have to be fixed locally anyway.

In this scenario, a centralized help desk management system with the capability to take over and remotely control users’ desktops would likely provide greater value than a complex network management system.

Steps to implementation

Implementing a network management system — no matter what type — requires several key steps on the part of the manager.

No. 1: Know thy network. Managing a network without good documentation of network topology is like driving through a foreign country without a map. Anyone trying to make sense of the data from a network management system needs a comprehensive map of the network topology, IP and IPX network addresses, server and gateway locations, router ports, and Internet gateways.

Even if a set of reasonably current network diagrams exists, it’s worth investing in a tool that can discover the network periodically, particularly if there are remote segments that aren’t controlled centrally.

For example, Optimal Networks’ Surveyor is one of a number of programs that query router tables and Address Resolution Protocol caches to determine the IP addresses and identities of networks, servers, routers and even workstations.

It’s a good idea to run the network discovery probe every 90 days, just to maintain a current picture of the network.

No. 2: Set the baseline. It’s important to determine the performance or capabilities of the network today, and then establish the performance thresholds against which to measure that performance

The baseline should consist of a network map and a set of performance measures, such as the amount of traffic carried by each network, users or desktops per network, peak and average percentage of bandwidth used, protocols in use, and applications supported.

Once the network’s current performance levels are understood, the network manager can set targets for maximum network usage levels, network performance and applications traffic. For example, the baseline study may show the network manager that the most widely used Internet application is HTTP, but that the heaviest use of HTTP is for PointCast Inc.’s PointCast Network, which accounts for 10 percent of the HTTP traffic.

To prevent PointCast traffic from overrunning the network, the network manager may set a PointCast threshold of 20 percent of the network’s HTTP traffic.

No. 3: Consider the WAN pipeline. Collecting network monitoring and management data at a central site can throw a lot more data onto what might already be an overloaded WAN.

Thus, part of establishing a network baseline is determining the current load on the network. Be sure to ask the vendors of any network management system under consideration how much additional load the network management system will place on the WAN.

No. 4: Implement in phases. Because it’s easy to become overwhelmed by the amount of data a network management system can provide, the best way to implement network management is to phase in the system’s capabilities.

Network administrators should focus on understanding and using the capabilities that meet their core objectives, ignoring the system’s other capabilities until they fully understand how to make use of each component to accomplish a specific goal for performance, system reliability or user support.

No. 5: Integrate components. It can be difficult to integrate network management systems created from different vendors’ systems, as some components may be “point solutions” that aren’t intended to be part of a higher-level system. For example, a product that monitors an e-mail system may not be intended to be part of a coordinated, higher-level network management system.

However, products such as RMON probes or systems that monitor routers, hubs or switches are designed to integrate with more comprehensive, higher-level network management systems. Although there are few well-established standards for network management systems today, it’s important to look for systems that adhere to current standards, such as SNMP or RMON 2, rather than holding out hope for future integration that may not happen.

No. 6: Keep management informed. Properly implemented and used, a network management system can improve system control, reliability and performance, helping to justify the often substantial investment in hardware, software and people necessary to create the system.

Ask any company if it would be interested in increasing its network efficiency and proactively managing its network, and the answer would be yes. Ask it how much it would be willing to pay for such benefits, and the answer is not as clear.

The cost of adding RMON capabilities to a large network can exceed $100,000, and the benefits are difficult to quantify.

rmondiagramAlthough vendors now offer companies more RMON capabilities than ever, many companies don’t use them. “Most companies still manage their networks in a reactive, rather than a proactive, manner,” said Elizabeth Rainge, an analyst at International Data Corp., in Framingham, Mass.

RMON probes sit on devices or network segments and collect information–such as available bandwidth, the number of retransmissions and which applications generate the most traffic–to help network administrators identify network areas that need a boost in performance.

The problem is that a wide variety of devices can slow network activity. A client workstation’s processor may be unable to keep pace with large file transfers, a LAN segment may have too many users sending information, a server may not have sufficient processing power to keep up with transaction loads or a frame relay line may drop packets when users transmit video files.

To pinpoint a problem, a company must deploy RMON probes at each potential trouble spot. LAN probes can cost as little as $1,500, but frame relay probes can cost $10,000 or more. Thus, a large organization with hundreds of LANs can quickly spend $100,000 to outfit its network.

RMON costs don’t end with probes, either. Running a probe consumes processing resources on each device, so a company may have to upgrade switches or computers.

Companies must also purchase a management tool, which costs $10,000 to $100,000. The tool transforms the information RMON probes collect into reports and graphs that illustrate network performance. Depending on how much data is to be collected and how often it is used, the reporting tool may require its own PC or workstation.

Last, the corporation has to train its staff to use the probes and management software. With competition for skilled networking personnel increasing, pay for such personnel is rising.

Many small and medium-size companies opt for the less expensive alternative of spending a few thousand dollars for a protocol analyzer. When response-time issues arise, they remove the analyzer, place it on the network and determine the source of the problem.

This option is not as appealing for large companies. Each time a problem arose, a company would have to send a technician to numerous locations, collect a mountain of performance data and then analyze it.

Cost-justifying RMON

Vendors claim the savings from more efficient network design make RMON worthwhile. “To ensure adequate response time, many companies overbuild their networks,” said Ivan Shefrin, president of Response Networks Inc., an Alexandria, Va., supplier of service-level agreement software.

For instance, a company may identify 10 network segments that could be creating bottlenecks. Rather than use RMON tools to discover that six are overloaded, a company might simply upgrade all 10.

How many organizations have overconstructed their networks is difficult to determine, but one RMON customer has been able to avert major network upgrades. Arizona State University, in Tempe, relies on 20,000 Ethernet connections to support its 49,000 students and 12,000 faculty and staff.

The university decided that monitoring its network was important and purchased Concord Communications Inc.’s Network Health. Now, despite a large number of connections, the university has a modest network infrastructure: Shared 10M-bps connections to users’ desktops feed into an FDDI backbone.

Joseph Askins, the university’s director of data communications, said Network Health has enabled ASU to gradually upgrade select network segments, rather than completely overhaul the infrastructure whenever response-time problems arose. “By placing Ethernet switches in front of a few of our FDDI connections, we have been able to stay away from moving to a higher speed infrastructure like ATM,” Askins explained.

Avoiding application brownouts

Application availability is another major factor in justifying the cost of RMON. “Corporations want to avoid application brownouts–periods of time when they are not available to employees,” said Shefrin of Response Networks.

But determining how much bandwidth and computing power are needed to keep applications running is difficult. When mainframes were widely used, it was easy to gauge network usage patterns because users had limited options. Now, something as simple as workers attaching video clips to e-mail messages can create network slowdowns.

In addition, IT departments can no longer tightly control applications running on corporate networks. With the widespread emergence of department-developed and shrink-wrapped software, end users have more control and can add new applications without warning.

These problems were the driving force behind the development of RMON2. The first version of the standard could examine only bulk network bandwidth; the second iteration breaks down transmission load by application.

This allows companies to identify users who spend a lot of time downloading large files from the Internet and either give them more bandwidth or instructions not to download large files.

RMON2 probes have slowly been making their way to market. “RMON2 is now in the early adoption phase and will become more common during the next few years,” predicted IDC’s Rainge.

Suppliers are also trying to make RMON purchases less costly by developing probes that can be used on multiple network segments. Rather than spending $1,500 to monitor half a dozen LANs, a company can purchase one probe and use it on all six.

Users would like RMON capabilities incorporated in all of their network devices, simply turning them on when they wanted to use them. Although many vendors include some RMON functions in their switches, most have avoided including all capabilities.

“Embedding RMON in a switch increases a company’s product development time,” said Craig Easley, Optivity product line marketing manager at Bay Networks Inc., in Santa Clara, Calif. “Competition is so fierce and product life cycles so short that vendors prefer to get their products to market quicker than [waiting] to include RMON in them.”

Thus, companies must continue to balance the amount of monitoring they’d like to perform against the amount they can cost-justify.

To have great security, you need to assemble an elite group of security experts – what we call a patch patrol — to locate, test, and install software patches in any system that may have a weakness. Don’t treat this as drudge work and assign your least capable programmers to the task. They will not be able to do the job. Fund this team adequately and give them the tools they need to succeed.

net-secNow set your patch patrol in motion. They should begin by checking the vast array of independent and vendor-supported security Web sites, newsgroups, and mailing lists that have sprung up in recent years. Continuous monitoring of these sites will not only help educate your team and improve their skills, it will also provide an early warning of new and dangerous hacker exploits. Monitoring vendor Web sites is important because most vendors are not anxious to publicize their newest security patches since this reflects poorly on their products. You must be proactive in seeking such information.

Next, your patch patrol should conduct a top-to-bottom audit of your networked IT assets — software applications, operating systems, computer systems, routers, modems, the whole bit. With this inventory in hand it’s a fairly easy process to contact each vendor and secure the patches, service packs, and hot fixes that have been issued for each system. Pay particular attention to version control. Different versions of the same software may have different vulnerabilities — requiring different patches.

Your next step involves risk management and triage. Most companies have so many security holes they have no hope of patching them all in a timely manner. Your patch patrol should not waste precious time securing low-value targets. Focus on your mission-critical systems first. In the case of legacy systems, consider retiring those that are no longer supported by your vendor. They make inviting targets.

Okay, now you’re ready to install those patches. But wait. You may violate maintenance agreements with some vendors if you install untested patches. It’s time to bring in the lawyers. They can negotiate an addendum that allows you to secure your network. However, this may require you to establish a test facility to vet some hot fixes and patches. Vendors test their service packs, but there’s no time for them to test a hot fix they developed over the weekend to plug a newly exploited security hole. You need to have this capability in-house.

Once you’ve tested the patches you can go ahead and install them. A veteran patch patrol will know to adjust default settings, make file permission changes, and do all the little things that determine whether a patch functions correctly or not. Unfortunately, many companies earn a failing grade when it comes to installation. Hackers probe for such process breakdowns and invariably find them.

Finally, put pressure on your suppliers to develop more secure software and more timely hot fixes. Tell them this is part of your purchasing criteria. Many vendors still view software security as a cost center and don’t invest the time or money needed to build bulletproof products. The more often you raise this issue, the more likely they are to respond, and the more quickly your software security will improve.

If you are running a company that has got some permanent data needs then it is always better to hire a data recovery company permanently. Some people think that data recovery company is not relevant to their business but when you start depending too much on your data sources then it is better to keep in touch with a recovery company. The work of this recovery company will not be very wide but it will just maintain your data sources. Periodic checks and backup of critical data will be the main task of that company and these small precautions can save you from a big data loss. Budget is another issue that lots of people are concerned about but this kind of permanent hiring will not cost you much. You just have to pay monthly fee to this company and they will take care of all your data resources. This small expanse is lot better than the one time big investment that you will have to do in case of a data failure. Proper maintenance will make your data resources secure and more long lasting. There are many companies that provide maintenance services in very affordable price.

Features To Look For

Servers getting pinched???

Servers getting pinched???

If you are looking to hire a data recovery company like Irvine, CA’s Hard Drive Recovery Group then there are some specific features that you should check in advance. First of all make sure that they are qualified and skilled enough to deal with your data system. Most of the modern companies have very sophisticated data systems installed and these data systems cannot be understood by rookie professionals. Always make sure that they have experienced engineers to deal with all kinds of problems that your data system is facing. Secondly you can look at the price of their services. Though some companies will not bother about the price when their critical data is at stake but still you should be able to work within a limited budget. Another very important aspect is their capability to deal with software and hardware issues. Some companies do not tell you their capability but on the inside they do not have professionals to deal with either software or hardware issues and they will check your data system for only one type of errors. Make sure that your data recovery company has both kinds of experts that cannot only deal with software issues but they should be capable of handling hardware issues as well.

When it comes to choosing the best data recovery company then there are certain features that must be present in that company. First of all you should analyze all of the possible services that they can provide. Local companies must be preferred because these companies are easier to access and they will also provide you better services than other foreign or non-local companies. Another important thing is qualification of their experts. Make sure that they have not got rookie or part time experts instead they must have certified degrees from some recognized college or university. The company should possess both software experts and hardware experts because both kinds of problems can occur in data systems. If you are hiring a company that deal in software problems only then you will have to search for another company that deal with hardware problems as well because it is not necessary that your data system is going through only software issue. Make sure that company that you choose deal with both software and hardware related issues so that you do not have to search again. Budget must be kept in mind because it is never wise to spend an amount that exceeds the price of that data source.

Server data recovery process is an expensive one. One would by all means want to avoid these costs by trying their best to avoid data loss especially for a server. One best way to avoid data loss is by installing an antivirus and keeps it updated always. Choose an antivirus that is of good quality, not just any which is available. Ensure also that it is a type that is updated each and every day. You should have a backup plan for yourself. A server contains a lot of important information. Therefore, you should be willing to invest in a backup plan as soon as you start using the server.

A server data recovery process is not an easy one. Therefore, you will have to protect your server against power surges. Ensure that you have a UPS installed which will ensure that there is no interruption of power supply at any point during the periods of power failure. Another habit that you should always have is the one of cleanliness. Keep your machines in a dry place that is well ventilated and free from dust. It should not also be exposed to too much heat, ensure that you are in an enclosed room. Finally, ensure that you have what it takes to maintain it. If not, seek for assistance from a professional or an expert.


But companies seeking to deliver critical business information over frame relay circuits need a guarantee of network performance for those circuits. Monitoring and controlling the performance and reliability of public-network circuits depends greatly on SLAs (service-level agreements) between companies and service providers and monitoring of the agreements.

SLAs are contracts that define the service levels expected from a service provider and the penalties imposed if the service provider does not comply. These SLAs’ main purpose is to help keep conflicts between companies and service providers to a minimum by setting reasonable expectations of service.

servicesSLAs benefit the client by providing effective grading criteria and protection from poor service. They benefit the service provider by offering a way to ensure that expectations are set correctly and will be judged fairly. Although SLAs include some kind of monetary reimbursement for lost or poor service, that’s a last resort. Ask anyone affected by April’s AT&T frame relay outages — they’d rather have good service than compensation for their lost connectivity.

What does an SLA guarantee?

There are four basic items that should be covered in every SLA: availability, reliability, effective throughput and response time (or delay). Other items to consider include the time it takes to respond to problems and the time required to repair or restore service. Availability is a measurement of how much uptime the customer receives, while reliability refers to how often a network goes down or how long it stays down.

Reliability is a better metric for measuring the consistency of a connection. For example, if a network were to be out of commission 1 minute out of every 10, it would have an availability of 90 percent, but it would be labeled unreliable.

Since the SLA spells out the terms of network performance, both the provider and the customer must accept the same definition for each term. For example, definitions can vary even for a measurement as simple as network availability.

Availability guarantees should include all components of the provider’s network, the local loop to the network and any equipment provided by the service provider (such as a CSU/DSU and router). Service providers may want to exclude the following: a customer-provided CSU/DSU, router or other access device; the local loop when provided by the customer; and network downtime caused by the carrier’s scheduled maintenance, customer-induced outages, dial-in links and natural disasters.

There’s also an important distinction between network-based availability and site-based availability. For a network consisting of 10 sites, a 99.5 percent average network availability would allow 36 total hours of downtime in a 30-day month. If the SLA is based on site availability, any one site can only be down for 3.6 hours in the month. The distinction can be very important when determining compliance with an SLA.

When defining measurements of throughput for an SLA, the traffic load and delay should be measured when the impact is at its highest, which is at times of peak traffic load. Since service providers will often exclude certain transmissions, such as during provider maintenance, from dial-up lines or from new circuits added during a contract month, customers should understand which data has been included in any measurements so that the user’s cross-check measurements will correspond to those performed by the service provider.

Preparing for an SLA

The main step in preparing for an SLA is baselining the network’s performance. This involves monitoring performance over a period of time, usually a minimum of three months, and reviewing the performance data for any trends that may affect network quality. Without this information in hand, a company cannot realistically determine what WAN performance it requires, nor could it tell if performance had degraded or why. This baseline data can also tell a company if it needs to negotiate for special conditions in its SLA.

While an SLA is couched mainly in technical terms such as availability, throughput and response time, there must be a link between these terms and the company’s business needs.

Although network performance is measured by what happens as traffic passes through the devices comprising the WAN, the most important results for the customer are how applications behave and whether users can do their jobs. Proper baselining, therefore, requires tying lower-level measurements made on the network to the business requirements of the enterprise — not a simple matter.

Many service-level management products focus on monitoring service levels with SNMP and RMON and thus do not provide a sufficiently integrated view to let network managers review end-to-end performance for applications.

Some products, such as Hewlett-Packard Co.’s Netmetrix Reporter, Infovista Corp.’s SLA Conformance Manager, Platinum Technology Inc.’s Wiretap, Compuware Corp.’s Ecoscope and Optimal Networks Corp.’s Application Expert, use response times, often with data gathered with SNMP and RMON, to give a more integrated view of network performance.

Monitoring your SLA

Whether a company’s SLA is a standard one provided by the service provider or a custom-negotiated one, it will mean little without a system for monitoring the specified service levels. A good rule of thumb is to review internal measurements of network performance and reliability on a weekly basis and compare them to the service provider’s results every month.

There are also key implementation issues that have a direct impact on the usefulness of SLAs to the network manager. The first issue is where the measurements are taken: end-to-end or just within the service provider’s network (for example, from the provider’s switch at one customer site to another switch at another site). The local loop can have a profound impact on network performance, but it is ignored in a switch-to-switch implementation. Performance measurements (and troubleshooting) should be taken end-to-end.

The second issue is the measurement system — it should be independent of the network being measured and not biased toward switch or router architectures. Also keep in mind that presentation of the information is almost as important as the information itself. As mentioned earlier, integrated display of end-to-end network performance data is still rudimentary.

Many of the service providers offering guaranteed service will locate measurement devices at the customer’s site. For comparison’s sake, users should try to locate their own measuring devices parallel with those installed by the service provider.
