Introduction
Data is defined as groups of information pertaining to quantitative or qualitative attributes. Almost every company today thrives on data for their business plans. Surveys and other methods provide the data to formulate marketing and other plans. Business operations continuously generate data on clients that need to be stored and retrieved for sustenance of business. In the modern era, amazing volumes of data are generated and stored and most often such data management systems are computer driven.
There is almost no doubt whatsoever that data is one of the foundation pillars for any company. This importance can be highlighted by taking the scenario of disruptions in data management systems. Take a look at some of these facts - 60% of companies that lose their data will shut down operations within 6 months of the loss. 93% of companies that lost their data center for even 10 days filed for bankruptcy within one year according to National Archives and Records Administration in Washington. US businesses lose over $ 12 billion per year due to data loss.
Data Recovery
Data loss can happen in many ways in the field of information technology. Such losses cause immense failures for companies too. Data loss is unforeseen and can be cause due to human error, power failures, software corruption, natural disasters and deliberate actions like sabotage or hacking.
A report on data loss in Europe concluded that there are six main causes of data loss. Hardware failure accounts for most damage at 42%, human error at 31%, software corruption at 13%, virus infection at 7%, thefts at 5% and hardware loss at 3%.
Data Storage and Recovery therefore becomes of paramount importance to companies and concerns.
Popular Methods of Data Recovery
Data recovery in most simple terms denotes the process by which files that have been damaged by any of the methods mentioned above are restored, thereby retrieving the data that was once stored on them. The ballpark estimate of average percentage of successful retrievals is in the 80 to 90 % range. Recovery is more often done on storage media like tapes, CDs, DVDs, RAID or redundant array of inexpensive disks, hard disk drives to name a few.
Data recovery services are offered by companies of all kinds and sizes. Typically, these companies will advise a client on the method by which they can send their damaged systems, then follow it up with a price quote and an idea as to how much of that data can be recovered. Most of these companies charge a client only if they have been able to recover the data. Data recovery services
Very broadly speaking, data recovery can be addressed in 2 categories - software recovery and hardware recovery. Hardware recovery denotes the process by which data is recovered from hard drives which may have failed due to faulty circuits or faulty actuator arms. Hard drive recovery needs specialist equipment to read the disks or platters and can be expensive since the technician must disassemble the hard drive to assess and fix the problem. Software recovery occurs due to problems in accessing the data from storage areas. Data recovery software divides all magnetic space on a hard drive into small storage areas known as sectors which hold the contents of the files on the computer.
Hard drive recovery
Hard drive recovery is possible on almost all types of computer systems. Usually hard drives fail due to either a physical crash or a logical crash due to human error. Techniques such as hardware repair and disk imaging can help retrieve data after a physical damage incident. Methods such as consistency checking and data carving help in data recovery after a logical damage incident. Hard drive recovery RAID is now an all encompassing term to cover data storage systems. RAID results in enhancement of data reliability and increase in i/o performance. Basically these data storage systems divide and replicate data among multiple hard disk drives. When such disks use RAID technology, they are said to be in a RAID array. RAID combines a number of hard disks into one logical disk to result in decreasing the occurrence of incidents of data loss, increasing storage space, speeding up RAID data recovery and making systems more flexible. This can be done with specialized hardware or software. To the user, the combined disks will work as one hard disk but operationally speaking, data is stored more often and on occurrence of failure of one disk, other disks on the system take over the function of copying the data. There are different levels of RAID like RAID 0, 1, 2, 3, 4, 5 and 6 and other non standard RAID levels like Double Parity/ DP, 1.5, 5E, 5EE, 6E and 7. RAID can result in increased performance, protection of uptime but cannot simplify disaster recovery and cannot be moved easily to a new system.
Simple ways to prevent data loss
While most data loss incidents happen due to operating system failure, hardware failure, or even human error, a user can take some simple steps to prevent data loss. These steps can include backing up critical files, handling computers and hardware with care, monitoring the health of the diagnostics software, using equipment to guard against power surges, running up to date anti virus software and perhaps the simplest of them all - quitting programs before shutting down the computer.
