In computer science, data recovery is an act of recovering inaccessible, lost, corrupt, damaged or formatted data out of secondary storage devices, removable media such as floppy disks, CD-ROMs, DVD disks, and other media, when the actual data still can’t be read in an ordinary manner. This recovery process is carried out by the aid of a special device called a “data recovery machine” or sometimes more interestingly “data retrieval software”. Data recovery is one of the most important and most exploited IT security risks because most data that are lost or deleted are not really lost for good. The damage can be done intentionally or unintentionally. Data recovery is very important in case of deleted or lost data because most computers come with a built-in restore function which allows the user to recover deleted data.

Data recovery also helps to prevent data loss from viruses and hackers who can hack into the computers and retrieve lost information. Recovery helps in recovering important data that has been lost due to any number of reasons such as accidental deletion, file corruption, unintentional or intentional formatting, malicious programs, system crash, and others. Data recovery also helps to restore a system’s lost data after the system has been “purged of all data”.
There are several techniques used for retrieving deleted data from a computer. The technique that is used depends on the extent of the damage. If the data is not too damaged, the simplest technique can be used. A file recovery software program can recover deleted data. File recovery software is a special program that is designed for retrieving deleted data from a computer hard disk or other storage media.
One popular technique used is the “water recovery” technique. A person needs to get back the vital information from a computer that has been infected by a virus, worms, Trojans or even a group of malware. If you have accidentally deleted some files from your disk, then it is good to try to recover them with the help of recovery software. Most recovery software available in the market today to recover data even when the drive is full and almost unusable. The software gets rid of all data on a functional drive and thus makes it easy for you to restore lost information.
Data recovery for corrupt or damaged devices is not easy at all. It is not as easy as recovering information from a logical drive. It is more difficult because most of the time, computer systems encounter data loss due to bad sectors on the disk or due to physical damage to the device. Physical damage could be due to any reason like a failure in the hard disk or due to a virus attack. To recover data from physical damage, you need to troubleshoot the problem first and then try to recover data from another drive using a different operating system.
You can also use backup software to copy the recovered data to another storage media like a CD, DVD or an external hard drive. There are many software available in the market that can help you in this task. But the best way to back up your data is to use a raid system in your storage media and in the same manner copy the recovered data on it. If the backup is complete and the storage media is functioning, then transfer the data over the network using an FTP.
