Data recovery is the process in which lost, accidentally deleted or corrupted data is recovered or restored. Data can be restored to a desktop, laptop, server or external storage or drive, typically from a backup. Most data is lost due to inattentiveness or error by man’s part, usually when we delete a file by mistake or send it to the wrong person, when we accidentally format the computer, or when we damage the computer by spilling liquids on it. However, data loss can also happen due to external causes such as viruses, power outages, server malfunction, software crash, or damage in the internal hard drives.
Data recovery processes
There are many data recovery processes. Data recovery can happen if the lost files are backed up or if they are not; however, some recovery procedures sometimes demand the intervention of a specialist of a data recovery technician.
The recovery of files that are not backed up is possible because some of its fragments remain on the hard disk. Data recovery, in general, is possible because the files usually exist in different places, and the actual file to be recovered still exists in the hard drive. If the file is damaged or doesn’t exist on the hard drive anymore, other ways of recovery are possible and the file can still be reconstructed in some way or the damage can be lessened.
Not all data recovery happens by magnetic tape especially that it takes time and it can be dangerous; there are other techniques that combine several technologies, just as Instant Recovery. Basically, the user works in a backup virtual machine that simulates the file thanks to a snapshot taken immediately at the time of data backup while the actual recovery happens in the background. Once done, the users are redirected back to the original virtual machine. However, one way to save time is to prevent data from getting lost in the first place by using data loss prevention software.
Back up your data
It is also very important to always remember to backup your data and files to prevent their perpetual loss. Data backup is basically creating an exact copy of your files, and there are many ways to do it. Data backup can be done on a flash drive, an external drive, by clone, which is an exact copy of the primary hard drive, or by cloud software that keep your computer automatically backed up and are usually very safe. You should figure out with backup method works best for you, and remember that the first two methods have to be done manually, so if time-management is important for you, automatic data backup systems are usually better.
If the person is not a computer expert himself, the wise thing to do would be to contact a data recovery technician, but make sure they work by a no recovery, no fee policy. That way, you’re more likely to be able to trust them because they sound confident of what they can do, and second, you won’t have to pay for no results.
