The process that is used to recover the data that was lost is called Data Recovery. Data may become corrupted, inaccessible, or may be inadvertently lost or erased. In the information technology field, restoring data is called data recovery. It can be restored by backing up to laptop, desktop or hard drive, server, etc.

What Causes Data Loss?

In the generic scenario, data is always lost by human error rather than virus attacks. Many of the reasons for data loss are due to natural disasters, component or equipment failure, power outages, inadvertent data deletion, accidental hard drive formatting, hard drive read / write head problem, hard drive failure. software, using the PC even if it is in a damaged state or has shown signs of damage or failure, etc.

How is the data recovered?

The data recovery process changes according to the situations in which the data might have been lost. The software can be used to restore deleted data. The backup is performed and then the data is restored. Lots of software available for laptops and desktops have the function that allows the customer to recover his lost files by himself. If the user had to restore the lost data from the database that has been corrupted by backup, the experts should be consulted as the procedure is complicated. Data recovery service centers can also be asked for help if inadvertently deleted files that are not backed up are to be restored. These files are not accessible but are still saved on the hard drive. The information related to the file and files are stored in separate places. This makes the data recovery process easy and possible.

In the Windows operating system, the file allocation table is used. Track file location and files that are stored on hard drive. It is the same as the table of contents of the book with the difference that the pages are the files. When data is lost and needs to be recovered, then there is something wrong with the file allocation table. The files to be recovered are still on the hard drive. The file can be recovered if it is not damaged and is present on the hard drive. If the data files are missing or damaged, other techniques can be used to recover them. Even physically damaged hard drives can be rebuilt to recover data. Many technologies and processes are combined to recover the data. It is not recovered just by restoring data from tape. This recovery process takes time for some data and applications.
