The process that is used to retrieve the data that was lost is called Data recovery. The data can get corrupted, it can get inaccessible, or can be lost or deleted unintentionally. In the IT field, data restoration is called data recovery. It can be restored by taking backup to the laptop, desktop computer, or the hard drive, server, etc.
What causes the Data Loss?
In the generic scenario, the data is always lost by human error than that of the virus attacks. Many reasons for data loss are due to some natural disasters, failure of the component or equipment, power blackouts, unintentionally deleting the data, formatting the hard drive accidentally, the issue in the read-write head of the hard drive, crashing of the software, using the PC even if it is in a damaged state or has thrown the signs of damage or failure, etc.
How is the Data Recovered?
The process of recovering the data changes according to the situations in which the data could have been lost. The software can be used to restore the erased data. The backup is taken and then it restores the data. Lots of available software for laptops and desktop PCs have the facility that allows the customer to self recover their lost files. If the user had to restore the lost data from the database that has been corrupted using a backup then the experts should be consulted as the procedure is complicated. The service centers for data recovery can also be asked for help if unintentionally deleted files are to be restored that have no backup. These files are not accessible but are still saved on the hard drive. The information related to the file and the files are stored in separate places. This makes the data recovery process easy and possible.
In windows OS, the file allocation table is used. It tracks down the location of the file and files that are stored on the hard drive. It is the same as the table of contents of the book with the difference that pages are the files. When the data is lost and it demands to be retrieved then there is some problem in the file allocation table. The files that are to be recovered are still on the hard drive. The file can be recovered if it is undamaged and is present on the hard drive. If the data files are missing or damaged then some other techniques can be used to recover them. Even the physically damaged hard drives can be reconstructed to get the data back. Many technologies and processes are combined to recover the data. It is not recovered alone by restoring the data from the tape. This recovery process takes time for some data and the applications.
