Answer 2

Answer:

Backup is the copy of data used to restore or recover the data.

Explanation:

The backup of data is considered to be the rescue stuff. It is the copy of particular or desired computer data, which will get stored for later recovery. We can restore the same data, even when the original data is lost. It is one of the simplest forms of data recovery.  

But recovering complex configuration like recovering from computer cluster, database server, and active directory are always not feasible for backup mechanisms. This backup has at least one copy of the desired data for storage.
