Backup

What is a backup? Why do we need a backup?

A backup (data protection) means being able to return to a previous state.

One needs a backup in case of data loss, tampering or lack of access to the original data.

 

The implementation of a backup environment depends, among other things, on the requirements for retention time, number of copies (also remote) and restore speed. The environment to be backed up must also be considered to determine the best backup tools to consider.
