Answer:

Explanation:

If we make a database backup we could recover our data if something fails, for example, in a system crash, transaction errors, viruses, incorrect commands execution, etc.

There are some types of backups:

Full database backup: Everything is safe in this backup.

Differential backup: this backup only stores the changes in the full backup.

Transaction log backup: contains all transactions that had happened to the database.
