Tell about regular backups and verifiable recovery.

Regular backups are systematic copies of data created to protect against loss. It is important to set a schedule (daily, weekly) depending on the criticality of the data and the volume of changes.

Test recovery is the process of testing data restoration from backups to ensure they work and the data is not corrupted.

Key points:

• Automating backups with status notifications.
• Storing backups in different locations (locally and in the cloud).
• Regular testing of recovery in a test environment.
• Documenting recovery procedures.

Example: if you have a database, you can set up daily dumps and weekly full restorations on a test server to verify integrity.

This reduces the risk of data loss and allows quick recovery in case of failures.
