AWS RDS Backup Methods

AWS RDS Service provides two backup methods:

A] Automated backups
B] User-initiated DB snapshots

Automated backups are initiated during the creation of an RDS instance. You set the backup window, the retention period for the backups and you’re ready. Bingo…!!!

Although automated backups seem attractive because they are easy to manage, they have some constraints.
1. Retention : There is a 35-day retention period limit. After exceeding that limit, the snapshot is then deleted.
2. Deleted database : If you accidentally delete a database for any reason, automated backups are going to be removed too.
3. Disaster Recovery : Automated backups can only be restored from within the same region. If you have a DR strategy, you might want to move the snapshots between multiple regions.

These 3 constraints can be resolved with the User-initiated AWS RDS DB snapshots.

1. AWS RDS DB snapshots can be retained for as long as you wish. Means RDS manual snapshots will only be deleted when the administrator specifically deletes the RDS snapshots.
2. AWS RDS DB snapshots are not removed if you accidentally delete the database.
3. AWS RDS DB snapshots can be moved from one region to another without any constraint.

Amazon Web Services gives us three ways to take manual DB Snapshots :

  1. AWS Management Console
  2. AWS CLI Command line utility
  3. Various Amazon SDKs.

As long as manual snapshots are taken regularly and kept secure, it’s easy to recover your database within a few minutes. Ultimately, you have to pay for the backup storage that you use until those backups are deleted.

In order to really enjoy RDS manual snapshots, it is best practice to automate manual RDS snapshots to serve your database backup policy. Rather, I would emphasize you all to use AWS Lambda Service to automate RDS manual Snapshot backup strategy.

H@ppy doing Automation ahead…..!!!

OK, folks that’s it for this post. Have a nice day guys…… Stay tuned…..!!!!!
