Replicating a Backup

Scenarios

RDS supports replication of automated and manual backups.

Constraints

You can replicate backups and use them only within the same region.

Backup Retention Policy

• RDS will delete automated backups when they expire or the DB instance for which the backups are created is deleted.
• If you want to retain the automated backups for a long time, you can replicate them to generate manual backups, which will be always retained until you delete them.
• If the storage occupied by manual backups exceeds the provisioned free backup storage, additional storage costs may incur.
• Replicating a backup does not interrupt your services.

Procedure

1. Log in to the management console.
2. Click in the upper left corner and select a region and a project.
3. Click in the upper left corner of the page and choose Database > Relational Database Service.

5. In the navigation pane on the left, choose Backups & Restorations. On the displayed page, locate the required backup and click Replicate in the Operation column.
6. In the displayed dialog box, enter a new backup name and description and click OK.
   • The backup name must consist of 4 to 64 characters and start with a letter. It can contain only letters (case-sensitive), digits, hyphens (-), and underscores (_).
