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.

Billing

Backups are saved as packages in OBS buckets.

After a DB instance is deleted, the free backup space of the DB instance is automatically canceled. Manual backups are billed based on the space required.

Procedure

1. Log in to the management console.
2. Click in the upper left corner of the page and choose Databases > Relational Database Service.
3. On the Instances page, click the target instance name. On the Backups & Restorations page, locate the backup to be replicated and click Replicate in the Operation column.
4. 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 uppercase letters, lowercase letters, digits, hyphens (-), and underscores (_).
   • The description consists of a maximum of 256 characters and cannot contain carriage return characters or the following special characters: >!<"&'=

5. After the new backup has been created, you can view and manage it on the Backups page.
