Replicating a Backup


This section describes how to replicate a manual or an automated backup. The new backup must have a different name from that of the original backup.


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

Backup Retention Policy

  • If an instance is deleted, the automatic backup of the instance will be deleted.
  • If the automated backup policy is enabled, the automated backups will be deleted after the backup retention period expires.
  • 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 unless you delete them.
  • If storage space occupied by manual backups exceeds the default storage space, additional RDS storage costs may incur.


  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click Service List. Under Database, click Relational Database Service to go to the RDS console.
  4. On the Backup Management page, locate the manual backup to be replicated and choose More > Replicate or locate an automated backup and click Replicate in the Operation column.
  5. 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 must consist of a maximum of 256 characters and cannot contain the following special characters: >!<"&'=

  6. After the new backup has been created, you can view and manage it on the Backup Management page.
