AWS RDS automated backup


Can RDS automated backup be done in another region? I am seeing conflicting data from AWS:

https://aws.amazon.com/blogs/database/implementing-a-disaster-recovery-strategy-with-amazon-rds/ says that automated backups are limited to single region.

https://aws.amazon.com/about-aws/whats-new/2020/01/aws-backup-supports-cross-region-backup/ talks about AWS Backup and says that RDS has cross-region support.

I am now confused. Can someone please help? My goal is disaster recovery, as highlighted in the first link.


Solution

  • For the first link you shared it is about the RDS snapshots (automatic snapshots) that are taken by the RDS service. These snapshots are only accessible within the single AWS region in which the snapshot was taken, however you can copy an automatic snapshot which will then make it a manual snapshot. From here you would then be able to copy the snapshot to another AWS region.

    The second link is actually referring to the AWS Backup service which is a service for centrally managing your backups. When this snapshot is taken the Backup service can actually handle the process of copying the snapshot to another region for you.

    Its worth noting that AWS Backup Service is a more recent addition to AWS, whereas the automated snapshots for RDS have existed since the service launched.
