AWS Backup for Amazon S3 adds support to copy your Amazon S3 backups across AWS Regions and accounts in AWS opt-in Regions (Regions that are disabled by default).
With the support of Amazon S3 backup copies in multiple AWS Regions, you can maintain separate, protected copies of your backup data to help meet the compliance requirements for data protection and disaster recovery. With the support of Amazon S3 backups across accounts, an additional layer of protection is provided against inadvertent or unauthorized actions.
The ability to copy Amazon S3 backups across AWS Regions and accounts is now available in all commercial AWS Regions. For more information on regional availability and pricing, see AWS Backup pricing page.
