Today, AWS Backup announces support for EBS Snapshots Archive in the AWS GovCloud (US) Regions, allowing customers to automatically move EBS Snapshots created by AWS Backup to EBS Snapshots Archive. EBS Snapshots Archive is low-cost, long-term storage tier meant for your rarely-accessed snapshots that do not need frequent or fast retrieval, allowing you to save up to 75% on storage cost.
You can now use AWS Backup to transition your EBS Snapshots to EBS Snapshots Archive and manage their lifecycle, alongside AWS Backup’s other supported resources in the AWS GovCloud (US) Regions. EBS Snapshots are incremental, storing only the changes since the last snapshot and making them cost effective for daily and weekly backups that need to be accessed frequently. You may also have EBS snapshots that you only need to access every few months or years, retaining them for long-term regulatory requirements. For these long-term snapshots, you can now transition your EBS snapshots managed by AWS Backup to EBS Snapshots Archive Tier to store full, point-in-time snapshots at lower storage costs.
