AWS Backup Now Lets You Archive EBS Snapshots in Air-Gapped Vaults
AWS Backup's logically air-gapped vaults now support archiving Amazon EBS Snapshots to a cheaper storage tier, perfect for backups you rarely need. You can set up monthly backup plans that automatically transition snapshots to Amazon EBS Snapshots Archive, keeping your immutable backups secure and compliant while cutting storage costs—available across all AWS Regions where both services are supported.
