AWS Backup Lets You Write Directly to Air-Gapped Vaults

AWS Backup now allows customers to back up data directly to logically air-gapped vaults, providing enhanced security and recoverability while reducing storage costs. Previously limited to storing copies, air-gapped vaults can now serve as the primary backup target for backup plans, policies, and on-demand backups across supported AWS Regions.
