Will Backups Be Encrypted After Disk Encryption Is Enabled for My RDS Instance?

If you enable disk encryption when creating an RDS for SQL Server instance, the disk encryption status and the key cannot be changed later. Disk encryption will not encrypt backup data stored in OBS.

If disk encryption or backup data encryption is enabled, keep the key properly. Once the key is disabled, deleted, or frozen, the database will be unavailable and data may not be restored.

  • If disk encryption is enabled but backup data encryption is not enabled, you can restore data to a new instance from backups.
  • If both disk encryption and backup data encryption are enabled, data cannot be restored.
