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

  • RDS for MySQL:

    If you enable disk encryption during instance creation, the disk encryption status and the key cannot be changed later. Disk encryption will not encrypt backup data stored in OBS buckets.

  • RDS for PostgreSQL:

    If you enable disk encryption during instance creation, the disk encryption status and the key cannot be changed later. Disk encryption will also encrypt backup data stored in OBS buckets.

  • RDS for SQL Server:

    If you enable disk encryption during instance creation, the disk encryption status and the key cannot be changed later. Disk encryption will not encrypt backup data stored in OBS buckets.

If disk encryption or backup data encryption is enabled, keep the key secure. Once the key is disabled, deleted, or frozen, the DB instance will be inaccessible 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.
