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

If you enable disk encryption when purchasing the instance, it cannot be disabled afterward but you can modify the key. For details, see Configuring Disk Encryption.

Once enabled, disk encryption does not encrypt backup data stored in OBS. To enable backup data encryption, submit a service ticket.

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 encryption are enabled, any lost data cannot be restored.
