Configuring Backup Encryption

Scenarios

You can enable backup encryption for instances that do not have disk encryption enabled during instance purchase.

Constraints

  • If you want to enable backup encryption for an instance with disk encryption enabled, see Will Backups Be Encrypted After Disk Encryption Is Enabled for My RDS for MySQL Instance?
  • Only enabled KMS keys using the AES_256 algorithm can be used for backup encryption.
  • After backup encryption is enabled, ensure that the selected key is enabled. If the selected key is disabled or deleted, encrypted backups will be unavailable and backups will fail.
  • Enabling or disabling backup encryption only applies to new backups and does not affect the encryption status of existing backups.
