Database Backup (DBS) provides the following instance types: micro, small, medium, large, and xlarge. You can upgrade instance types based on the amount of backup data and restoration performance requirements.


  • For more information about how to select instance types, see Select an instance type.
  • After you upgrade an instance type, DBS immediately upgrades the settings of the instance type and improves the backup and restoration performance.
