You can add your own comments about each backup job to make it easy to find the right backup version of your database for recovery. ZRM for MySQL also provides reports about the state of MySQL during backups, e.g., how much time it took to flush memory buffers before the snapshot was taken. Formatting for backup reports is flexible. For example, you can receive reports automatically via RSS feed making it easier to consolidate reports for a dashboard or any monitoring application. ZRM Enterprise Edition provides 9 predefined reports and allows to customize reporting on over 30 items.
