Express performs backup and restoration regardless of the state of the server to be backed up. Therefore, make sure that both copy source and destination volumes are inaccessible in order to ensure consistency of backup data. For absolute assurance of data consistency, we highly recommend to stop the target server before executing backups and restorations. If the server cannot be suspended, dismount a target volume using the OS function to prevent data within a file cache from being reflected and inhibit access to the target volume.
