Performing an image backup using the command line

Use the backup image and restore image commands to perform image backup and restore operations on a single volume.

You can use the snapshotproviderimage option with the backup image command or the include.image option in your dsm.opt file or on the command line to specify whether to perform an offline or online image backup.

Use the mode option with the backup image command to perform an incremental-by-date image backup that backs up only new and changed files after the last full image backup. However, this only backs up files with a changed date, not files with changed permissions.
