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.
Note: When an image backup is interrupted or fails due to some reason,
the client attempts to clean up the incomplete backup on the IBM® Storage Protect server when the image backup is run again. If
the server option BACKDEL is set to Yes, the client will remove the incomplete image backup before
attempting another image backup. If the BACKDEL option is set to No, the client will inactivate the
incomplete backup. The inactivated backup will expire according to the policy definition on the
server.
