Restarting a backup job

The plug-in includes the option to restart a job to back up only those virtual machines that failed previously. To use this method, you must configure the backup option Enable Restartable backups for the job. For more information about this option, see Performing image-level backups. When a restartable backup completes with some failed virtual machines, the plug-in generates a backup index for the completed virtual machines and sets the job status to Job Stopped. You can restart this job from the Job Status page.

NOTE: The Restart method does not work if you select multiple jobs simultaneously.

Resetting CBT on a virtual machine

During Incremental or Differential backups, if the plug-in is unable to determine the changed disk sectors for a virtual machine, it reports an error — “Failed to determine disk areas to back up” — and backs up the entire disk. When this error occurs, use the following procedure to reset change block tracking for the virtual machine. Before proceeding, delete any existing snapshots of the target virtual machine.

Start the Backup Job Wizard, and click Create New next to the Selections list.

Click the target virtual machine, and select Reset Change Block Tracking from the context menu.
