1
In the Navigation pane, click Create Backup Job to start the configuration wizard.
You can also start the wizard from the Guided Configuration link. In the Navigation pane, click Guided Configuration, and then on the NetVault Configuration Wizard page, click Create Backup Jobs.
2
In Job Name, specify a name for the job. Assign a descriptive name that allows you to easily identify the job for monitoring its progress or restoring data.

Click Create New to open the NetVault Backup Selections page.
*NOTE: To switch between the two views, select the ESX/ESXi or vCenter Server, and in the Actions list, click Toggle Inventory View. This option is only available when server node is open.
Back up all virtual machines within a container: Select the container node. Data selection is possible at all levels starting from the Datacenter node.
Back up individual virtual machines: Open the applicable container nodes (for example, Datacenter, Cluster, Resource Pool, and other nodes), and select the virtual machines that you want to back up. In the VMs and Templates view, open the folder node, and select the virtual machines that you want to back up.
Back up individual virtual disks: Open the virtual machine node, and select the disks that you want to back up. Note the following:
e
Click Save, and in the Create New Set dialog box, type a name for the set. Click Save to close the dialog box.

Under Backup Type, select one of the following options.
c
Under VM disk selection options, select one of the following options.
d
Under Other Options, configure the following settings.

When you run a backup job, the plug-in creates a snapshot named “BKB_SNAP” on the virtual machine to back up the selected data. Regardless of whether the backup completes successfully or fails, the plug‑in removes the snapshot on job completion. The plug-in also removes the snapshot if the job is aborted or the parent or child processes are terminated for any reason. However, if a job exits abnormally, the cleanup process may fail to remove the snapshot. To address such cases, the plug‑in provides an option to delete the snapshot when you run the job next time.
You can select the Remove snapshots from previous backups check box to remove any existing snapshots when you run the current job. Only the snapshots named “BKB_SNAP” are removed from the virtual machines. This option does not remove any other snapshots that exist on the virtual machine.
When configuring Maximum Number of Parallel Streams, consider the following:
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. The log messages and log context show which virtual machines have failed for the job. When you restart the job later, the plug-in runs an Incremental Backup job to back up the failed virtual machines.
You can restart a job from the Job Status page. For more information about this method, see Restarting a backup job. A restarted instance does not back up virtual machines that are added to the host after the initial job is run.
NOTE: If all virtual machines fail for a job, the job status is set to Backup Failed. You cannot restart a failed backup job.
e
Click Save, and in the Create New Set dialog box, type a name for the set.
6
To submit the job for scheduling, click Save & Submit. You can monitor the job progress from the Job Status page and view the logs from the View Logs page.
To save the job definition without scheduling it, click Save. You can view, edit, or run this job from the Manage Job Definitions page. This job is not displayed on the Job Status page until you submit it.
For more information about Job Status, View Logs, and Manage Job Definitions, see the Dell NetVault Backup Administrator’s Guide.

Additional notes

To create the first Full Backup of a virtual machine with Changed Block Tracking enabled, the target virtual machine must be powered off to enable CBT. For more information, see http://kb.vmware.com/kb/1031873. The virtual machine can be restarted as soon as the backup starts transferring data.
The re-configuration of Changed Block Tracking takes effect only after the virtual machine goes through a stun and unstun cycle, including power-on, resume after suspend, migrate, or snapshot create, delete, or revert operations.
Creates a non-CBT Full Backup, unless CBT is already enabled for the virtual machine or you have selected the Enable Change Block Tracking for VM check box for the Incremental or Differential Backup.
Log message: Failed to write index of backup to the database.
Log context: The index for this backup may be retrieved and added to the database by scanning the backup media.

Restarting a backup job

The Plug‑in for VMware provides the ability 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.
All restarted instances appear as a single saveset on the Create Restore Job — Choose Saveset page.
