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.

1
Start the Backup Job Wizard, and click Create New next to the Selections list.

Select the target virtual machine, and in the Actions list, click Reset Change Block Tracking.

a
Click Create New to open the NetVault Backup Selections page.
Hosts and Clusters Inventory View: Open the Datacenter, Cluster, Resource Pool, and other nodes to display the available virtual machines.
VMs and Templates View: Open the Datacenter and folder nodes to display the available virtual machines.
A folder is created in the Working Directory (set in the Configure dialog box). This folder is assigned the same name as the selected virtual machine
A Drives node is added to the selections tree. This node is displayed under selected virtual machine.
NOTE: If the boot disk is not the first disk among the disks attached to a virtual machine when they are arranged in the controller:device order (that is, ide0:0, ide0:1, scsi0:0, scsi0:1, and so on), the mounting operation might fail for the virtual machine.
e
Open the Drives node to display the available drives. Select the drives, or open the nodes further to display the directory tree, and select the files and directories that you want to back up.

Backup Type

Select the applicable option from the following:

For more information about file-level backup types, see File-level backups.

Create Dump Type Backup

To create Dump Type Incremental or Differential Backups, select this check box. With these backups you can only restore those files that were backed up in a particular Incremental or Differential Backup.

Check For Files Being Modified During Backup

To mark the files that are being modified during a backup as “in flux,” leave this check box selected. During restore, these files are not restored by default. To restore these files, you must set the option Restore Files Modified During Backup on the Restore Options Set.

If you do not want to check for files that are being updated during backup, clear this check box.

Enable Restartable Backup

To add the ability to stop a job and resume it later from that point, select this check box.

When you stop the job, the plug-in generates an index for all items that have been processed up to that point and writes the index to the backup media and NetVault Database. When you restart the job later, the plug-in runs an Incremental Backup job to back up the remaining files and folders.

You can stop and resume a job from the Job Status page. For more information, see the Dell NetVault Backup Plug-in for FileSystem User’s Guide.

Path to Backup Log

To generate a backup log file, type the filename. The log provides a list of files that are selected for the backup. The files that are backed up successfully are marked with an “o” and the others are marked with an “x.” You can use this option with an Incremental Backup to determine which new or changed files have been backed up. If you specify an existing filename, the plug-in overwrites the file. The log file is created in CSV file format, and includes details such as file size, date modified, and file type.

Click Save, and in the Create New Set dialog box, type a name for the set.
Click Save to close the dialog box.

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.
