For Windows 2008 R2 clients and Windows 7 clients, you can back up any VHD files that you may have created. No special method is required to back up VHD files.
In the NetBackup,
Archive, and Restore interface, a VHD file looks the same as a
physical hard disk only if it has been mounted manually. For
example, test.vhd
resides on drive C
and is mounted as drive E.
In this example, assume
that you select both drive C and drive E for backup. To prevent a
duplicate backup, the drive C backup excludes the test.vhd
file since drive E is also selected for
backup.
If you select only drive
C for backup, the test.vhd
file is
included since it resides on that drive.
