Backing up a virtual disk
The Citrix Provisioning™ server treats a virtual disk image file like a regular file, but the target device treats it as a hard drive. The procedure for backing up a virtual disk image file is the same as backing up any other file on your server. If a virtual disk image file becomes corrupt, restoring it requires replacing the corrupted file with a previous, functional version.
Note:
Do not back up a virtual disk while its being used or while it is locked. Citrix® recommends backing up these disks using your normal provisioning server backup routine.
