Backup of virtual machine mounted on VCB Proxy fails with "Corrupt selection tree" or backs up wr (78912)

Date: Aug 08
Product & Version: All NVBU
OS Version: Windows 2003
Module & Version: VMware Plugin 1.0.11
Application version: ESX 3.x

Symptoms:
The user has a VCB Proxy configured and expands the VMware plugin on it to reveal Windows virtual machines. He then right-clicks and mounts them to be able to select individual files on this virtual machine for backups and runs this backup job. It either fails with the messages "Corrupt selection tree - root filesystem node not found" and "Invalid selection tree", or the backup completes, but actually backs up files from a different virtual machine (evident in the message "The target VM for this backup job is 'VM-Wrong' uuid '#####').

VMW-61 and VMW-62 have identified the problems and they will be fixed in the next release of the VMware Plugin.

"Corrupt Selection Tree" - during file-level backup selection, this is caused by ticking an entire virtual machine, instead of ticking the individual drives underneath. In order to resolve this, create a new selection set and tick the drives individually.

Backups backing up the wrong machine - when saving a backup options set for any VMware backup, the machine selection is saved along with the options set. If another backup is created, with potentially a different selection, but the same option set is reused, it will backup the virtual machine the set was originally created for. In order to work around this, don't use option sets for virtual machine backups, or create an individual option set for each selection set.
