Note that there is space for improvement in the backup/restore experience with vCD (we know).

Seems that this question relates to VCB and not vCD! Moved it to a more appropriate section of the forums.

You could still use VCB with pre and post scripts to backup with BackupExec 2010, however you'd likely be better off going with the BackupExec Agent for VMware Virtual Infrastructure, which uses the vStorage APIs. VCB is basically a dead-end product. The vStorage APIs are the future.
Before you dive in to the BackupExec AVVI solution make sure you read the attached FAQ and also the BackupExec Admin Guide fully.
