OCUM vs VSC

I have multiple objects to back up and SnapVault to a 7-mode target. VMs living on NetApp filers, NetApp CIFS volumes, physical servers requiring OSSV. This environment is all 7-mode.

I figured OCUM Core for physical, and OCUM Host Package for virtual.

OCU-HP documentation says it does pretty much everything that VSC does--and maybe more--at least as far as backup and restore are concerned.

Three questions:

1. Is there any reason for me to bother with VSC, if OCUM-HP does include all of VSC's functionality?

2. Any downsides to creating a single backup policy to backup all my VMs at once, if they all have the same scheduling/retention requirements? Assume I'm not taking vmware snapshots, just array-level snapshots.

3. When are vmware snapshots recommended as part of backing up a VM? I've seen postings that point out downsides of taking vmware snapshots, such as momentary VM freezes, etc. Is crash-consistent backup of a VM, when it's backed up with no vmware snapshot option, good enough for most circumstances, except maybe for DB applications?
