Actually the response from me below was to someone that didn't want to use
the B/A client to get the individual file level changes.  We back up VMs
both ways.   We had our first DR test using VMs last Feb in Boulder, CO at
IBM and everything went without a problem.

We use the VM snapshots for bare metal restores and the B/A client to
bring the VM back up to date with the individual file level changes.  VMs
are snapshot about once a month.

Hi Buddy,
   I'm afraid I have to disagree somewhat. You've only described the
"fullvm" backup option, and that's not what most people use, at least on
Windows.

   The TSM default behaviour is actually to back up individual files from
each guest (windows) to each node set up for that guest. Doing a restore
only requires a guest to have TSM installed if you *want* to restore
there.
You could alternatively use the usual restore asnode (grant proxy) stuff,
if
you prefer - and that's what most of my VCB customers do.

  Hope that clarifies things a bit.
