Two drawbacks:
if you backup NAS direct to VTL (Filer to Server), libtype can't be VTL.
If you performe library sharing with the VTL, or use lanfree, all drives
of the VTL known to TSM must be made available to the other servers -
otherwise you have to use libtype SCSI.

Off the top of my head:
1) dsmserv will auto sense drives and paths for devtype=VTL
2) Some waits for operation completion are shortened when you tell TSM it's
all virtual, not real.
The latter is the larger benefit, of course.
I haven't seen any drawbacks to VTL.
