Guess I missed the original post...
We have been using Vxvm 3.5 snapshots with good results. We have some
fairly cheap SATA disk we use for backups, and using veritas flashsnap,
which allows for "changed data only" snapshots, it seems to work quite
well. We do not use netbackup its self to manage the snapshots, we just use
a script that is scheduled in our enterprise scheduling system.
In some of the veritas flashsnap documentation, they do have the process layed
out to perform this.
I will note that we did have problems with write order using the veritas vxvm
4.0 (version 20 DCO) snapshots, so we did fall back to the veritas vxvm version
0 DCO, from vxvm 3.5.
