Shaun, We use Veritas Netbackup via NDMP and it has worked well. Therefore no worries impacting net with backups. Never used BudTool. Upgrades to DOT have never been a problem. NOW keeps a page which lists NB versions sanctioned with the various DOT releases. I double-check it when considering upgrade. Hope that helps, Bob Francett BP Exploration/Alaska

... that is the question.

I am switching from BudTool to Veritas Netbackup. It seems, if I understand things correctly, that I can either back up my filers over NFS, or I can use NDMP and back them up to a locally attached tape drive, or to another filer with a locally attached tape drive.

NDMP seems the way to go, for performance and speed reasons. However, I stopped using NDMP with BudTool, because everytime I had to upgrade either BudTool or OnTap, I ran into compatability problems between the differing NDMP implimentations.

What has been the experience of those of you who are using Veritas and have tried the above solutions? Which method do you suggest I use, and why?
