I am switching from BudTool to Veritas Netbackup.

Aren't we all? (*sigh*)

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?

I currently backup via NDMP with Budtool. It is true that with NDMP you are dependent on the OS release, but the backup vendors usually keep up with the major OnTap releases. The advantages of NDMP backup still outweigh NFS. Although we HAVE had situations where an OnTap upgrade broke NDMP backups thru Budtool as well. I still plan to use NDMP with Veritas (or Legato, or Backup Exec, or...)
