Jeff, do you have NT servers running ADSM? I think last time I looked at this it seemed like you should be able to use ADSM on NT to backup your filers using a CIFS connection to a filer share. See this IBM ADSM FAQ section: ---
No, for better or for worse (each to their own..) we are an NT-Free environment.
100% UNIX.
And although I can use ADSM via NFS, Id like to keep my application servers running apps, and the filer doing filer things (like backups).
