Could one use DDR + Amanda to backup z/VM volumes? Perhaps run DDR via cpint and Amanda it to a network tape drive like Ultrium LTO2?
What would you DDR it to? I guess if you used DDR2CMSX and put the CMS output file on an NFS-exported SFS directory, then sure. And since you can export SFS and BFS via NFS, then you could use Amanda to do file-level backups of those too.
We did have a mostly-working Amanda client for CMS (minidisk only); would that be of use? I could see about releasing it on our website (it's not really production-quality yet, but if it proves generally useful, we might be able to justify some more development of it). That actually did file-level backups of minidisks into Amanda storage.
So between those two things, you could have both file- and volume- level backup via Amanda.
However, we've recently started recommending Bacula instead of Amanda; it is a good deal more powerful and flexible. The one thing that Amanda did, that Bacula doesn't, and that I miss, is that Amanda handled scheduling differential/incremental/full dumps on its own, while Bacula requires you specify them according to a fixed schedule. However, Bacula's docs are about a zillion times better than Amanda's, which, right there, makes it a win as far as I'm concerned, and I will put up with needing a little more tape/disk space in return.
We have not, however, done any investigation of a CMS client for Bacula yet.
