Hello Tim,

In a few words I agree with Betsy : don't tell about incremental, it's too
hard to explain to the end-users. I prefer speaking of "full backup updated
every day", it's much more close to adsm's reality, I think.
In general, we use adsm's normal incremental backup. But for some data we
need regular snap shots (say the usual monthly or yearly backups), so we do
archives.
There is just one case I'm studying at the moment (any advice appreciated
:-) were I have a big file server (150000 files / 10 GB) that is
intensively updated. I expect its files to reside on a lot of different
volumes (3490E ~ 1.5 GB) and I'm afraid that I'd need a huge number of
media mounts in case I had to restore this server after a crash, so I'll
perhaps try to have monthly "full" (selective, adsm speaking) backups, so
that all the files get grouped now and then, and the number of mounts limited.

Hth,
