Can anybody recommend the best way to estimate whether all my filesystems
will fit onto one tape? Right now I'm running a 15-day incremental cycle,
but I want to remove friday from that cycle, and do a full backup. The
problem is, it'll take me a LONG time to login to each server, df -k, etc.
to estimate the sizes.

I'm guessing that maybe Amanda might have this info stored away in some
secret file somewhere, or I can use some deft command-line switches to
"audit" all my file systems.

Any ideas?
