Which "tape changer" didn't work?  The physical hardware or something
related to Amanda?  If Amanda, which changer did you try and how did
you configure it?  And what version?

Not right now.  It's been suggested before but isn't likely to happen
any time soon.

Compression has nothing to do with gathering the estimates.  Amanda needs
to gather estimates so it know whether everything is going to fit on
the tapes you have allocated for the run, and if not, which levels to
defer until it does (also, what can be promoted).

Is Amanda doing more than a level 0 estimate (check the amdump.<nn> file)?
If so, how do you have it configured to do full dumps every day?

Have you increased etimeout?  That's a workaround for your case, but
doing backups is better than not doing them :-).

One hack would be to take the gtar-wrapper code from:

  ftp://gandalf.cc.purdue.edu/pub/amanda/gtar-wrapper.*

and have it do "fast" estimates for you.  It should not be hard to add
to the framework that's there.

Have you actually tried a "du -sk" to see if it's any faster?  Both it
and tar have to traverse the whole directory tree and stat everything.

If you're doing whole file systems, "df -k" would be the way to go.
Or switch to using dump instead of tar (although you'd have to be
comfortable with those ramifications).
