Aaron,
I may be wrong, but I'd have thought that the TEE was in memory,
then piped again to gzip and with the final output being put to
an index directory specified in amanda.conf.
(or, since I haven't really worked with amrecover, I could be
completely wrong)
In our case, the amanda directories are on a different device, I
don't know anything about intermediate files, but I'd have expected
anything written to be of very low volume, essentially directory
listings, as opposed to the actual TEE'd data stream, which would
be huge, but hopefully never touching disk.
There are levels of internals here that I'm only guessing at.
thanks,
Brian
