Hello...
Since upgrading amanda, I'm seeing estimates ( via amstatus) way larger than
they should be. I went from something before 2.5.1p3 , to 2.5.2, to 2.5.1p3,
2.5.2, 2.5.1p3, and now 2.5.1p3-20070516 ( on rhel4 x86_86 ). The wrong
estimates could be a result of going back and forth between versions, but I
doubt it. The estimates seem to be consistantly about twice what they should
be. The "how many tapes do I need" part of amdump seems to work correctly, so
this might be a pure amstatus display issue. On the DLEs that I can see
individually and are relatively stable in size, the real dump size is about 50%
of the estimate and the compression is also about 50%. So I suspect something
is using the original size instead of the compressed size.
in amanda.conf:
compress client
estimate server
encrypt server
server_encrypt "/usr/sbin/amcrypt-ossl-asym"
and a number of DLEs with:
skip-incr
from amstatus:
(something like)
wait for writing: xx 8301m 16420m ( 50.56%) ( xx.xx%)
from amadmin info client
compressed size, Full: 54.1%, 54.1%, 54.1%
compressed size, Full: 54.7%, 54.7%, 54.7%
etc.
OR
since the difference for me is twice as large, or half as large, depending of
how you look at it ;) the problem could also be a division/multiplication error
somewhere. e.g. (total/4) vs (total/3) vs. (total/2)
