Hi.
It seems that I can't disable software compression in amanda. I tried
everything that could in my opinion have an impact on compression. But
no luck. The problem is that i have a relatively slow machine and it
takes forever to complete the backup. If I check the processes i see this:
19021 ? S 0:00 \_ /bin/sh /usr/sbin/amdump AAA1
19031 ? S 0:00 \_ /usr/lib/amanda/driver AAA1
19032 ? S 0:01 \_ taper AAA1
19037 ? S 0:01 | \_ taper AAA1
19033 ? S 0:08 \_ dumper0 AAA1
19034 ? S 5:31 \_ dumper1 AAA1
19074 ? S 0:08 | \_ /bin/gzip --best
19035 ? S 0:00 \_ dumper2 AAA1
19036 ? S 0:00 \_ dumper3 AAA1
19066 ? S 8:59 \_ chunker1 AAA1
I suppose that there shouldn't be a "gzip --best" if I disable the
compression. I also tried to use the directive "compress fast" in the
"define dumptype" section, but no luck. "gzip --best" is still there (it
should at least change to "gzip --fast").
This is my "disklist":
server /boot tar_midp
server / tar_midp
And this is my "amanda.conf":

mailto "root"

The installation is on Debian etch (4.0). Amanda (server and client)
version 2.5.1p1-2.1
Anyone any idea?
