multiple gzip on same data!?
2005-06-29 12:09:30
Hi guys,
I've got my configuration mostly sorted out now, so it's doing what I
want it to. However, I've got a question about some weird behavior I'm
seeing on my AMANDA server. I'm using the srvcompress option because the
servers I'm backing up from are rather slow, and when backing up, I see
the following on the AMANDA server:
9675 ? S 0:00 \_ /USR/SBIN/CRON
9676 ? Ss 0:00 \_ /bin/sh /usr/sbin/amdump weekly
9685 ? S 0:01 \_ /usr/lib/amanda/driver weekly
9686 ? S 4:24 \_ taper weekly
9687 ? S 0:59 | \_ taper weekly
9699 ? S 9:45 \_ dumper0 weekly
10629 ? S 96:19 | \_ /bin/gzip --fast
10630 ? S 0:00 | \_ /bin/gzip --best
9700 ? S 6:52 \_ dumper1 weekly
10086 ? S 149:32 | \_ /bin/gzip --fast
10087 ? S 0:21 | \_ /bin/gzip --best
9701 ? S 0:00 \_ dumper2 weekly
9702 ? S 0:00 \_ dumper3 weekly
Now, why oh why is it doing *two* gzip operations on each set of data!?
It looks like the gzip --best isn't actually getting that much running
time, so is there something going on here that's faking me out, and it
isn't *actually* gzipping everything twice? :)
