(Debian binary Amanda install, tar, Linux)
One of the things I back up is the DMZ logging server's /var/log
directory. The backup fails fairly pretty regularly because that's a
very busy place, even in the middle of the night. This must be a very
common problem. How can I get around it?
An excludes file. For /var I have one called excludes.var on the
target machine:
# cat /etc/amanda/DailySet1/excludes.var
./ftp/pub/*.updates*
./cache/yum/*
./cache/apt/*
./named/chroot/proc/*
./spool/squid/*
./www/html/jdk.docs/*
Then in the tape server's amanda.conf, set up a dump type like so:
define dumptype comp-root-tar-var {
comp-root-tar
comment "Root partitions with compression, special for /var"
exclude list "/etc/amanda/DailySet1/excludes.var"
}
Then in your disk list, use it:
dragon.localdomain /var comp-root-tar-var
I got the sense that he wanted to back them up.
I get around that problem by using snapshots. But I'm on Solaris 9,
where I have fssnap and a wrapper so that when Amanda calls ufsdump it
ends up doing a snapshot and backing up the snapshot. A description and
a couple of examples of this can be found at
http://wiki.zmanda.com/index.php/Backup_client#pre_and_post-_backup_scripts_.28wrappers.29
I haven't had to deal with that sort of thing on linux. If you aren't
set up for it, it could require rebuilding your linux machine to use
something like xfs. Doing a google search for "file system snapshot
linux" could get you into the basics of what is involved.
