I would like to use a CentOS VM for a mirrored full backup of my CentOS mail server. Both are the same version and are up-to-date. I have found that without excluding certain directories the VM backup has kernel panic attacks and fails to load.

I use the following command to start the process:

rsync -avz -Kl -p --numeric-ids --exclude-from=/rsync_exclude.txt -e 'ssh -2 -c blowfish-cbc' user@my.domain.com:/ /

Question(s):

  1. Will there be any issues with the command being entered above?
  2. Which directories should I include in my "rsync_exclude.txt" to prevent issues on the VM backup?

I don't think this is the complete answer, but some are:

/sys
/proc
/tmp
/var/run
/var/lock
/dev
/mnt
# The following are stolen from Womble:
/var/cache
/var/tmp
/var/spool

I still get the kernel panic when excluding the mentioned folders – ricbax Nov 18 '09 at 1:09

Add /var/cache, /var/tmp, and /var/spool to Kyle's list.

You could have just put that in a comment on his post, I guess! – Suppressingfire Nov 17 '09 at 16:23

Or he could have taken all of mine, and then I get no points. We like to share points :-) – Kyle Brandt♦ Nov 17 '09 at 16:28
