(subject to discussion)
ldap, sql, filesystemdata, certificate, keys
just keep a few versions in case of screwup or disaster
svn
we probably need just one copy in case of disaster
logs
1 year
mail,irc
forever? actually those are already archives, so probably we
should move it to the 'backup' section
then for each item find a solution

(btw it supports encrypted backups with public/private keys)
