Hi, i use maildir format,
its no problem to backup big maildirs with rsync,
at backup i see no "real" relation with with filessystem until you use a
modern one ( i.e. ext3... ), perhaps you might use nfs or gfs
for redundancy solutions
after all this type of backing up ( tar , rsync, i.e by cron )
is only a snapshot ( maybe ok on your side ), but i.e you may use
always_bcc i.e with postfix
or imapsync etc
choosing zfs maybe is the right choice anyway
i ve read much good about it, but i dont see what it might helpfull at
backup
