Sure, here's what I use for taking an image of a system. If you plan
to restore from your backup don't exclude your hostname, ssh host
keys, etc. You do want to exclude /proc and any NFS etc though. And
don't forget '--numeric-ids' as the specific numbers are referenced in
/etc/{passwd,group}

rsync -av --progress --delete-excluded --numeric-ids \
    --exclude=**/cdrom/* \
    --exclude=**/etc/hostname \
    --exclude=**/etc/mtab \
    --exclude=**/etc/network/interfaces \
    --exclude=**/floppy/* \
    --exclude=**/var/lock/* \
    --exclude=.bash_history \
    --exclude=.viminfo \
    --exclude=/.ssh/id* \
    --exclude=/etc/**/\@* \
    --exclude=/etc/**/current \
    --exclude=/etc/ssh/ssh_host_dsa_key \
    --exclude=/etc/ssh/ssh_host_dsa_key.pub \
    --exclude=/etc/ssh/ssh_host_rsa_key \
    --exclude=/etc/ssh/ssh_host_rsa_key.pub \
    --exclude=/supervise/status \
    --exclude=/tmp/* \
    --exclude=/var/backups/*gz \
    --exclude=/var/log/**/\@* \
    --exclude=/var/log/**/current \
    --exclude=/var/log/dmesg \
    --exclude=/var/run/*pid \
    --exclude=/var/tmp/* \
    --exclude=dhclient.leases \
    --exclude=dhcpd.leases \
    --exclude=known_hosts \
    --exclude=locatedb \
    --exclude=ntp.drift \
    --exclude=proc/* \
    --exclude=random-seed \
    --exclude=utmp \
    --exclude=wtmp \
    $src $dest

you'll need "-essh" and root on both sides to read/create all the uids.

Caveat emperor and you may still have some problems with daemontools
control files being included...
