Backing-up OSCAR 3 Nodes by Hand

Just do this on the computing node:
rsync -avxHS --numeric-ids --delete --exclude 'lost+found' --exclude '/tmp/*' --exclude '/var/spool/clientmqueue/*' --exclude '/var/spool/pbs/aux/*' --exclude '/var/spool/pbs/mom_logs/*' --exclude '/var/spool/pbs/mom_priv/jobs/*' --exclude '/var/spool/pbs/spool/*' --exclude '/var/spool/pbs/undelivered/*' --exclude '*.pid' --exclude '*.lock' --exclude 'swapfile0' / 10.0.0.254:/usr/cluster/nodes/oscar3/root/
and also this:
rsync -avxHS --numeric-ids --delete --exclude 'lost+found' --delete-excluded /boot/ 10.0.0.254:/usr/cluster/nodes/oscar3/boot/
Done. (Update: please be careful about the directories that has been ignored... I don't trust the exclude expression.)
