How would you set a cron to run every 30 seconds? Otherwise it could work

Re: Can rsync monitor a file
what about scripts running every 30 seconds on each machine,
thats lighter then rsync just to compare..
---- Server1 ----
ls -lR /* > ~/files1
scp files1 SERVER2:~
---- Server2 ----
ls -lR /* > ~/files2
(do a diff command here on files1 vs. files2)
(if different, then run rsync -u)
