Rsync utilization every 5 seconds

[Todd_Joseph at groove.net]

If you insist on every 5 seconds:

--------------------------
#!/bin/sh

while :
do           rsync [opts] SRC DEST
      sleep 5
done

Every 5 seconds seems a bit excessive in terms of CPU utilization and
network bandwidth.  Are you trying to ensure close-to-real-time
synchronization by doing this?  If you have the ability to run processes on
the source machine, perhaps running a process that monitors the source
directory for changes and then runs rsync when changes occur would reduce
overhead?

Others with more experience may have better ideas.
