Question<BR></FONT><BR></DIV>

<DIV><SPAN class=250113717-10032004><FONT face=Arial size=2>I have seen some
stuff referring to rsync with backing up servers. Can anyone tell me how
this works? Can I use this to make an exact copy of my running
production server to a backup server of either equal or lesser hardware.
Idea being that upon hardware failure of the production server I would have an
up to date backup (or possibly only 24hrs behind) to swap in and run as a
temporary production server until the main hardware was repaired. Let me
know if this is feasible (maybe I need identical hardware) and if so where to
start (what commands to issue). Ideally I would like to have the two
machines running a scheduled periodic backup that was automatic and did not
require any manual intervention.</FONT></SPAN></DIV>
