[luau] Next up, back up

nifty, but don't you think learning to tarball will be quicker and more 
useful to Peter?

give him the old-reliable, tried and true methods like 
http://www.faqs.org/docs/securing/chap29sec306.html  see how much simpler 
that script is than the rsync script?  Pretty much the same features.

Remember the less services you use, the better (for security mostly). 
Personnally I refuse to run ftpd & rsyncd on any of my servers.  All that 
rsync crap is ment for mirroring and developers.  The same people using 
rcp I guess.

I can get the same rsync behavior from RH's ftpcopy package for updating 
of new and modified files on any existing FTP server.  After-all isn't 
rsync just FTP used a diffferent way on a different port?

My favorite of all backup methods (above and beyond redundant raid 
arrays, off-site storage, and rotating, removable storage) is the 
evolving and ever-improving snapshot method using rsync

http://www.mikerubel.org/computers/rsync_snapshots/

I noticed it a while back when googling, and the documentation just 
gets better.  If one knows little about archiving, the whole thing is 
written well enough to be educational.
