Create incremental backups using an rsync shell script
Authored by: Ross T on Mar 22, '07 11:52:06AM
I wish to be respectful to the poster, but there seems to be no end of backup scripts offered by users who assure us that "it works for me." To my knowledge, only one user has actually investigated exactly what the various backup solutions do and more important fail to do. May I suggest that anyone proposing a backup solution read these two articles first:
<a>http://blog.plasticsfuture.org/2006/03/05/the-state-of-backup-and-cloning-tools-under-mac-os-x/</a>;
<a>http://blog.plasticsfuture.org/2006/04/23/mac-backup-software-harmful/</a>;
The author's point is that unless you know what your backup system does to BSD flags, file ownership, permissions, resource forks, HFS+ extended attributes, and ACLs, then you can't realy claim that it works.

My nightly script runs on a server to wake up sleeping Macs and tell them to run their local backup script. It incidentally tells them to run their periodic maintenance scripts while they're awake. I used to use rsync but found it so buggy on Tiger that I switched to a modified version of psync. I still have concerns, though, which is why I do not recommend my own script, although, as the saying goes, it works for me.

Agreed -- That was the very first link!
