My multi-user backup solution

[Eagle]

Greetings, all.

As you may remember, a few weeks ago I started looking for a good 
multi-user backup solution for OS X, but didn't find one.  I wanted 
something that:
- could be automated,
- supported resource forks,
- supported both full and incremental backups,
- supported multiple backup sets, and
- supports the multi-user aspect of OS X (i.e. something that preserves 
file ownership and permissions).

So, I decided to write my own solution that encompasses all of the 
features listed above.  My solution requires hfspax for the actual 
archiving, but what it provides is a completely automated solution 
(well, if you configure it properly and also add it to crontab) that 
can be left to run unattended.  Only slightly more scripting would be 
required to actually burn the resultant .pax archives to a CD or DVD; I 
will likely add that in the near future as it is a feature that I want 
to have.

There is one other feature I had wanted, but it is not in my script.  
That is support for excludes.  (e.g. "do not include my iPhoto and 
iTunes libraries")  Perhaps I will add this later.

If you wish, try out my script.  It can be downloaded at:

Documentation is in the script itself.

As it uses hfspax for the archiving, restoring is done through the 
hfspax command line.  Also, I wouldn't yet recommend using it for 
mission-critical backups, because further testing will be required, but 
so far it looks really good.

Enjoy.  Comments and other feedback will be welcomed.
