Thanks  to Rolf and David who made suggestions regarding backup  
strategies both on- and off-list.
In fact I use Intego Backup (the X4 version - don't get me  
started...) for backups but my firewire HD is deep in Germany while I  
am sitting here in London. So I can not make a clone capable of  
booting. Moreover, now that Apple is moving away from firewire (WHY  
did they do that to me?!) that might not be the best storage option  
Anyway, not a big deal... this iBook will eventually (or rather in  
the near future) break down completely so I am careful not to keep  
important data on my HD and keep small selected backups on a USB  
storage device. Unfortunately, last time I reinstalled from scratch  
and tried to save a clone on that USB-HD I ran into major problems  
and had to reinstall 5 times.
Long story, short conclusion: my current approach is to maintain  
backups of the really important stuff on my HD (my customized MacTeX  
distro being part of that). Therefore it would be nice to know if I  
can just create an archive of /usr and move that to the USB storage  
device or if this would lead to problems when trying to revert to  
that backup.
