[OS X TeX] backing up /usr (and MacTeX)

I can feel the pain (got lots of motherboard and HD-replacements over
time – and several portable macs) and I cannot emphasize the necessity
for backups, but since you are in London, why not buy a external HD
with a Firewire (AND USB-)-connection, they cannot be that expensive.
Just clone your internal HD to it and then try to repair the internal
SD is really cheap and very reliably (and the smart cloning is really
worth it, considering the time saved; basic operation (erase external
drive, then copy/clone) is free. CarbonCopyColoner has acquired a
smart-clonig-alike feature, so this wouzld be an option as well.
Setting it up is just a teeny bit more elaborate than with SD.
Having done that I'd erasing the internal drive (AFTER verifying that
the bootable backup on the external HD works alright), reinstall the
systems software and clone back… You might use migration assistant if
you are on Leopard but this dies NOT cover /usr/etc.
Hope that helps,
