Best way to backup Firmware

Because I'm having some problem with actual firmware releases when using rpi-update I'm searching for a solution to backup the complete firmware with kernel and modules and everything else related to firmware. If the new firmware has a problem, I like to restore the old.
Anyone an idea how to make a script doing this?

have a look at the rpi-update script...
or don't use rpi-update and just use apt-get upgrade

Sorry, but I looked at the script and did not found an answer. I simply need to know, which files exactly are changed by rpi-update!

Files in
/boot
/lib/modules/
/opt/vc
are changed by rpi-update.
Note: that rpi-update now allows downgrading.
sudo rpi-update 192 <hash>
where you can find the hashes here:
https://github.com/Hexxeh/rpi-firmware/commits/master
e.g. if you want to revert to September 26th firmware:
sudo rpi-update 192 d6b57
should do it (you only need to type in enough of hash to be unique).

Hi Dom,
Thx a lot, that's exactly the information I need!
