Backing up my new Mac?

[Feek]

I'm just working out my backup plans for my new Mac Pro - I know this isn't true data redundancy but it should suit me.

My system consists of the following:

320Gb Boot drive - OS and Applications
1Tb internal drive - /home and user data
500Gb internal drive
500Gb external USB drive

I plan to use Time Machine to back up the boot drive which is the OS and applications along with the 1Tb drive onto the internal 500Gb drive. I appreciate that this doesn't quite calculate in terms of space but I'm nowhere near full yet so it's a starting point until I pick up a bigger Time Machine drive.

I'm also going to set up Carbon Copy Cloner to backup the 320Gb boot/application drive to the external USB drive so that if I have a boot drive failure then I should be able to get back up and running very quickly.


How does this sound as a basic way of doing things? I'm effectively backing up the os/applications drive to two different destinations (although both are either in or next to the system box) and the home and user data to an internal drive with Time Machine. It should be remembered that this isn't a business and data loss will be inconvenient at worst.


Incidentally, if I replace my boot drive with a faster one, will CCC be able to do a complete clone from the existing drive to the new one while it's still mounted and allow the new drive to be bootable?
