You should back up data before installing new software on the off chance that the software deletes a bunch of stuff, infects your computer with a virus, etc. Basically, you do it so that if you loose anything, you can get it back.
If you use iTunes then your Ipod should have backed up all your applications onto your account. Therefore when you are next on your iTunes add your back up data to your ipod.
Banking Institutions back-up their data 'live'. Every time the computer carries out a transaction - it performs an incremental back-up. This means that - it only backs-up accounts that have had new transactions applied to them.
All back up methods are a great idea for saving data. You should always create a data back up. So having 2 data disc is always a great idea and peace of mind that your pictures will always be around.

Unfortunately, there is no way to back up your data.
