I use ext4.   The advantage is journaling, which as I understand it 
reduces the chance of loss in case of power failure or the like. If 
you're using rsync, it will correct any prior bad copies (I think) at 
the next run.

On the basis that 1 back-up is better than none, can you cope with 2 
external devices?   As somebody else said in another topic, (approx) as 
long as you have a well tested spare lying around for when the main 
target fails.   Somebody put it more like this many years ago: There are 
2 kinds of drives around; those that have failed, and those that are 
going to fail.  Thankfully failure is getting rarer.
