I'm using TM for quite a long time know, and everything was working perfectly
I just upgrade my MBP 15" and I would like to upgrade my backup system as well

My actual configuration in a 64Gb internal SSD (for OS), a 500Gb internal HDD (100Gb partition for TM backup of my SSD + 400Gb partition for files) and a 1Tb external HDD

I would like to have my SSD backup on my internal HDD 100Gb partition AND my internal HDD 400Gb partition backup on my external HDD (1Tb)

it would mean to have 2 completely independent TM backup using 4 partition.
is there a way to make this work?
I asked my friend google, but he did'nt had any answer for me

Thanks in advance
