This is an excellent tutorial on LVM.


Are you planning to join it to an existing Volume Group and then create 
a LV on it for backup? My preference would be to keep things simple and 
to aid recovery in the future, maybe just format the disk ext3 for 
backup. Then it is easy to plug into another box for recovery. But, I'm 
just guessing how you plan to use it.
