AIUI the OP was mounting an (external?) drive partition for use as a 
destination for backups.  Prior to upgrading to Testing, the root 
partition was /dev/sda1 (no LVM?) and the backup partition was /dev/sdb1 
(no LVM?).  After upgrading to Testing, the root partition is /dev/sdb1 
and the backup partition device node is unknown.  The OP was confused by 
the changed root partition device node.


Please describe how LVM would help in this situation.
