In a few words, if your hardware is high-quality, i.e. reliable enough 
so you don't expect problems, LVM adds important functionality and 
flexibility on servers.

In any case, the need for good backups should not be overlooked. For 
example, mondorescue allows both full and incremental backups, using LVM 
or not.
