LVM is not frowned upon. LVM used as a way to name/have a bunch of 
partitions is quite stable.   using lvm2 writable snapshots to create CoW 
disks is rather iffy- (which I bet is what the original poster was talking 
about)
I have not heard of recent problems using _read only_ lvm snapshots to 
take backups, so that part is relitively safe.  Note- there is a big 
difference between read-only and read-write snapshots.  read-write 
snapshots are much more complex to implement.
