Where do you get that idea?  What do you mean by, "aren't considered 
reliable"?

You didn't think I meant to take a snapshot and call it a day, did you?  No, 
absolutely not.  You create a snapshot volume then mount that and back up the 
read only data in it.  The goal is to get a backup you can restore from.

You didn't think I was talking about using writable snapshots with LVM for 
basing multiple Xen VMs on, did you?  Well, sorry for the confusion it that's 
the case.  I was talking about read-only LVM snapshot LVs for doing backups.

Hope that clarifies things a bit.
