LVM provides a block level device. However you don't want to back up there
anyway, you'll just end up with corrupt garbage. You need to back up at
the filesystem level unless you're using your LVM LVs for Oracle or
something similar in which case the backup software needs to support that
by putting Oracle or the related application into the correct hot backup
mode before attempting to directly read the LVM data, as well as backing up
the transaction/redo logs.
