Rsnapshot  keeps what look like snapshots online with a history
hardlinked where possible (in the history of the same system to save
some space.   I'm not quite sure how much it understands about lvm but
it looks like that's a special case for local use.

Backuppc will give you compression as well, plus will hardlink all
identical content even if found on different targets or in different
locations, so you can keep much more history in the same amount of
space.  And it gives you a nice web interface to monitor and control
everything.
