I can't quite make the numbers line up, I backup 5 lvs so I'd expect roughly 10 metadata updates per day but it looks closer to 20, but I'm starting to think that this is the problem, and I've hit it because I backup every day and so am constantly having a churn of metadata versions.
Just to close this - it turns out that a lvcreate (at least of a snapshot volume) causes two metadata updates, and likewise the lvremove.
