While something is clearly wrong, this isn't it. Each snapshot is its
own btree, and you said there is little churn each day, so they aren't
getting significantly larger over time. Each snapshot is tracked in the
tree of tree roots, so technically it is growing each time you take a
snapshot, but 60 items is nothing.
