The backup method works but is measurably slower in my tests than than the plain copy under a lock; the benefit should be better concurrency. I don't know which is better: the faster hotcopy that blocks writers or the slower hotcopy that allows writers to progress? At the moment it's a compile time decision based on the version of SQLite but that's not a good way to decide whether we should be using this feature. I think it's too obscure to make it configurable on a per-repository basis so I don't really know what we should do. -- Philip
