Thanks. That's a critical detail to know.


A few follow-on questions... Are taking snapshots:


"atomic"?

Do they hold up or lock out other disk activity?

Is there an overhead to keeping many snapshots other than the storage
any changed files take?

Can we now consider making and deleting snapshots a "debugged stable
feature"?


Thanks,
Martin
