  Yes. But can you undo single operations even as non-root user?

    You don't have to be root to read snapshots. It would be nice if every fs operation was a micro-snapshot (like an undo tree), but in practice frequent scheduled snapshots work pretty well. (If it didn't exist 15 minutes ago, you can probably get it back)
