Hello, Every checkpoint represent a complete filesystem at a given time. When a system corruption occurs, is it possible to mount a specified checkpoint (when the system is still clean) as read-write to "time-shift" to the state when the bad thing still not happened. Of course the checkpoints newer than the "time-shift" point will be discarded.
