(both customized time and at the point of epoch change) - node-wide data sharing for snapshot objects with the same content. so snapshoting is very cheap operation. - support 'collie checkout epoch' to restore fully to the state of history epoch and customized time. - differential data change between subsequent epoches (for faster nested recovery, that node failure happens at recovery stage) - auto checksumed snapshot objects - no stale objects that are found in current implementation, that will waste storage a lot.
