Hi, In this thread dated 2013-10-15: https://marc.info/?l=linux-nilfs&m=138184919111358&w=2 It briefly mentioned NILFS's ability to rollback into previous file system states: "Of course, NILFS2 has such very powerful concept as checkpoint/snapshot is based on Copy-On-Write (COW) policy. Potentially it gives opportunity to rollback into \previous file system states" Can someone show me how this is done? Thanks!
