Last day i try to take backup of the volumes using snapshot feature available. I have following queries regarding the snapshot working. After the snapshot is taken is there any way to update the contents (COMMIT) of the same snapshot with the changed contents in the share in a future point of time. Also is there any feature like ROLLBACK to revert back the volume content with the contents of the nth snapshot. As per now i have to store multiple snapshots for every changes happening in the volume, which is almost like wasting a hell lot of space. If anyone put light on these and let me know where to refer to get more details on this will be highly appreciable. Thanks in advance. regards, Rahul
