Hi spf62,
Well, snapshot is much faster when it is done with the machine off, revert to the snapshot is best to be done with the machine switched off to avoid mistakes, because end up getting arrested services. and often the snapshot failed before reaching 100%.
Well that needs to be told what happens in many companies where step is Snapshot backup is not.
Snapshot is used to test, implement some tool or some application.
Should not accumulate because after snapshot becomes a mess and in some cases difficult to return, only making them commit.
