Nux, I understand this - but a question for you - you have i.e. 3 volumes attached to a VM - how do you snapshot those and make sure they are snapshoted in the EXACT same moment, to preserve data integrity of the data inside VM - you have i.e. database files on 1 volume, database logs on another.
This is a reall question, not kidding ? What I know, you can turnoff VM, and then snapshot one by one - but this is not the goal of the snapshotting... ?
