Re: How's different snapshot and snapclone?
Snapshot = point in time representation of data (all the data is not copied, only the data that it changed after the snapshot is taken).
Snapclone = bit for bit copy of a virtual disk.
MirrorCopy = Ongoing local replication of a virtual disk, until it is broken at which point the "copy" becomes it's own virtual disk. (I could have this a little wrong in some ways. I don't do much with MirrorCopy, but will check tomorrow when I am on an EVA.)
Snapshot generally only takes up the necessary space to hold the "changed" data.
Snapclone will cost the full amount of storage as the original virtual disk.

Re: How's different snapshot and snapclone?
Hi Nataris,
Our fellow ITRC'ans have already explained a lot. Just to add to that;
> Snapshot's are solely dependent on the Master volume. (if the Source volume fails you could not restore, no matter how many snapshots you have.
> Snapclones will be totally independent once the job is Complete. So even if the parent volume failed, you could have the volume available.
