Snapclone A virtual disk that can be manipulated while the data is being copied. Only an
Active member of a virtual disk family can be snapcloned.
The Snapclone, like a snapshot, reflects the contents of the source virtual disk at
a particular point in time. Unlike the snapshot, the Snapclone is an actual clone
of the source virtual disk and immediately becomes an independent Active
member of its own virtual disk family.
snapshot
A temporary virtual disk (Vdisk) that reflects the contents of another virtual disk
at a particular point in time. A snapshot operation is only done on an active
virtual disk. Up to seven snapshots of an active virtual disk can exist at any point.
The active disk and its snapshot constitute a virtual family.
