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