Modified SnapVX point-in-time copies

Host writes to a linked target device do not change the point-in-time copy, so only the linked target device contains a modified point-in-time copy. To copy a modified point-in-time copy back the original source device, establish a snapshot from the target device and then create a Copy mode link of that snapshot back to the source device.

The figure below shows an example of copying a modified point-in-time copy back to the source by linking (in Copy mode) a snapshot of the linked target back to the source device.
