Which storage array feature records only changes made to the base volume and keeps an earlier state of the original volume?
A snapshot records only changes made to the base volume and allows an earlier state of the original volume to be recreated. It is more space-efficient compared to a clone, which is a duplicate of an entire volume.
Answer: A is the original volume that is to be copied. Unlike a clone, which is a duplicate of an entire volume, a snapshot only records changes to the base volume (copy-on-writes). This allows an earlier state of the original virtual volume to be recreated by starting with its current state and rolling back all the changes that have been made since the snapshot was created. Snapshots are ordinarily more space efficient than a clone.
