Abstract
A method of creating point-in-time views of data on a disk involves initiating from a host at least one session of writing data to a disk. For each session, an entry is created and stored on an array on the disk. The sessions are assigned unique IDs to each, and provide indications where data for a particular session may be found on the disk.
