Built on thin copy technology, HP 3PAR Virtual Copy is a reservationless, non-duplicative, copy-onwrite software product that allows you to protect and share data from any application. Snapshots are available on demand, instantly, in read-only and / or read-write form. With Virtual Copy, snapshots are reservationless because capacity is never reserved up-front and non-duplicative since changed data is never duplicated within the snapshot tree. Coupled with consistency groups and support for hundreds of snapshots per base volume, Virtual Copy efficiency delivers affordable, CDP-like rapid application recovery from multiple points in time. With a single command, you can revert a base volume to any selected snapshot – without impacting other snapshots in the tree. And when you delete a snapshot, this never affects peer snapshots.
