Built on thin copy technology, 3PAR® Virtual Copy is a reservationless, non-duplicative, copy-on-write software product that allows you to protect and share data from any application, affordably. 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 it never affects peer snapshots.

Other Snapshot Approaches
|
|
Reservationless snapshots. Fine-grained capacity consumed only for changed data.
|
20% to 100% upfront space reservation per copy.
|
|
Thin copy-on-writes. Changed data is never duplicated within a snapshot tree.
|
Fat copy-on-writes. Changed data usually duplicated for every snapshot of a base volume.
|
|
Snapshots of snapshots for fast, flexible sharing of data sets without the need for additional base volumes.
|
Often not available.
|
|
Revert to any snapshot with a single command, at any time.
|
Not easy to revert to any snapshot. May require snapshot to be copied to a new base volume.

Other Snapshot Approaches
|
|
Hundreds of snapshots per volume. Affordable CDP-like rapid application recovery from multiple points in time.
|
Few snapshots per volume lead to brief or sparse snapshot histories.
|
|
Thin copy-on-write technology and massive parallelism mean little to no performance impact.
|
Poor snapshot performance and negative impact on production volumes.
|
|
Freely delete snapshots without affecting peer snapshots.
|
Deleting a snapshot may impact peer snapshots.
