FYI,
Data Protector supports ZDB/IR with 3PAR which is Zero Downtime Backup and Instant Recovery using VSS for consistency. Basically the ZDB/IR feature integrates directly with 3PAR to provide application aware snapshots. These can be retained and rotated internally on the array, an entire volume can be instantly restored from snapshot, or they can also be mounted for individual item recovery. Also snapshots can be retained but streamed to tape / disk device or both for replication or longer term retention.
From memory ZDB is licensed per TB protected, so if you have to protect 10TB's of production data in this manner, regardless of the number of copies retained you would need a single 10TB license. Don't have links to the latest version, DP 8.x I think, but here's a white paper for an older version covering similar.
