HP Data Protector 6.2 software integration with HP 3PAR Storage System

5
• 3PAR InForm Management Console is installed on one of the servers and manages the HP 3PAR
Storage System.
Once the backup session is started, Data Protector will resolve the volumes involved in the backup.
During this phase, Data Protector finds out on which storage volumes the selected objects are located.
Finally, it requests the creation of a snapshot for each of those volumes by using 3PAR Hardware
Provider. This copy is a replica or a virtual copy snapshot in 3PAR terms. The 3PAR Storage System
maintains integrity of the data on the snapshots using copy-on-write technology. In Figure
3, creating a
virtual copy is shown by the red line.
Figure 3: Creation of Virtual Copy Snapshot
After it is created, the snapshot is presented to the backup host. The following screenshot shows, in
the 3PAR InForm Management Console, the VSS-created Virtual Copy. Note that VSS created
snapshots are named starting with vss. There are two snapshots with the same ID number. One has
ro in its name to indicate that this snapshot is a read-only one. The second one has rw in its name to
indicate that this snapshot is a read-write one and can be exported or presented to the server.
