HP Data Protector A.06.00 additional writers and HP StorageWorks Disk Array XP support for Microsoft Volume Shadow Copy Service integration

In cases where the application and backup systems are the same, ensure that the
VSS/VDS hardware provider is configured for the same Command View on both
EVAs. Otherwise, rotation and deletion of old replicas from other EVA disk array is
not possible.
If a failover occurs, the backup using the same backup specification as before failover
will fail, since the backup system is no longer connected to the disk array where the
new replicas reside. In this case, you can:
• Perform manual failover to restore the same disk array connectivity configuration
as before the first failover.
• Create a new backup specification with the new backup objects specified.
• Establish a connection between the backup system and the disk array where the
new replicas reside.
For restore limitations in this scenario, see “Limitations” on page 121.
Configuration check
With instant recovery, it is possible to selectively restore separate writer’s components
if they reside on separate source volumes. Instant recovery of separate components
also requires that the volumes with components data should not contain any other
data. The configuration check detects, whether there are more than one component
on the volume and whether there is any other data besides the component’s data.
At backup time, Data Protector can check whether the individual components can
be selectively restored using the instant recovery functionality. At instant recovery
time, Data Protector can check whether the data required for the components restore
is available.
In case of the Microsoft Exchange Server Writer, it is checked, whether the whole
storage group should be restored, or whether the separate database stores can be
restored individually. In case of the MSDE Writer, it is checked, whether the user,
system, and log files are on separate volumes.
If the check fails for a component during the backup, you will not be able to select
this component for the instant recovery, you will need to recover all writer components.
If the check fails during the instant recovery, the instant recovery session will fail.
Configuration check modes
You can select between three configuration check modes:
• Strict
