After you once complete this procedure, the VSS and VDS providers are ready to be
used for zero downtime backup and instant recovery.
Configuring the VSS hardware provider for Disk Array XP
Before running ZDB sessions, open the HP StorageWorks XP VSS Hardware Provider
Configuration Utility and choose the configuration mode for your backups:
VSS
Compliant Mode
or
Resync Mode
.
NOTE:
Changing the modes between backup sessions may have an impact on restore. For
details, see “
HP StorageWorks Disk Array XP considerations ” on page 396.
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 is 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
If any file or folder on the volume does not belong to the component, the ZDB to
disk or instant recovery fails.
