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

Common limitations
• Maximum 512 shadow copies per volume are allowed. The number of shadow
copies per volume is limited by system resources.
• To run a VSS integration backup, the writer’s data must be on an NTFS filesystem.
For hardware providers, this is not required.
• The VSS integration backup of writers which store their data on network shared
volumes is not supported.
• The Data Protector Microsoft VSS integration does not provide any restore method
for writers requesting a custom restore method. These writers are by default not
presented by Data Protector.
If a writer specifies a custom restore method, it is only possible to restore the
writer's data as plain files using the Data Protector functionality. You can perform
the custom restore manually. Refer to the writers documentation for additional
information on the restore methods.
• Microsoft Exchange Server 2007 Standby Continuous Replication (SCR) is not
supported
• Preview is only possible for VSS filesystem backup sessions.
Configuring the integration
The Data Protector Microsoft Volume Shadow Copy integration by itself does not
require any configuration steps neither on the Data Protector nor on the application
side.
VSS writers are either a part of Windows operating system or delivered with
applications. Data Protector automatically detects writers when the VSS backup
specification is created and registers them.
You may check which writers and providers are installed and registered on your
system using the following Windows operating system command:
• For a list of writers: VSSadmin list writers
• For a list of VSS providers: VSSadmin list providers
Microsoft Exchange Server writer specific configuration
A backup of the Microsoft Exchange database is considered successful only when
consistency check of the replicated data files succeeds.
