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

used for the mirror replica in that session. As a consequence, a new backup
session will not have a free MU number available to create a new mirror and the
session will fail.
ZDB limitations
• For VSS transportable backups, the hardware providers for the volumes included
are required.
• Dynamic disks (Logical Disk Manager partitions) can only be backed up with
software providers.
• GPT disks are not supported for backup and instant recovery purposes.
Instant recovery limitations
• Only writers that have data on volumes managed by VDS hardware providers
can be restored using the instant recovery functionality.
• Not all VSS writers supported by Data Protector can be used with the instant
recovery functionality. For a list of the VSS writers that support the instant recovery
functionality, refer to the latest support matrices at http://www.hp.com/support/
manuals.
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. However, some applications such as Microsoft Exchange Server may require
additional configuration steps. For details, see the appropriate sections. You must
also configure the VSS and VDS hardware providers.
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
• For instant recovery enabled backups, VDS hardware providers should be present
in the list of installed software. Check Control Panel > Add/Remove Programs.
For instant recovery enabled backups, only non-system writers are supported, because
instant recovery cannot be performed on a system disk.
