Microsoft Hyper-V Vss Writer Restore Specifics; Restore From A Physical Cluster Node; Instant Recovery - HP Data Protector A.06.11 Integration Manual

• If an RSG for the storage group you are restoring already exists on some system
other than the target system, the RSG is not automatically deleted and so the
creation of an RSG on the target system fails. In this case, you should manually
delete the RSG on the other system.

Microsoft Hyper-V VSS writer restore specifics

Restore of Hyper-V writer data is possible to the original or to a different location.
During a restore to a different location, the Hyper-V writer checks whether a virtual
machine with the same identity already exists on the system. If it does, the Hyper-V
writer removes the virtual machine from the system before restore and imports the
restored virtual machine. If such a virtual machine does not exist on the system, it
means that a restore session to this system is in progress or that the virtual machine
was already removed. It is possible to perform restore or instant recovery of Hyper-V
virtual machines to any Hyper-V system, which has a Hyper-V writer.

Restore from a physical cluster node

ZDB to tape sessions from a physical cluster node can be restored to any cluster node
using a standard restore procedure. To successfully restore such a session to a cluster
node, perform the following steps:
1. Delete the cluster group of the virtual machine to be restored using Failover
Cluster Management.
2. Perform standard restore of the virtual machine on the cluster node where the
virtual machine disk is active. For the standard restore procedure, see
procedure" on page 380.
3. Re-create the virtual machine cluster group using Failover Cluster Management.

Instant recovery

For general information and concepts on instant recovery, see the HP Data Protector
zero downtime backup concepts guide and HP Data Protector zero downtime backup
administrator's guide.
The Data Protector VSS integration provides instant recovery of MSDE Writer,
SqlServer Writer, Microsoft Exchange Server 2003 Writer, and Microsoft Exchange
Server 2007 Writer.
You can selectively restore separate writer's components only if they reside on separate
target volumes. Instant recovery of separate components also requires that the target
volumes with components data should not contain any other data. If you do not select
