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

Microsoft Exchange Server 2007 writer concepts
This section gives details of additional features that Microsoft Exchange Server 2007
supports.
Backup
Microsoft Exchange Server 2007 offers two models of replication for data protection
that are supported by Data Protector.
• Local Continuous Replication (LCR)
With LCR, you can create and maintain an exact copy (LCR copy) of databases
in a storage group. LCR copies are used in the event of data corruption, since
you can switch the Exchange server to use LCR copies in only a few seconds. If
an LCR copy is used for backup and is located on a different disk from the original
data, the load on a production database is minimal.
• Cluster Continuous Replication (CCR)
CCR has the same characteristics as LCR. The only difference is that in the CCR
environment, databases and transaction logs are replicated to separate servers.
Therefore, CCR copies can be used for disaster recovery. You can perform VSS
backups on the passive Exchange Server node where the CCR copy is located
and thus reduce the load on the active node.
The replicated storage groups are represented as a new Exchange Server writer
instance, Exchange Replication Service. They are backed up in the same way as
original or production storage groups.
Restore
With Microsoft Exchange Server 2007 writer, you can restore your data not only to
the original location (from which the backup was performed) but also to a different
location. You can restore:
• A whole storage group
• A single store
In both cases the respective LCR or CCR copies can also be restored.
You can restore data to:
• The original storage group
• A different storage group
