HP Application Recovery Manager software Integration guide (March 2008)

makes ZDB and IR capabilities suitable for high-availability systems and mission-critical
applications.
Application Recovery Manager ZDB and IR techniques utilize snapshot technologies
of disk-based arrays. The following are the basic principles behind ZDB and IR:
• Create, at high speed, a copy of the data to be backed up and then perform
backup operations on the copy, rather than on the original data.
• Restore a backup copy of data, held on the array, to its original location on the
array to facilitate high-speed recovery.
VSS backup types
Application Recovery Manager supports only full backups.
The following backup types are available with the Application Recovery Manager
VSS integration:
• Local VSS backup
The shadow copy is backed up from the application system.
• Transportable backup
Instead of presenting the volume shadow copies to the application system they
are presented to an alternate system thus reducing the impact of post backup
activities, such as consistency checking. It also provides the option to mount the
backup replicas on a backup system.
Instant recovery with VSS
Instant recovery is a process in which a replica, produced by a VSS hardware
provider, is used to restore the contents of the source volumes to their states at the
time at which the replica was created. This process consists of the preparation and
actual recovery of data and, optionally, some post-restore actions that make that
data ready for use.
The Application Recovery Manager internal database (IDB) keeps track of data, such
as, which replicas from which system are kept on a particular disk array. The IDB
provides fast and convenient access to the data to be recovered.
Advanced features of Application Recovery Manager instant recovery:
• Ability to restore on different levels: session or object
• Ability to automatically start post-recovery scripts
