• Only those local backup devices are supported, that can be installed by Windows
during OS installation (no additional drivers are required).
Preparation
See also “Planning” on page 33, for the general preparation procedure for all disaster
recovery methods before completing the steps listed in this section. See also
“Advanced recovery tasks” on page 96 in order to prepare for disaster recovery.
IMPORTANT:
Prepare for disaster recovery
before
a disaster occurs.
Prerequisites
• A full client backup (including the configuration) is a prerequisite for successful
ASR. See the online Help index: “backup, Windows specific” and “backup,
configuration”.
In case of Microsoft Cluster Server, consistent backup includes (in the same backup
session):
• all nodes
• administrative virtual server (defined by the administrator)
• if Data Protector is configured as a cluster aware application, Cell Manager
virtual server and IDB.
See “Restoring the Microsoft Cluster Server specifics” on page 96 for details.
After you performed the full client backup, prepare an ASR set. An ASR set is a
collection of files stored on three diskettes (for 32-bit systems), four diskettes (for
AMD64/Intel EM64T systems), or six diskettes (for Itanium systems), required for
proper reconfiguration of the replacement disk (disk partitioning and logical volume
configuration) and automatic recovery of the original system configuration and the
user data that was backed up during the full client backup. These files are stored as
an ASR archive file on the Cell Manager in the directory
Data_Protector_program_data\Config\server\dr\asr (Windows Server
2008),Data_Protector_home\Config\server\dr\asr (other Windows
systems), or /etc/opt/omni/server/dr/asr/ (UNIX systems), as well as on
the backup medium. After a disaster occurs, ASR archive file is extracted to three
diskettes (for 32-bit systems), four diskettes (for AMD64/Intel EM64T systems), or six
diskettes (for Itanium systems). You need these diskettes to perform ASR.
