HP StorageWorks Reference Information Storage System V1.5 Administrator Guide (T3559-96044, June 2006)

Preparing the backup server for disaster recovery
The following steps a nd procedures describe how to restore the backup server (not the entire RISS system)
in case the server itself or storage volumes are lost or destroyed. Restoring the backup server involves
performing backups of the primary storage pools and the backup server database and configuration,
and then storing this data off-site.
Familiarize yourself with chapter 24, “Protecting and Recovering Your Server,” and chapter 25, “Using
Disaster Reco
ver y Manager,” in the Tivoli Storage Manager Administrator’s Guide. Those chapters
containmorecompleteinstructionsthandoesthisdocument,whichisintendedasanintroductionto

Things to back up
In order to protect the backup server, the following information has to be backed up and stored off-site:
1. Ba ckups of storage pools, so that entire storage pools or individua l volumes can be recovered.
2. A backup of the TSM database and recovery log. The database contains information about
the client data that is stored in storage pools. The recovery log contains changes that have
been made to the database.
3. A backup of the TS M configuration, including all of these components:
• AcopyoftheVolumeHistoryFile:Volumehistoryinformationisstoredinthedatabase,but
is not available during a database restore. Among other things, this file contains information
about database backups and volumes tha t have been added, removed, or reused.
• A copy of the Device Configuration File: This file c ontains i nformation that is required to read
backup data, such as library, path, device, and device class definitions.
• A copy of the Server Options File: This file contains g eneral settings for the ser ver. For more
details about these components, please consult the TSM Administrator’s G uide, particularly
pages 707 to 709 and pages 721 to 729.
TSM Dis
aster Recovery Manager
The Dis
aster Recovery Manager (DRM) is a function of the TSM Extended Edition. The D R M generates
arecov
ery plan and automates some of the steps that prepare the server for a disaster and help it
recover afterward.
Therecoveryplanfileisasetofmacrosandinstructionsthatcanbebrokendownintoindividualfilesto
autom
ate the recovery process and guide administrators through it. The file contains the Volume History,
Devic
e Configuration, and Server Options files, among others.
Perfo
rm frequent (for example, daily) backups of the storage pools and the database. Then generate
the r
ecovery plan file and store this data off-site. The DRM also helps to keep track of the media that is
stored off-site. After the data on the media has expired, the media can be brought on-site again and
used in the next backup cycle.
The f
ollowing example provides a backup scenario.
Example: Preparing the backup server for a disaster
The following steps show how to gather all of the necessary data to b e able to restore the b ackup ser ver
and its volumes. Replicate the entire cycle at least once in order to become familiar with the tasks.
In this example, the RISS system is configured to back up smart cell group data. The backup server
contains four tapes; the first one holds the backup of the smart cell data.
Details and a further explanation of ho w to automate these tasks can be found in the TSM Administrator’s
Guide, pages 749 and 780.
