HP Reference Information Storage System Version 1.6 Administration Guide revision 2 (T3559-90809, September 2007)

Preparing the backup ser ver for disaster recovery
The following steps and procedures d escribe how to restore the backup ser ver (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
very Manager,” in the Tivoli Storage Manager Administrator’s Guide. Those chapters
contain more complete instructions than does this do cument, which is intended as an introduction to
disaster recovery. (See " Tivoli Storage Manager" on page 99 for information about how to obtain
acopyoftheguide.)
Things to back up
In order to protect the backup server, the following information has to be backe d up and stored off-site:
1. Backups 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 TSM configuration, including all of these components:
• A copy of the Volume History File: Volume history information is stored in the database, but
is not available during a database restore. Among other things, this file contains information
about database backups and volumes that have been added, removed, or reused.
• AcopyoftheDeviceConfiguration File: This file contains information 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 general settings for the ser ver. For more
details about these components, please consu lt the TSM Administrator’s Guide, particularly
pages 707 to 709 and pages 721 to 729.
TSM Dis
aster Recovery Manager
The Dis
aster Recovery M anag er (DRM) is a function of the TSM Extended Edition. The DRM generates
arecov
ery plan and automates some of the steps that prepare the server for a disaster and help it
recover afterward.
The recovery plan file is a set of macros and instructions that can be broken down into individual files to
autom
ate the recovery process and guide administrators through it. The file contains the Volume History,
Devic
eConfigu ration, and Server Options files, am ong 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 me dia that is
stored off-site. After the data on the m e dia 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 ser ver for a disaster
The following steps show how to gather all of the necessary data to be able to restore the backup server
and its volumes. Replicate the entire cycle a t least once in order to bec om e familiar with the tasks.
In this example, the RISS system is configured to b ack up smart cell group data. The backup server
contains four tapes; the first one holds the b a ckup of the smar t cell data.
Details and a further explanation of how to automate these tasks can be found in the TSM Administrator’s
Guide, pages 749 and 780.
