Internal Database Maintenance
Overview
Chapter 572
Overview
The IDB is an internal database, located on the Cell Manager that keeps
information regarding which data is backed up, on which disks it resides,
the result of backup and recovery sessions, and which disk arrays are
configured.
What is the IDB
used for?
The information stored in the IDB enables the following:
• Fast and convenient restore
• You are able to browse sessions to be restored.
• Backup management
• You can verify the result of backup sessions.
For more information, see the online Help index: “IDB”
Configuring the IDB Backup
An essential part of the IDB configuration is configuring the backup of
the IDB itself. Once the IDB backup is performed regularly, the most
important preparation for recovery in case of a disaster is done. The IDB
recovery is essential for recovery of other backed up data in case of the
Cell Manager crash.
Consider the following when configuring the IDB backup:
• Schedule the IDB backup to be performed once per day. This ensures
that you always have an almost up-to-date backup of the IDB.
• Do not overwrite the previous IDB backup with the new one (keeping
several copies is suggested).
• If possible, store the IDB backups on more fault tolerant system.
The internal databases and configuration must be backed up separately
and not by using the Filesystem backup because Application Recovery
Manager must be stopped before you can back up the internal databases
and configuration and restarted after the successful backup. Application
Recovery Manager offers the dbtool.pl utility to back up the database
and configuration to a safe location.
