Idb Growth And Performance; Key Idb Growth And Performance Factors - HP B6960-96035 Concepts Manual

IDB maintenance
Once you configure the IDB, its maintenance is reduced to a minimum, mainly acting
on notifications and reports.
IDB recovery
An IDB recovery is needed if some of the IDB files are missing or corrupted. The
recovery procedure depends on the level of corruption.
For detailed information, see the online Help index: "IDB, recovery".

IDB growth and performance

For proper IDB configuration and maintenance it is necessary to understand the key
factors that influence the IDB growth and performance, as well as the key tunable
parameters that you can adapt to your needs, and thus handle the growth and
performance of the IDB as efficiently as possible.

Key IDB growth and performance factors

The key factors for IDB growth and performance are the following:
• Logging level settings Logging level defines the amount of detail written to the
IDB during backup. The more detailed logging level you use, the greater influence
it has on the IDB. For details, see
parameters" on page 198.
• Catalog protection settings Catalog protection determines how long the information
about backed up data is available in the IDB. The longer period of catalog
protection you set, the greater influence it has on the IDB. For details, see
growth and performance: key tunable
• Number of backed up files Data Protector keeps track of each file and each
version of that file. Different backup types impact the IDB differently. For
information on backup types, see
• Number of backups
The more often you perform a backup, the more information is stored in the IDB.
• Filesystem dynamics The number of files created and removed between backups
can have a significant impact on the growth of the filenames part of the IDB. The
Report on System Dynamics gives you information about the system
dynamics. You can avoid the IDB growth due to filesystem dynamics by using the
Log Directories logging level.
