Reducing the IDB Growth
You can reduce the growth of the IDB by reducing the logging level and
catalog protection settings of your backup specifications. These actions
do not influence the current size of the IDB, but they do influence its
future growth.
The effect of reducing the logging level is a reduction in browse comfort
at restore time.
The effect of reducing the catalog protection is that browsing is not
possible for some restores (namely of those backups that have exceeded
the catalog protection).
Refer to the HP OpenView Storage Data Protector Concepts Guide for
information on key factors and tunable parameters for IDB growth and
performance, as well as for usage recommendations.
How to Reduce the
IDB Growth
Modify the backup specifications by changing the logging level and
catalog protection settings using the Data Protector Backup context in
the Data Protector Manager. See Figure 9-6. For detailed steps, refer
to the online Help index keyword “reducing IDB growth”.
By reducing the logging level settings for a backup specification, you
reduce the amount of data (files/directories) that will be stored in the
IDB (Log all -> Log files -> Log directories -> No log).
By reducing the catalog protection, you reduce the protection for the
(restore browse) information in the IDB only. The information is still
stored on media.
