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 Modify the backup specifications by changing the logging level and

IDB Growth	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.
