Using backup avoidance

The Recovery Management for Db2 solution exploits backup avoidance technology to reduce backup time.

This technology analyzes the log ranges to identify and exclude from the backup JCL any objects that have not changed between the last backup and the current time. This feature is particularly useful for systems with large numbers of objects that change infrequently (such as SAP).

You activate the backup avoidance feature by specifying the XUNCHANGED option of the ARMBGEN batch program.

For more information about the XUNCHANGED option, see the ARMBGEN section of the BMC AMI Recovery Manager for Db2 documentation
