Backups of log copy pools

If you take backups of both the log and database copy pool, you can use the backups to restore the log copy pool.

When you use backups to restore the log copy pool, if the active log data sets are stripped, or if the log copy pool is for a data sharing environment, you must specify the data complete LRSN during the conditional restart in the following scenarios:

• You are cloning a Db2 system by using a system-level backup as the source. In this case, conditionally restart Db2 with an ENDRBA or ENDLRSN that is equal to the data complete LRSN of the system-level backup.
• You are performing a system-level point-in-time recovery. In this case, conditionally restart Db2 with the log truncation point equal to or less than the data complete LRSN of the system-level backup. Use the data complete LRSN as the CRESTART ENDRBA, ENDLRSN, or SYSPITR log truncation point.

You can determine the data complete LRSN from the following places:

• Message DSNU1614I, which is generated when BACKUP SYSTEM completes successfully
• The report that is generated by the print log map utility (DSNJU004)
