Problem description: | |
A backup to TSM shows incorrect size estimate. By default an online backup will include logs. The backup image and the logs are sent in two separate files to TSM. When the size estimate of the database is calculated it is incorrectly applied to the logs file as well. the result is a size estimation sent to TSM almost twice as big as the correct size. Example below: ==> db2adutl query db Test|more Query for database Test Retrieving FULL DATABASE BACKUP information. 1 Time: 20100223010001 Oldest log: S0000098.LOG DB Partition Number: 0 Sessions: 2 ==> dsmc query backup /Test/ API 90,858,508 KB 02/23/10 01:00:03 DB2DATA A /Test/NODE0000/FULL_BACKUP.20100223010001.1 ==> data API 90,858,508 KB 02/23/10 03:28:54 DB2DATA A /Test/NODE0000/FULL_BACKUP.20100223010001.2 ==> log file(s) User data is ~90 GB and log file is 4MB. And yet both backup images are ~90GB in size. | |
