****Any *SMers using NT Journal Backups**** **This question is posed to Tivoli Client Development [Andy Raibeck] or Tivoli Storage Solutions Software Development [Pete Tanenhaus] if possible!!!!** ---------------------------------------------------------------------------- -----------------------------------------------
I have read all of the information about Journal Backups in the "Tivoli Storage Manager for Windows Using the Backup-Archive Client" Manual and also the "4.2.1 READMe for NT" and it seems that there is more information needed on the behavior of Journal-Based Backups! I have an NT 4.0 client with TSM 4.2.1.15 (I will soon be upgrading to 4.1.2.20) client installed which it processes approximately 290,000 objects with about 2,200 (less than 1%) changing on a daily basis. If the amount of daily change activity is less than 5% is it still beneficial to use Journal Backups? When I first upgraded to 4.2.1.15 from 4.1.2.0, I decided not to perform a Journal backup on this particular client, so I DISABLED the service. On Tuesday, I started the Journal Service so it could begin its journaling process and log any changed objects or its attributes in the journal database. The backup still took 9.5 hours to complete with the same behavior as without Journaling. So, I continued to let it run the next night and it still took 9.5 hours as well. It seems as if the Journal Engine Service is not working properly! I still see sessions terminating due to the extensive processing/querying that the producer thread does while in an idlewait status.

Should I increase the IDLEWAIT time to 180 mins. (3 hrs) or will that only eliminate the multiple sessions timing out or increase the performance of my backup? Also, if anyone can explain this message it would be greatly appreciated? "psFsMonitorThread(tid 1044): Object 'C:\WINNT\Temp\TMP5.tmp' was deleted after notification."
