Rainer I don't know the answer to your 1st question - we just accept the thousands of messages on the log. We run the log through a filter script to select the ones we're interested in, so we keep the full log on the server in case we need to read it, and use the filtered version for daily monitoring.
The standard answer to your 2nd question is to put the backup command into the background (possibly by using a script), so that the scheduler returns control immediately and can then go on and do other things like archiving logs. We've had to do this for all large backups (SAP, Domino and filesystems), otherwise disk areas for archive logs fill up, as you predict. You lose the return code in TSM, but if you write a script you can monitor that yourself. See the ADSM-L archives for many discussions of this. Richard Foster
