We have 90 (Win2000 + Win2003) servers running TSM client 5.3 to an AIX TSM 5.3.1.0 server. No problems with missed backups. Using the Scheduler, CAD, and Journaling in a timeframe of 7pm - Midnight. I did have to tune TSM when I went from 30 servers to 90 servers to prevent the missed backup issue. The parameters adjusted include: MAXSESSIONS, RANDOMIZE, MAXSCHEDSESSION. The backup window was also increased by 1 hour.
All running tsm client version 5 or later sending data to a tsm server on AIX running version 5.3 On a nightly basis I have at least 6 or 7 of these servers that miss their backups due to the service stopping. Is this common. Do other people experience these misses or is it something I need to look into on these servers. For the most part they are not the same server and I have the schedules spread from 7pm to 12 pm hourly. Just wanting to get a general guage of if there is something that I need to look into that I am doing wrong or if this is a normal and acceptable level of misses per night. Thanks, Andrew
