Can a backup be stopped if not completed by a certain time?
I run a pre and post command to stop and then restart applications on an NT server in order to back it up. The applications have to be brought up by a certain time in the morning. Is there any way I can do a time check during the backups or set a time for the applications be restarted even if the backup has not completed?

You can look into two server options that can cancel a session if is isn't getting X amount of data transfered after Y period of time. THROUGHPUTDATA- THRESHOLD Specifies a throughput threshold that a client session must reach to prevent being cancelled after the time threshold is reached. THROUGHPUTTIME- THRESHOLD Specifies the time threshold for a session after which it may be cancelled for low throughput. Say you have a 120 GB data base, and you expect 40 GB/hr transfer rate thus it should finish in 3 hours... throughputtimethreshold 180(minutes) throughputdatathreshold 11650 (KB/sec) So if my math is right, the above would cancel ANY client session after 3 hours IF it wasn't running at 40 GB/hr. NOTE the ANY client session... I don't know if there is anything on the client side to do the same sort of thing. Dwight E.

Hmm. I'll have to look into those throughput params Dwight mentioned. Anyway, if that won't solve the problem, you can most likely script a forked backup and a sleep, with a test for the backup process to kill if necessary at a certain time. Or you can have 2 schedules, one that starts a backup in the background and immediately exists, and another schedule (or AT command) at a later time that runs a script to test for the dsmc process and kills it if necessary and starts your apps. Or, you can have an admin script on your TSM server that, at a certain time, checks for any sessions belonging to the client and cancels them (should be possible, but I don't use those admin scripts - I just use scheduled/cron'd shell scripts, which is also very do-able). I'm assuming you want to kill the backup, then start the apps, but these suggestions, except the canceling sessions, could be implemented without killing the backup. I hope this helps.
