Hello Everyone
My Production Server is a 979KS100 6.5 OS (ECOMETRY APP) we do a full nightly backup of 30 gb's on a DLT4000 Tape drive. We set our JOB LIMITS TO 17 and we run 14 - 16 system jobs 24x7. Our backup starts nightly at 2:00 AM and the compeletion time was 4:00 - 4:15 AM = 2 1/4 HOURS of run time. A month or so ago our backup started to run longer, at time taking 5, 6,7 hours to complete (6:00,7:00 AM), same 30 gb's.Before the backup starts, in the JOB stream we do a SJ (SHOW JOBS) to list the jobs running.Last weeek feb 03 - feb 06, the backup ran more than 5 hours, yet Friday's feb 07 it ran 3.75, saturday's ran 2 hours 15 min and sundays ran 1 hour 55 mins.
Again Monday 10th, tusday 11th ran over 5 hours. Using Lund Performance SOS/3000 System advisory, I check the log from start to finish.No job is hogging the cpu time
The one example below will show how proccess and job are running during the backup, at times some jobs might take 13.0% of cpu, but! no major concern.

Can anyone offer any input to solving this issue of mine. "WHY ARE MY BACKUPS RUNNING LONGER?" All inputs will be appreciated
Thank You.
