Tony,
Is more tape being used. Have you ever had to use a second tape to complete
the backup. If so it could be the tape drive head is wearing out. Have the
tape mechanism replaced.
Regards,
Bill Green

> 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.
