Re: Varying back up times

We do log the save, however we log the library name, job name/user/number
of the backup, timestamp of when the save of that library completed. To
figure out the duration of the save we would have to subtract the previous
libraries timestamp. Sort of like a look behind function. And for this
purpose, if I can't do a simple sql function I really don't want to write
a program to do so.

So what would I do based on this information? If the time on library X
was more than the previous night but library Y wasn't I would do...?

We use PRTERRLOG daily.

Can you match up from the joblog where abouts the backup is at in your
time
interval chart by day, like does it spend more time in a specific library
than others.

Do you ever use PRTERRLOG on your tape volumes.

We have a backup process that runs anywhere from 6.2 to 8 hours. Which

out in the joblog. Most runs it's a 1,000 page joblog. Time shots at
various pages:

FastDay SlowDay
P1 19:30 19:30
P100 21:02 21:03
P200 21:23 21:32

P800 0:32 2:08
P900 1:25 3:05
P1000 1:48 3:27

CPU Utilization never hit 10% on fast night. On the slow night it
averaged between 10 & 20% with only 1 spike that hit 42% and only two
spikes that hit 30%
