Sorry, I had the INTERVAL and FREQ parts backwards and it was not very
clear. The write-up below may make more sense:
Freq is measured when the backup ends if you are using Freq based
scheduling. If you are using Interval mode scheduling when the backup ends
does not matter. Its a bit confusing but as everyone knows there are only 2
types of schedules, calendar and freq. But if you chose freq based schedule=
s
then bpsched has 2 processing modes it can use and that is freq and
interval. Here are a few snips from a verbose bpsched that shows this.
06:03:03 [2116.2240] <4> in_interval_mode: IN INTERVAL MODE
.....
15:31:26 [1820.1800] <4> in_interval_mode: NOT INTERVAL MODE -- not an
integral number of days
15:31:26 [1820.1800] <4> backup_due: using frequency-only mode
Hope that helps
Steve
