I win. When multiple schedules are due; the schedule with the longer frequency
interval runs; retention has nothing to do with it.
Details on request, but here's the edited summary of the class and bpdbjobs:

"full" has a frequency of two hours and a retention of one day.
"diff" has a frequency of one hour and a retention of one week.
# /usr/openv/netbackup/bin/admincmd/bpdbjobs|head -20
Time Type State Status Policy Schedule
01:00 Backup Done 0 TEST-std-freq diff-f1h-r1w
00:00 Backup Done 0 TEST-std-freq full-f2h-r1d
23:00 Backup Done 0 TEST-std-freq diff-f1h-r1w
22:00 Backup Done 0 TEST-std-freq full-f2h-r1d
21:00 Backup Done 0 TEST-std-freq diff-f1h-r1w
20:00 Backup Done 0 TEST-std-freq full-f2h-r1d
Summary: despite its shorter retention, the schedule with the longer frequency
interval always wins out.
Hmmmm. Macallen is a little pricey; Glenlivet will do nicely. :-)
