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: # /usr/openv/netbackup/bin/admincmd/bppllist TEST-std-freq -L Policy Name: TEST-std-freq Policy Type: Standard (0) Residence: TEST-dsu Client/HW/OS/Pri: mouse Solaris Solaris9 2068001349 0 0 0 ?

"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. :-) _______________________________________________ Veritas-bu maillist - Veritas-bu AT mailman.eng.auburn DOT edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
