Catch-up with failed duplications
Can somebody help, please?
Our set-up: NetBackup 6.5.6 master/media servers, 150-odd clients/policies, D2D2T, images on fibre-connected SAN duplicate to a pair of tape libraries - one local, one remote. The DSSUs are swept every hour.
Scenario: Our fibre link to remote tape library is being respliced this weekend, so duplications to that library will fail during the hour this job takes. Duplications to local tape library should not be affected, so parent job will log as successful, and images will in time be cleared from the DSSUs.
Question: There won't be any backup activity to worry about, but what is the best way to catch up the missing duplications, to ensure we still have 2 copies? The main problem seems to be identifying what images were in the parent job's "plan" (only images completed or being processed when the fibre is cut will show in the Details, JobOverview tab). If I could list these "planned" images easily, I'd create a Bidfile and run bpduplicate. The only watertight way I can see, is to use bpduplicate with -s option (date/time) set far enough back to be sure to catch the oldest possible "planned" image - then all those images that already have the right number of copies will be skipped, and only the incomplete sets will be filled in.
But this looks a bit like overkill - is there a better way? I don't want to waste a lot of valuable "window" time by stopping all activity several hours before the work starts, and restarting everything afterwards - after all, no need to halt the other (local) tape library, which can keep going throughout.
