Barry I just got my interest piqued a little by your question. So, here is what got my interest -- why would you take full volume dumps if they haven't changed in months/years?

I run a set of jobs weekly to dump just my system packs to tape using DFDSS. Several of the packs, such as the DLIB volumes, haven't changed in months/years (2.10 is out of support). Most weeks, the EXCP count is very close to last week's count for each volume. Once in a while, the count will jump up for a one week (or occasionally a few weeks) and then return to normal. When it happens, it seems to happen for all the jobs. Some of the packs are pretty full and the delta is less than 10%. But my SMPPTS dataset is alone on a pack and has been almost empty since my last accept run. Its normal EXCP count is 700 and an increase of 400 is a significant percentage. The times for the jobs do not show a corresponding delta. It doesn't seem to make any practical difference but it has piqued my curiosity. No virus found in this outgoing message.
