Re: BRMS suddenly requires second tape? - please read

(V7 information)

There are two parts of BRMS Maintenance that need to be run, and I do it every day on my client machines:

Remove Media Information should be set to remove expired media data including media content.
Run Cleanup Operations should also be *YES

I also allow BRMS to change journal receivers, and reorganize the database. These two options can be done less frequently but they should be at least monthly.

It's the remove media information and the clean up that really saves space in the QUSRBRM objects.

In my view, best practice has the BRMS Maintenance procedure run a short time after all the save activity is done for the day. It can run in the middle of the day if desired, no real system impact should detectable, except maybe the first time it's run.

Right now, I can't remember what it was

Although the physical tapes actually expire
....the data containing that info in QUSRBRM does not get cleared out

Try this, I bet it helps

Interesting thought Terry but I can't think of any process in BRMS
maintenance that might cause an extra tape mount. If one file on the tape
is still current (not expired) then BRMS will not expire the tape volume
either.

Still, running BRMS maintenance every day is still a best practice.
