Re: BRMS suddenly requires second tape? - please read



fixed

Rob,

If your database is kept reasonably clean the reorg will not reclaim much in space, but it will impact BRMS performance. There is a price to pay for BRMS (it varies from system to system, but it will cost more time to do the backups) keeping track of everything, and the exit programs that get in between the tape and the save command. I think the overhead is well worth it particularly in a Domino shop like yours, but there is a price to pay.

I can see where that reorg can make a difference. Any drawback to doing
it daily?

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.
