One of my machines has 950 clients, all under some local administration. A graduate division lost their budget folder two weeks ago and are still working on recovering it because it's spread over 50-75 tapes. But we're still working on the politics of collocation for these users. My other machine has 850 clients, mostly under central control, so I collocate everything but desktops. Critical restores go much quicker, but I have to spend at least 8 hours a week husbanding a too small scratchpool. >2) Secondly, can someone tell me a good, clean, simple way of achieving >only collocating certain clients. I use multiple domains with diskpools that go to tapepools that do or do not collocate. >3) Also, baring in mind that at present, we back up all clients to one >COPYPOOL, what would be the implications of a) moving some clients to a new >backup COPYPOOL (what happens to all the data currently stored on the >original COPYPOOL and b) turning off collocation for the original COPYPOOL >(i.e. would this lead to a very long reclamation run). Everything goes to a single copypool. If I have to restore a volume, TSM is bright enough to figure things out. >There is probably a lot more inf. that I should have included here, but I >am relatively new and probably don't know the questions to ask. > >Thanks again and I look forward to any help you can all give me. > >All the best > >Farren Minns
