I'm using a 22-tape ADIC changer with the current configuration (and I know it doesn't do either A or C above) that works just fine. Now, I am thinking about going to this Daily config: -- dumpcycle 1 week runspercycle 5 runtapes 2 tapecycle 44 Looks good. And adding another configuration that runs once a month and does a full: dumpcycle 0 runspercycle 1 runtapes 22 tapecycle 22 Set tapecycle to be very large. That way amanda will always want new tapes. Otherwise she's going to think you want to keep using the same 22 tapes. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University

It means that is the *most* tapes it will use, but if just one tape is sufficient for a given run, that's all that will be used. If your device has cartridges that hold 22 tapes, that can cause things to get shifted so you don't swap the cartridges at nice points. John R.

That's the answer you gave me about 3 weeks ago when I asked what does this runtapes thing mean? :). If your device has cartridges that hold 22 tapes, that can cause things to get shifted so you don't swap the cartridges at nice points. I've thought about it. It won't be as automatic as we want, but a) we'll probably be backing up 2 tapes worth soon anyways b) the sysadmin will just have to move tapes with a little more intelligence :. Another option is that the ADIC doesn't have a tray or anything. The tapes go into their own little slots. Thus, we can just swap out the ones we know we've already used from cartridge 1 and put in cartridge 2 tapes in their place. So long as amanda is convinced that it is a gravity stacker and doesn't go backwards (your advice, again). Thus, he can take out the first 10 tapes when amanda gets to tape 11 and put in 23-32 there. Then, when it starts sucking from the 23 bank, put in 32-44. Thanks for the advice, Mark -- http://www.mchang.org/ http://decss.zoy.org/

They're right when they say the first thing that goes with age is, ummm, hmmm, now what was it they say goes first ... :-). Another option is that the ADIC doesn't have a tray or anything. ... That sounds like a plan. Mark John R. Jackson, Technical Software Specialist, [EMAIL PROTECTED]
