A quick short course: dumpcycle -- max time between level 0s of any one DLE (disklist entry) runspercycle -- number of times you'll run 'amdump' in one dumpcycle tapecycle -- how many tapes you will let amanda use and, for changers runtapes -- max number of tapes amanda can use during one 'amdump' The key here is "what is a DLE". If you're using dump as your backup program, a DLE must be a filesystem. If you're using tar, it can be a filesystem or just a directory within a filesystem. So, yes, amanda can handle this. Just split your filesystem(s) into multiple DLEs, each smaller than your tapesize. And then set the other parameters such that you can fit everything in the available number of amdump runs/tapes. Good luck. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
