If backups are only run Mon-Fri (5 days), and your dumpcycle is 7 days (1 week), then your runspercycle should be 5, not 10. Runspercycle is how many runs per dumpcycle, not tapecycle. > Now how do I configure amanda to do differential backups (level 1) on > Tuesday thru Friday?

You're trying to force amanda into your schedule (full Monday, incremental otherwise). The way amanda expects to be run is to be given the parameters above, and then be left alone to set her own schedule of full and incrementals within those parameters. IOW, she'll try to balance out the backups so that each night's are about the same size as the previoius nights while making sure she does (in your case) level 0 of each FS at least once a week. I haven't played around with bump settings, so I can't help there. I can just say that, unless there's a *really* compelling reason, it's best to let amanda set her own schedule. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
