Similar way it does tomorrow. Now what > is the difference between these two data? Amanda tends to run mostly level 0s and 1s. It'll "bump" backups to level 2 (or higher) if something gets too big and it needs to save space (and you can control the bump threshhold). As I said below, the goal is for each night's backups to be about the same size. A nice benefit of this scheme is that you generally will only need two tapes to do a full restore of a filesystem. > Now if suppose I want to backup a file, say "xyz" from the tape, where > will it search for the file? Will it search for today's or tomorrow's? Ah, here it gest nicer. You can specify the date from which you want file xyz. Want yesterday's version? Ask for it. Want last week's version as well? Ask for that too. How far back you can go depends, of course, on your dumpcycle and tapecycle, but that's the general idea. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
