That depends on your dumpcycle. Amanda's goal is to backup about the same amount of data every night -- not to fill the available tape(s). > I assume that if an amdump fits on one tape, a weekly cycle would use only > the 7 tapes and be happy.

Does amanda track > it all well enough? Yes. Yes (well, a couple of 2TB partitions, a .5TB, and a 1TB with 100GB tapes). Works well, tracking isn't *too* bad as long as you remember to comment out DLEs you get rid of rather than deleting them. Not quite -- you need to do some stuff by hand. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
