Most start out with perhaps 10 to 20 dle's, then add 20 or so for run two, wash rinse and repeat till you have them all. Then give amanda a couple weeks to work out a schedule that loads each (v)tape with a similar amount of data. It will shuffle the order of the levels, but will also prevent any backup from going above the dumpdays for the new level0 as set in your amanda.conf.

They can and will have a huge effect on how much tape is used per run. This is what I have, but isn't yet ideal to me: bumpsize 2 MB # minimum savings (threshold) to bump level 1 -> 2 bumpdays 2 # minimum days at each level bumppercent 0 # new var I didn't know about till Dec 2015 bumpmult 1.125 # threshold = bumpsize * bumpmult^(level-1) Everything but bumpmult s/b integer. > Kind regards, > > Chris > > > 0 19098649k waiting for dumping > > 0 9214891k waiting for dumping > > 0 718824k waiting for dumping > > 0 365207k waiting for dumping > > 0 2083027k waiting for dumping > > 0 3886869k waiting for dumping > > 0 84910k waiting for dumping > > 0 22489k dump done (7:23:34), waiting for writing to tape > > 0 304k dump done (7:22:30), waiting for writing to tape > > 0 2613k waiting for dumping > > 0 30k dump done (7:23:07), waiting for writing to tape > > 0 39642k dump done (7:23:07), waiting for writing to tape > > 0 8513409k waiting for dumping > > 0 39519558k waiting for dumping > > 0 47954k waiting for dumping > > 0 149877984k dumping 145307840k ( 96.95%) (7:22:15) > > 0 742804k waiting for dumping > > p" 0 88758k waiting for dumping > > 0 12463k dump done (7:24:19), waiting for writing to tape > > 0 5544352k waiting for dumping > > 0 191676480k waiting for dumping > > 0 3799277k waiting for dumping > > 0 3177171k waiting for dumping > > 0 11058544k waiting for dumping > > 0 230026440k dump done (7:22:13), waiting for writing to tape > > 0 8k dump done (7:24:24), waiting for writing to tape > > 0 184k dump done (7:24:19), waiting for writing to tape > > 0 1292009k waiting for dumping > > 0 2870k dump done (7:23:23), waiting for writing to tape > > 0 13893263k waiting for dumping > > 0 6025026k waiting for dumping > > 0 6k dump done (7:22:15), waiting for writing to tape > > 0 42k dump done (7:24:24), waiting for writing to tape > > 0 53k dump done (7:24:19), waiting for writing to tape > > 0 74462169k waiting for dumping > > 0 205032k waiting for dumping > > 0 32914k waiting for dumping > > 0 19999k dump done (7:24:02), waiting for writing to tape > > 0 854272k waiting for dumping Copyright 2018 by Maurice E.
