I honestly haven't changed anything. The only thing that happened was that I had to run amflush on July 31, because for some reason the amanda-related services on the backup server seemed to have hung (but that's an entirely different issue). That si just a wilkd guess, but how about the

Frederic, What are the tuning parameters ? Are you bumping into an amanda imposed bandwidth limit ? What are the settings for max dumpers and number of jobs you can run at one time for each client ? What level of SW compression are you using ? On Fri, Jul 09, 2004 at 10:22:46AM -0400, Joshua

More holding space is going to give you the biggest boost. And be sure to have fast holding disks. LTO drives eat data at 20-30MB/s if your disk can send it that fast; in my setup (currently 400GB/night, and struggling to finish in 24h!), I've only two IDE holding disks, and the combined

The Bandwith I put in the amanda config is 5000 kbitsec ... The bandwidth number in Amanda has very little to do with how fast it will actually transfer data (which is confusing, to put it mildly :-). When Amanda estimates how large each dump is, it also looks at how fast they ran in the past
