Ha, yeah right. Marketers lie. This depends *heavily* on your data. > I ran amtape type and got the following. > > length 16534 mbytes > filemark 0 bytes > speed 2570 kbytes > > Does this look right? The first run didn't come close to 40gb or even 20gb. You had hardware compression enabled. tapetype puts out random data. The two don't like each other. Run tapetype again without hardware compression, and you'll get something close to 20. If you'll be using software compression, put that value in your amanda.conf. If you'll be using hardware compression, guess how compressible your data is, adjust the length accordingly, and continue doing so if you hit EOT too often. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
