No thank you. :) I tried dump first since it was there, and it was the easiest to figure out how to operate correctly when I first put 386bsd on the system. The problems were that it wouldn't compress, and each time a new disk was requested, it would fork off a new process. Eventually, after many disks were written, my loadavg would skyrocket (a symptom that I've run out of RAM) and I'd be forced to reboot. Right now I use a program called 'backflops' (came from a Linux system, easy to convert to 386bsd btw) that makes for a painless interface to 'tar' to write multiple compressed floppies. However, I've done some experimentation since I saw the articles about 'tar' not working with /dev/* here and on another Unix conference (RIME). So far, I am not convinced that this is a problem. Executing 'tar -cvf dev.tar /dev/*' produced a tar archive all right, and it looked quite reasonable when I did a 'tar -tvf' on it. Whether it will restore it is something else, and I haven't tried that yet. But I don't see any reason why it wouldn't. The statement 'Why not? Because it's a special file' or some such doesn't wash. >Heiko W.Rupp Gerwigstr.5 7500 Kh'e 1 hwr@pilhuhn.ka.sub.org +49 721 693642 >The Abrams' Principle: > The shortest distance between two points is off the wall. -- ------------------------------------------------------------------------ in real life: david fox email: dfox@quack.sac.ca.us 5479 Castle Manor Drive, San Jose, CA 95129 "Thanks for letting me change some USA magnetic patterns on your HD" -me 408-253-7992 "You've just won an absolutely FREE trip to the Isles of Langerhans" -me ------------------------------------------------------------------------
