It would really help if you would tell us what os and system that you are using. But it looks like you are using SunOS. On SunOS, /dev/fd/x is a psuedo filesystem. Use "man -s4 fd" for info. The floppy driver is called fd, but the devices are called stuff like "/dev/diskette".
You will never succeed in backing up /dev/fd on a sun. You're just causing tar to effectively dup its own file descriptors.

"not enough memory"
I have done a new test backup and restore using the same commands and they work.
ANY IDEAS ? (2 Replies)
