Ok, first: Why it doesn't work I simply don't know. You should test if this is a problem with find, or the egrep command, cpio or cat by making verbose output into a own log file.
But maybe you should not use this (in my opinion) unusual command "find / -print ...". Instead use tar, like: tar -zcvf /media/mirror/`date +%F`.tar.gz -C / --exclude=/media/* --exclude=/proc/* --exclude=/sys/* --exclude=/mnt/* (please test this first before going productive) or use rsync. You will find a lot of examples in our great? world. Best regards, Benjamin Schmidt Haines Brown wrote: > I asked this question some time ago.
