It means that when tar followed all the instructions you gave it, there was nothing left to put in the archive, so it sanely refuses to create the archive.

Re: backup script partly fails when in cron.weekly
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.

backup script partly fails when in cron.weekly
I asked this question some time ago. I've a script in /etc/cron.weekly named "backup" (rwxr-xr-x root/root) that looks like this: #!/bin/sh mount /media/mirror dirName=`date +%F` mkdir /media/mirror/"$dirName" find / -print | egrep -v "^/media|^/proc|^/sys|^/mnt" | cpio -pdmuv \ /media/mirror/"$dirName" 2>&1 | cat -vt umount /media/mirror exit 0 I regularly get only partial backups when run by cron, but full backups if run from command line by root. For example, in / I have two symlinks. Both are rwxrwxrwx root/root, but only one gets backed up. Another example, /home gets backed up, but /etc does not, even though both are rwxr-xr-x root/root, Yet another example: In / I have two plain text files, both are rw-r--r-- root/root, but only one gets backed up. Plenty of room on the backup device (external UPS drive). My syslog reports the backup started. No other log entries of interest: Dec 9 04:00:01 teufel /USR/SBIN/CRON[23041]: (brownh) CMD (/home/brownh/scripts/backup) Dec 9 04:00:01 teufel /USR/SBIN/CRON[23043]: (brownh) CMD (fetchmail) Dec 9 04:00:01 teufel kernel: kjournald starting.
