I'm having issues with my backup scripts. I wrote both backup scripts back when I was using FC1 on my client PC. One is a full backup of two user accounts in /home and then /etc and the other creates a list of files created/modified the date before the script is run and then only backs those files up. Full backup is on Sunday; every other day gets iBackup. They're listed in the crontab to run at 3am. The trouble is each morning when I'm reading my cron report for the backup it says that there was a problem with tar in my script, but when I run the script from the command line as root it works fine. I scheduled the script in root's (su -) crontab. Here is the /home/michael/system/iBackup script:
#!/bin/sh rm -r /home/amy/.Trash rm -r /home/amy/.thumbnails rm -r /home/michael/.Trash rm -r /home/michael/.thumbnails today=`date '+%m%d%y'` # Backup all echo Backing up both /home/amy and /home/michael # michael section filename=/backup/baby-gentoo-michael-$today.tar.bz2 find /home/michael -daystart -type f -mtime 1 > /home/michael/system/iBackup_list tar -c --file=$filename -j --files-from=/home/michael/system/iBackup_list echo Backup of /home/michael complete # amy section filename=/backup/baby-gentoo-amy-$today.tar.bz2 find /home/amy -daystart -type f -mtime 1 > /home/michael/system/iBackup_list tar -c --file=$filename -j --files-from=/home/michael/system/iBackup_list echo Backup of /home/amy complete filename=/backup/bullet-etc-$today.tar.bz2 find /etc -daystart -type f -mtime 1 > /home/iBackup_list tar -c -j --file=$filename --files-from=/home/iBackup_list echo Backup of /etc complete cp /var/lib/portage/world /backup And here is the contents of the cron report: rm: cannot remove `/home/amy/.Trash': No such file or directory rm: cannot remove `/home/michael/.Trash': No such file or directory Backing up both /home/amy and /home/michael tar: Too few arguments; will not create an empty archive.

Any ideas how I can make this work? -- gentoo-user@gentoo.org mailing list
