the following line doesnt work as a cronjob;
tar -C /var/www/dokuwiki -c -v -j -f /storage/dokuwiki/dokuwiki-backup-`/bin/date +%Y%m%d`.tar.bz2 conf data lib
The tar will be created but not all files/folders are in it.
what am i doing wrong?:
this is in my crontab -e;
# m h dom mon dow command
55 11 * * * /bin/bash /storage/dokuwiki/scripts/backup
