crontab item doesn’t start #15

Hello, I always used this great script and restored my Rpi three times with it.

I never managed to get crontab working tough…

sudo bash /home/pi/RaspiBackup/RaspiBackup.sh start -i /dev/sdb -s 15000 -c /media/pi/Time\ Capsule/RaspiBackup/RaspiBackup$(date +%d-%m-%Y).img

this command works successfully when manually executed, but crontab never execs it (I even tried to run it each half an hour, nothing happens)

That's not an isssue of RaspiBackup.sh ...

  1. I would suggest to enter your backup command into root's crontab, so no sudo is needed.
  2. The command is executed by crontab with a minimal environment. it may be necessary to set additional environment variables or to specify paths explicitly.
  3. Is the crontab entry correct? Make yourself root sudo -i post the output of crontab -l

Without your cronjobs output (e.g. in /var/log/syslog) no further help is possible.

If you don't want to fiddle about crontab format, you should also have a look to anacron (which is installed in your Raspi by default). Write a small script which setup the env and starts the backup (the name of the script should have no extension). Put this script into one of anacrons folders (/etc/cron.hourly, /etc/cron.daily, /etc/cron.monthly).
