Yesterday I've configured rsnapshot on a debian 9 machine, but the cron's I've set for the backups in /etc/cron.d/rsnapshot are not being executed.

Also, after I save & close the /etc/cron.d/rsnapshot it doesn't say it installed the new crontab.

How can I find out why it's not being executed? I've already done some searching on this website and have found the following things:

  • There are no entries in /var/mail
  • Right permissions + owner for /etc/crontab

Also the cron process is running:

ps aux | grep cron root       364  0.0  0.0  29664  2880 ?        Ss   Oct12   0:05 /usr/sbin/cron -f

The cron is set as following:

0 */4* * *      root    /usr/bin/rsnapshot hourly

Any suggestions on how I can find out why the crons are not being executed? I've already tried executing the command manually (this works) and have also tried nano and vim while editing and closing the rsnapshot cron file.

You miss one space in the cron record. I should be like this:

0 */4 * * *      root    /usr/bin/rsnapshot hourly
  • Sorry for that, I've corrected it. However it still doesn't say it saved the new crontab once I close the file. Nov 6, 2018 at 8:22
  • @user2191227, you will get this text if you exec crontab -e and not when you use cron.d directory Nov 6, 2018 at 8:26
  • Ah alright thanks for clearing that up, I'll wait and see if it worked out Nov 6, 2018 at 8:36
