Anacron is a dependency for cronie (the cron daemon) and is normally enabled. In your case, most likely it is just running the /etc/cron.daily or /etc/cron.weekly jobs you have defined, when you boot your system. The thing is, Anacron only runs if you boot after the scheduled job is supposed to run out of cron. It shouldn’t run twice. So maybe you have your backups scheduled in more than one place? Anyway, I agree with the others, use a lock file to prevent running simultaneous backup jobs. There are ways to do this with simple shell logic, with the “dotlockfile” executable. — Jonathan Billings _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
