I have the following configured to back up my laptop to my file server: root@galahad:~# cat /etc/cron.d/backup MAILTO=m...@vdwege.eu #00 04 * * * root /usr/sbin/btrbk --verbose --format=long run
Note: it is currently disabled. The only other places I have anything mentioning btrbk in /etc is in btrbk's config files: root@galahad:~# grep btrbk /etc/ -rl /etc/btrbk/btrbk.conf.example /etc/btrbk/btrbk.conf.old /etc/btrbk/btrbk.conf.local /etc/btrbk/btrbk.conf~ /etc/btrbk/btrbk.conf /etc/cron.d/backup And yet I find this in /var/log/btrbk.log: 2017-03-12T20:16:28+0100 startup v0.24.0 - - - - # btrbk command line client, version 0.24.0 There are no systemd timers related to btrbk either. This started about 1.5 months ago when I changed the backup time from midnight to 04:00; it took me some time to notice in the status mails that btrbk was creating duplicate snapshots, and checking the logs showed that at ran both at midnight and at 04:00. Disabling the 04:00 cronjob left the ghost cronjob at 00:00 intact. How do I find out why a periodic job is running with nothing obviously configured for it?
