Hello! I found that systemd no longer triggers the timer after waking the system. I'm not sure since which version this is true because I couldn't use suspend for a longer time due to driver bugs in the kernel.
# /etc/systemd/system/internal-backup.timer [Unit] Description=Daily Backup Timer [Timer] OnCalendar=03:00 WakeSystem=true [Install] WantedBy=timers.target The system will wake up and go back to sleep after 2 hours later as configured. But the associated service won't start: $ systemctl list-timers NEXT LEFT LAST PASSED UNIT ACTIVATES ... Mi 2016-08-31 03:00:00 CEST 19h left n/a n/a internal-backup.timer internal-backup.service ... 9 timers listed. Pass --all to see loaded but inactive timers, too. It simply skips triggering and queues the service for the next invocation.
