[systemd-devel] wake from sleep on systemd timer

[Kai Krakow]

Hey list,

Are there any plans to enable waking the system from sleep upon some timer 
events defined in systemd units? By no means it should wake up on every 
timer. But it should be able to wake the system for specially labelled timer 
units and after finishing them put the system back to sleep (except some 
user activity has been detected).

My curiosity comes from the idea to have, for example, a backup job running 
each night.

As an alternative I'd like systemd to catch up missed timers upon boot if 
they are labelled with some sort of importance and have not been run since 
the last successful schedule. Is that already possible? I know anachron has 
such capabilities, but since systemd has cron-like capabilities I'd rather 
like to completely move away from any sort of cron.

As a rough idea, maybe that could be implemented by some sort of

Type=dontmiss
Type=catchup

or similar...

Thanks,
Kai
