Hi Jörn,
it is not an app but a feature in ownCloud core. Have a look at
lib/backgroundjob/* and lib/public/backgroundjobs.php!
Background jobs has yet another feature I did not mention: queued
tasks. You can add a new task by using OCP\BackgroundJobs::addQueuedJob(
$app, $class, $method, $parameters ). $app is the app name, $class and
$method are used to call the function, $parameters is some text you
might pass to your task.
The main problem with this solution is that you don't know when it will
be executed. It's not necessarily happening immediately as you might
know it from delayed jobs in rails where a daemon runs in background all
the time. In the worst case (using AJAX, all users offline) it could be
executed weeks later :-/
Regards,
Jakob

Nice Work! Is it implemented as an app? Then the admin can deactivate
background jobs by disabling the app, anyway.
With regard to AJAX: what is our approach to various apps all
wanting
to make calls in the background. Possibly freezing the browser ui
when
using up all available connection (2 I think). Do we have some kind
of
queue for ajax calls? Should app authors always use the background
jobs?
So long
Jörn

I removed the option from the UI. In the program code the option
"none"
is still usable.

Ah sorry, I phrased it wrong. I didn’t mean »just use AJAX all
the
time and remove the option for cron jobs«, I meant »AJAX is
always
available and has no negative effect, so let’s just not have an
option
to deactivate background jobs«.
Of course if the server supports it, cron should be used.
TL;DR: Nice, let’s remove the option to deactivate background
jobs.
