Ok, here are the interesting pieces of the code:

interface backends : GLib.Object {
[...]
    public abstract async BACKUP_RETVAL start_backup(out int64
last_backup_time);
[...]
}

private backends backend;
var rv=this.backend.start_backup(out this.last_backup_time);


BTW, Jim Nelson answered that I have to do something like this:

run_async.begin(on_run_async_completed);

/* ... */

void on_run_async(AsyncResult result, Object? source) {
    int result = run_async.end(result);
}


Is this correct?

Thanks.
