OK, all looks good there, and it's not the "simple" explanation. So
that means we'll need a good log from your backends run at -v
file,schedule --loglevel debug . Whole log please (shut down the
backends, then start at that level and run it until you've seen a
recording fail when it chooses the wrong directory).
Thanks,
Mike
