Having the same issue on one of my sites, the one site running on a IIS machine.
Running the most current version of both WordPress and BackWPUp (as of this writing anyway, 03.20.2013).
Any resolutions to this found?
Same problem on Linux server.
See previous post http://wordpress.org/support/topic/305error-db-backup-wont-complete
The weekly dBase backup has still been running! I can’t abort it.
Deleted plugin and reinstalled and still get this!!!! So even with no jobs it thinks one is still running
