The cronfile in question sets a very unusual schedule. According to that backups should happen at every round hour, but only on Fridays. The only solution to this that I can suggest is adding and additional "custom cronline" option to the interface, so that it does not get confused at those. Did you write that cronline yourself, or did the interface give you such a line? In the latter case that is the main bug here.
