You have hit a known bug, which has just been fixed, so it should be in 
the next releases of 4.13 and 4.14.

You can use the online backup from cron, just create a script (If you 
cannot, talk nicely and I will give you a copy of mine) , basically it 
boils down to using kerberos and adding '-N' to the command.
