I have a 15" mac book pro with a time capsule for back up.
yesterday i checked my back up to find that the last back up was dated 23.12 2011.
by coincidence just a week before this i installed a wireless remote camera working off port 80.
since this time the time machine wheel on my screen as been spinning as if backing up but apparently not backing up.
when i try to back up by using the 'back up now' it appears to be working but has been doing that for over 24 hrs with still no back up.
i am wondering if i have disturbed some setting whilst installing the camera ??.
would appreciate any advice.
