when I wanted to backup as usually I did. An error appeared "The backup disk image “/Volumes/Data-1/chan’s MacBook Air.sparsebundle” is already in use."
Please advise how to fix it.
See the more like this on the right hand side.. there are at least 4 or 5 current discussions on this page about this problem.
Reboot the TC or reboot the Network.. it is Apple's woeful networking in Lion and ML that is behind it.
