After months of successful backup using my 2 TB Time Capsule and the Time Machine program, I started getting the following message. The backup disk image "/volumes/data/My Name Computer.sparsebundle" Could not be accessed (error 111). I'm running OS X 10.7.5 and all my software is up to date. I know there's plenty of room on the disk as all the other devices backing up to this disk are working propertly. It shows over 1 TB of free space, so it can't be the disk is full.
