Time Machine not backing up
I'm getting this message each time Time Machine tries to backup to my Time Capsule:
Time Machine couldn't complete the backup to "Time Capsule"
The backup disk image "/Volumes/myname's/Time Capsu/myname's Computer.sparsebundle" is already in use
It was backing up perfectly earlier this week, and nothing has changed on my system. I don't undertand this message, can anyone help me out please?
iMac, Mac OS X (10.5.2)
