Time capsule disk error
I have a first generation Airport Time Capsule, a year ago I bought a mac mini and am using my old TC with it. I get the following error when trying to backup "The backup disk needs 70.87 GB for the backup but only 30.91 GB are available. Select a larger backup disk or make the backup smaller by excluding files"
When I check my TC it looks like there is only one backup saved. I don't know how to check the size of my TC disk, but I think it is smaller then the 600gb on my mini that I am trying to backup. Not sure. Any suggestions will be appreciated.
