I have a Macbook about 4 years old. 250gb memory which is so full I cannot update to Mountain Lion so am using snow Leopard 10.6.8 I bought a Time Capsule 2tb and tried to back up before deleting to make space. After 36 hours I am nowhere. after starting the full back up the programme stopped several times with the message "The backup was not performed because an error occurred while copying files to the backup disc". I went to disc utility and actioned "Repair disc Permissions" several times. I also actioned "verify Disk". When I try to reenter the Time Capsule to see what I have it states in progress. So cannot see anything. Has anyone any idea of what I am not doing or what the problem is? The packaging states that you just plug and go. Not so. any help?
