Time Machine does not do initial back up and created partial backup file
Hello. I got a new TimeCapsule. When I did the initial backup, it only backed up a small part of my computer. And it didn't time stamp "Last Time Capsule Backup". When I "Enter Time Machine" I see Monday Jan 22 in a time scroll but there is nothing on the drive ( I deleted partial backup file). I did not even have this TimeCapsule in January, I just bought it yesterday. Thanks in advance for help!
