My 2TB backup drive is full. I have about 750GB of data that is backed up. In the old days I could pick what type of backup to do. I could append for a week or month and do a full backup at the end of the month to create sets. I would delete old sets and recover the space. Now I have one huge backup and no way to delete data from it. Do I need to start over or just keep buying more space, a considerable waste of money? My current drive is external. If I get another drive will it span the volumes or will the program see it as another backup device and create another set? This is not user friendly. My 250GB laptop takes 2 days to backup, just silly.
