Limit exceeded and backup was not completed Removed the key from your post, because it's not safe to post such information here.
Regarding your problem:
1TB limit means that you can at any time have at most 1TB of data on the cloud account managed by CloudBerry Backup. E.g. you can upload 800 GB, then another 200GB, then delete 300GB but you can't exceed the limit of 1TB. The limit is imposed on Aug, 15 2014 and it doesn't affect any purchases made before.
To be able to back up more than 1TB you need CloudBerry Backup Ultimate Edition.
You can upgrade by paying the difference:

If you're sure that your current data set doesn't exceed this limit you'd need to contact our support department.
