When uploading a backup, it fails with the error Storage Quota Exceeded.
Internally, this error is logged as ZIB_CLOUD_QUOTA_EXCEEDED
What's going on?
When a backup is being prepared for upload, ZCB checks to see if there is enough space on the cloud to store the backup.
If there is not enough space, the upload will fail with Storage Quota Exceeded.
For example, if your backup is 80GB, and you have less than 80GB of free space on the cloud, the upload will fail.
Purchase more storage
More storage can be purchased by clicking on the Cloud menu, followed by Buy More Storage.
Delete backups to free up some space
Backups can be deleted in many ways. Please see How to delete backup data from disk or cloud.
