The Spanning 100% Restore Guarantee is based on the premise that if Google Apps data can be backed up, customers should be able to accurately and completely restore it. If not, Spanning will refund the customer 10 times the money paid for that user account for each failed restore operation.
The customer has the option to choose to receive this compensation as a refund or a service credit.
