Online Business Backup

Are there any online backup that you insurance against losing all your data if they go out of business?
I found many hosting companies, such as X-Drive, which offer a backup of files online. what I want is a guarantee by, say, a large insurance company, which provides that if a company goes bankrupt or goes bankrupt, the files will be lost. what should be offered, but it seems that no storage sites of important files or just by offering such a guarantee, or not mentioned in the FAQ or promotional material. Thank you!
