Hmm, they do have Office 365 - that might be an option. It looks like it's not suitable as raw storage space (for, say, a full disk backup) without some gyrations: http://www.ytechie.com/2014/11/using-unlimited-onedrive-space-for-backups/

They could probably be served well enough by backing up just certain folder trees to the cloud. Folder syncing with OneDrive might work for that. However, that wouldn't provide any protection against CryptoWall etc. I'd prefer a solution that saved multiple versions of files or had some sort of file history function.
