Backupify, a cloud-based backup service offered for SaaS platforms including Salesforce and Google Apps, may expand to many other SaaS platforms through a developer kit designed for quick and easy integration. Backupify's proposition is that two clouds are better than one. Its service, available in the app stores for Salesforce and Google Apps, backs up enterprises' data from those SaaS (software as a service) platforms in Backupify's storage bucket on Amazon S3. Each enterprise's data there is encrypted with a customer-specific key.
