As Google looks to assure potential business customers that its cloud-based suite of applications is a worthy alternative to on-premises solutions, it's getting help from independent service providers.

One example is Backupify, an online backup, archiving and export service that unveiled support for Google Apps this week.

Cambridge, MA-based Backupify said it automatically backs up all data stored in a user's Gmail, Google Docs, Google Calendar, Google Contacts and Google Sites account. Google's (NASDAQ: GOOG) cloud-based system stores users files, but Backupify said its system ensures data won't be lost by error. Backupify actually leverages another cloud service, Amazon's storage cloud storage, to backup files.
