Zmanda, a company commercializing the open-source Amanda backup software, announced a partnership by which customers can store their data at Amazon.com’s S3–the online Simple Storage Service.

The partnership spotlights the growing influence of Amazon’s S3, which provides customers with online storage whose costs are tied to the amount of storage needed. It’s one of several online services Amazon offers.

Armed with Zmanda’s security and support Amazon S3 comes as a complete data backup and disaster recovery solution for all businesses.

“The combination of Zmanda’s affordable open source back-up software and Amazon’s online storage solution will fundamentally change the way businesses backup and archive corporate data,” said Chander Kant, Zmanda CEO. “With Zmanda and Amazon S3, virtually any business can afford the luxury of remote Internet storage that is immediately available, infinitely scalable, and secure.”
