VC-backed online data backup site Carbonite has closed the purchase of Zmanda, an open-source and cloud backup company for businesses. The Boston-based Carbonite, which started in 2005 as a data backup site for individuals and home users, has been expanding into the business arena. Zmanda's existing presence, along with its cloud-based architecture, will likely help Carbonite expand its business data storage offerings. Exiting investors in Zmanda include BlueRun Ventures, Canaan Partners, Gold Hill Capital, and Helion Venture Partners.
