On December 6th, 2007 IBM announced its acquisition of Arsenal Digital Solutions, a major player in the online backup service provider market. Arsenal provides online backup services to customers directly but other service providers (particularly telecommunication providers) rebrand and resell Arsenal's online backup services as their own. So the company is both provider and enabler. Arsenal is profitable, cash flow positive and has not required funding since 2002. It has approximately 3400 customers. IBM did not disclose the value of the acquisition.
It is important to note that the acquisition was made by IBM Global Services (IGS), not IBM Tivoli or IBM System and Technology. This acquisition is not about filling in a product gap (although IBM is lagging in data protection offerings that support deduplication), it's about ensuring a foothold in a critical market. In fact, the engine of Arsenal's service is EMC Avamar - what Arsenal provides is a software as a service (SaasS) wrapper around Avamar, everything you need for SaaS such as multi-tenancy, billing, reporting etc. IGS is clearly indifferent to the technology; they care about a dependable, scaleable online backup service
