Backup services can save hardware and staffing costs, but beware of surprise fees. ORGANIZATIONS GO TO great lengths to ensure there are no surprises in their operational environments. Even so, several well-publicized events involving backup storage as a service (SaaS) have exposed costly vulnerabilities in a number of shops. Given that SaaS is new to many firms, it's understandable that some possible scenarios simply weren't considered in the review process.

Since then, the technology has been incorporated into data protection products and its role is now likely to expand. In addition, rapid data growth and shrinking backup windows are two of the trends that support the increased adoption of CDP.
Economy and capacity at odds
With fewer bucks in the budget, storage managers are facing some constraints in dealing with growing storage capacities.
