Distributed ROBO backup to disk is available from the following vendors: Asigra Inc., EMC Corp./Avamar Technologies, EVault Inc., Iron Mountain Inc., Signiant Inc. and Symantec Corp. (see "Distributed ROBO backup-to-disk product comparison"). Distributed ROBO backup to disk is an excellent choice when data protection is the primary issue or there are numerous mobile users. It's not a good choice when the primary ROBO issue is performance when working with centralized data center applications.
Centralizing ROBO applications and their data at the primary data center has enormous economies of scale. To do so effectively also requires implementing technologies that eliminate TCP WAN transmission issues. When an organization contemplates how it will centralize distributed ROBO data, it must first determine which applications will be centralized and the application's required performance. It's possible, and in many cases highly likely, that multiple technologies should be deployed to meet the organizations needs.
