"Zmanda has scalability limits, Burgener said, "which is why they don't play in the large enterprise." There is a single master backup server associated with each backup catalog, "which means that realistically it can scale to support hundreds of systems, but not thousands," he said, while enterprise-class products like NetBackup, NetWorker or IBM's Tivoli Storage Manager "can manage multiple backup masters from a centralized management point all around a single backup catalog."

"Burgener said Zmanda's "standout technical feature is their scheduler, which is unique in the industry." Users give it a couple of parameters like how often they want a particular file backed up, and the scheduler determines how to perform the backup in a way that limits resource demands while adapting dynamically to changing environments. "Particularly for SMEs looking for ease of use, this is a huge advantage," he said.

"Zmanda's use of open protocols and formats is another advantage, Burgener said, limiting support and maintenance issues and making data restoration easier."
