"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."
