Unitrends Free 8.1 Release Notes


Describes Unitrends Free features, enhancements, and fixes added in each release.


Unitrends Free is a virtual-only backup appliance that provides comprehensive data protection delivered through an intuitive user experience at no cost. We built this free version of Unitrends Enterprise Backup for the virtualization community by listening to the virtualization community.
