Data domain backup appliance is a hardware device equipped with backup management software, storage servers, network interfaces and other backup management support software. It operates by connecting to local components. Previously installed backup software captures data from the linked and structured device and stores this data in the local storage environment. The same data can be reinstalled via the storage device when required. It can also provide data security and protection services by encoding data.

Data domain backup appliance has rendered backups faster and easier to manage.
