A remote backup appliance is a hardware device that ships with a backup software application pre-loaded. The appliance is used to back up corporate data that is located outside the corporate data center.
When selecting an appliance for remote backup, data storage administrators need to consider encryption features, fast network connectivity and simplified management features. Data deduplication, which is offered in most remote backup appliances, is a key feature because it reduces the amount of data that is sent over the network.
Remote backup appliances play an important role in any company's disaster recovery (DR) plan.
