Network Backup
You can deploy the VSA on a virtual machine and the MediaAgent and deduplication node on a separate physical server. The VSA in the VM reads the data from the source VMDKs using HotAdd and transfers data over the network to the MediaAgents to be written to disk. Although source side deduplication and CBT reduce the amount of data transferred on the network, this method is the least preferred option and is recommended in exception conditions (for example, when there is not shared storage or backups need to be written directly to tape).
