Figure 2 illustrates the dynamic NAS asset backup and recovery solution with Data Manager.
The NAS array is the primary storage location for the NAS data from where the data is read and sent to the secondary storage location, which is PowerProtect DD series appliances. Data Manager uses specialized NAS Protection Engines to protect the NAS assets.
The NAS Protection Engine is used as a data mover for backup and recovery. Containerized NAS agents run on the NAS Protection Engine to support multiple NAS protection operations. Each NAS container is preinstalled with NAS agent and FSA agent. NAS Agent will use FSA binaries for backup and recovery and orchestrate them to run backup and recovery with multiple threads or streams to achieve optimal scale and performance. Once the backup is completed, the Search Cluster creates indexes for the NAS backup and supports search and FLR.
