NAS Data Manager (NASDM): The NASDM microservice in Data Manager is the pillar for NAS workload backup and recovery.
NAS discovery plug-in: The discovery plug-in enables automated discovery of supported Dell Technologies NAS appliances as assets and stores the asset information to the Elasticsearch database.
Virtual Proxy Orchestrator Daemon (vpod): NASDM uses vpod to orchestrate NAS assets protection using NAS Protection Engines. NASDM integrates with vpod component for backup and recovery.
The Protection Engine is an external virtual machine running on a VMware vCenter for Dynamic NAS Protection backup and recovery. Each Protection Engine can run multiple containers and each container is preinstalled with NAS agent and FSA agent. A Protection Engine can receive multiple NAS backup and recovery jobs for different shares, and a separate container runs for each job.
NAS Container: Docker container running on Protection Engine for NAS data protection.
NAS Agent: Backup and recovery agent for NAS shares.
FSA Agent: Dynamic NAS Protection uses FSA-FBB as data mover for Dynamic NAS Protection. FBB method uses a crawl-and-backup method, which means that it crawls the given file system and backs up files and metadata.
The search cluster consists of one or more Search Engine nodes to index the NAS backup data.
Note: Each search node can index up to 1 billion files. If there are no virtual machine backups configured and only NAS shares are being protected, each node can index up to 1 billion files over single (or different) shares.
