Direct NFS访问模式下的数据备份

Data backup in the Direct NFS access transport mode is performed in the following way:

1. The backup proxy sends a request to the ESXi host to locate a VM on the NFS datastore.
2. The ESXi host locates the VM.
3. Veeam Backup & Replication triggers VMware vSphere to create a VM snapshot.
4. The ESXi host retrieves metadata about the layout of VM disks on the storage (physical addresses of data blocks).
5. The ESXi host sends metadata to the backup proxy.
6. The backup proxy uses metadata to copy VM data blocks directly from the NFS datastore over LAN.
7. The backup proxy processes copied data blocks and sends them to the target over LAN.
