    NBD serves as a fallback when other transport modes are not available. The local area network (LAN) can be the production network or a dedicated backup network.

    I have found that restore performance can be noticeably faster with HotAdd.  Try configuring a VSA Proxy and restore using HotAdd Transport Mode.

    Both SAN and HotAdd would be better then NBD generally. SAN needs a physical proxy and HotAdd uses a virtual. 
    • SAN (storage area network) - SAN mode is supported for directly connected storage using Fibre Channel (FC) or Internet SCSI (iSCSI) protocols.
    • HotAdd - In HotAdd mode, the Virtual Server Agent is installed on a virtual machine residing on an ESX Server.
    • Local Area Network (NBD and NBDSSL) - NBD (network block device) & NBDSSL (encrypted NBD) transmit data over the TCP/IP connection between the ESX server and the proxy computer.
