Ron,
A couple of starting questions:
- What is the size and latency of the network pipe between the primary and backup servers?
10Gb WAN. Don't know the latency.
- What is the size of the database you need to restore?
6.5TB dump directory, 3.0TB data/base directory.
- Is there a reason not to do a network copy of the backup directory contents to the database server and run the pg_restore locally?
Option #3!!! I'll research that.
Cheers,

Pg 9.6.9 on Linux...
Given a backup server storing a "format=directory" database backup, and a database server, should I:
Option #1: run pg_restore on the backup server and "push" the data to the database server via port 5432, or
Option #2: have the backup server serve the dump directory via NFS, and run pg_restore on the database server, pulling the data via nfs protocol?
(It'll be a multi-threaded restore over a 10Gb pipe.)
