Ron,

A couple of starting questions:

1. What is the size and latency of the network pipe between the primary and backup servers?  
   

10Gb WAN.  Don't know the latency.

1. What is the size of the database you need to restore? 
   

6.5TB dump directory, 3.0TB data/base directory.

1. 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,

- Evan

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.)
