How about private backup network?
Seeing how slow backups are over 1GbE I'm interested in connecting my Linux servers to the backup server via private 10GbE. These addresses would be non-routed, 10.1 addresses. Is this straightforward to do?

It is.

As long as you update the host files correctly there should be no challenge.
One point important is that, if this leaves the server with multiple IPs, then make sure that the backup interface is the first entry in the host file. The same holds for storage node and clients.

An alternative would be to use a different naming convention, e.g. server_name-bkp or similar.

It would be preferred to use DNS. If not, hosts can be updated and there is no reason at all to use first entry as backup one; you simply create entry for backup interface with its IP and make sure storage node and client know about it (and so should server about clients).

This is very straightforward. I always recommend a private network for backup traffic. I agree with using DNS instead of host files, that is easier to support in a large environment or as one grows. One thing to consider, can your hardware truly take advantage of a 10GbE card? You may want to test in a PoC first. You don't want to spend the money and find out you can only get 2.5 Gb/s out of your 10 GbE card because the hardware just can't drive it any faster.
