Great suggestion.  I do have the time and the need to learn and the space. The e-biz is running on another server and there is little point in reducing the number since we have a super-duper deal.  Also I have a web programmer personal friend, Carolina Custom Designs, who can help me with modest cost since he is actively working the e-biz (bullion company, WordPress and WooCommerce) end as well.

Sure, later I may move things around a bit, but this is a server I can use for my WordPress and VBulletin and other stuff, often on Bible issues. Right now spread over a couple of other hosts.  And get my skill level up.

OwnCloud, (or Cozy or Seafile, et al) here we come.  (First, I have to get the FTP credentials :) ).

And for an upgrade, from 2.0, of $15 the Emsi thing is included.

Let me try to understand some basics. 
We will discuss Syncovery which is helpful with its Wizard Mode and Advanced Mode settings for creating backup Profiles. 

(Would it be simpler just to set up a free FTP server on one puter and client on the other? Not sure.)

In the Wizard Mode, Syncovery seems to indicate that you have a few methods that could work when dealing with your own remote computers.

Network Path - example given : \\mylaptop\C\Users\pureb\Documents
Browse - File Path (here I presume you have made a WebDav connection for this to apply, if you are working with a remote puter)
Globe --> Internet Protocol Settings --> FTP, SSH, WebDav, AmazonS3, HTTP, also many servers. Note that Amazon S3 and somes others are modest cost for my 15 Gb File if I want to put them in the middle, and if either they take such a large file, or I go into splitting.

(Maybe this WebDav only needs the external IP number and the User-Password? Hmm.. that is pretty loosey-goosey.)

There is also a "Device" that brings up "MTP Device Settings" which seems to be local devices, maybe relates to some media backup.
Note: I remember that Syncovery was pretty smart when I made a WebDav connection to DriveHQ and suggested making their own connection.

So, what specifically do you do? Can Syncovery or CarotDev or something walk me through having the WebDav path connection?  Clearly, that has a big advantage in that your Total Commander or other File Manager is then in play?

If you want to do the FTP with Syncovery, does that mean that you set up a free server and then access it with Syncovery?

Is there a VPN method that creates a Network Path that would be usable by Syncovery?

Maybe a little discussion, or finding a good youtube, can hash out how this is really done without too much complexity.  e.g. When I opened CarotDev, I saw all sorts of blank entry fields, presuming more familiarity than I have.

I realize that I am asking a lot here.  It just seems that there is a gap between the presumed solutions and the place where the not-real-PC-tech people begin.

FYI - I will also mention offhand that Binfer looks comfortable for inexpensive transfer of large files, with a funny email interface and modest cost. I did a couple of small xfers with it, but for clear communication I ended up opening two free accounts, with file limits. It is unclear then if both would need to be paid accounts. Also the software seems to be somewhat dormant the last five years. However, it might do a 15GB direct file transfer quickly for $5 or $10 as part of a 40Gb package. 

A whole nother possibility involves simply using a server I have, as of today, available for WordPress and such. Presumably that would be an easy FTP in triangle mode. Why do I have a server for that? Well, a biz e-commerce operation had three, with lots of redundancy, and very inexpensive. So we cleared two out and I inherited one :) .
