I first ran into this question on my Linux Mint (with Mate window manager) install recently.
But I think it applies to Media Center generically, so I'll ask the question here. Mods, please move as appropriate.
OK, here's my scenario.
I have a Windows desktop, appropriately named in Windows as Bloat, that functions as my Media Server.
There also are two Media Center Clients, one on Windows 10 PC which sits in the entertainment center. fwiw, the performance of that Media Center install has been nothing less than flawless from day 1. Thanks for that.
The other Media Center client is the aforementioned Linux Mint install. I've had some issues (with all apps) with the Cinnamon window manager on Linux Mint, but now that I've moved to the Mate window manager, everything seems to have settled down into a reliable client. Media Center (and the other apps I use) seem to be quite comfortable with Mate.
OK, after that wandering, to the point of this comment ...
When I want to do a Library backup on the client for disaster-recovery reasons...
In Media Center, I go to File>Back Up Library
Currently, "Bloat" is checked. That's the Media Center server.
OK, my question ...
Should I check "Main Library" instead, to reflect the Media Center client for backing up?
My goal is to be able to do a Library Restore and have the current client configuration, including the check on Bloat Library restored.
(I realize that passwords will need to be re-entered, and I do consider that to be a security benefit. Thanks for that.)
When I want to do a disaster recovery backup on a Media Center client, which Library should be checked?
