Minoria is really easy and safe:

C:\Users\*your pc user name*\AppData\LocalLow\BOMBSERVICE\Minoria\saves

There, zip or rar the Minoria folder with any number and name desired, after any save in Feather saves.
You can go back to any moment in the game by overwriting the current Minoria folder (backup it first to be safe too), with any older save you made before.

-- *pcgamingwiki . com* is a safe site that documents the saves places, configuration files, and various fixes and quality updates for most known games.

---- For other games:
All save to certain places:
- Most in users-appdata folders: usually under the game studio name
Local
LocalLow
Roaming

- In some cases on C:\Program Files (x86)\Steam\userdata\*your steam user number*\*id number of the game*

- Very old games, inside the game folders

- Documents
- Saved Games
- Unity games, rare times in data folder.
Note:
( Some Unity games -NOT Minoria- even save the game in the *regedit*, usually under the game studio name or other name, but beware with regedit, only go there if you are knowledgeable on how to export/import .reg files as it is a critic system file, you have been warned).

Enjoy !
