The Witcher 3 | SaveSwitcher 2 - Ultimate

click setup.exe to install - .Net 4.7.2 required to run

Profile manager to create and switch out multiple save profiles for games that do not provide that possibility by themselves.
Default settings are aimed at The Witcher 3 but the app should work with any game theoretically.

Profiles can be created producing a backup of the active savegames. 

The game has to be launched through the SaveSwitcher. That way the backup is synchronyzed automatically whenever the game is closed. 
There also is the possibility to sync the backup manually using the update button.

The app is especially targeted at handling the problem of online synchronysation of different savegames e.g. by GOG Galaxy. This can happen 
if multiple people use the same game license.
If the app recognizes that the savegame has changed during off time (probably because of syncing) your old save is still present by its backup.
The new savegame can then be stored in a different profile. That way no data is lost.
