Automatic save backups!

Backups your save files when entering the main menu. This means that it makes a backup of them when launching the game and when you enter the main menu from the game with the "Back to menu" button.

Backups your save files right before the save function overwrites them. This affects both manual saving with my Manual Save mod and autosaves!

The backups are saved in %LOCALAPPDATA%\Solarpunk\Saved\SaveGames\Backups. You can go there by copy pasting the path in Window's Explorer address bar or by replacing the "YourUsername" text with your actual username in this path:

C:\Users\YourUsername\AppData\Local\Solarpunk\Saved\SaveGames\Backups

The backups are sorted in folders by date and then in folders by time.

Notes

Be aware that depending on the size and quantity of your save files the backup folder might accumulate in size so you probably want to eventually delete some of the older backups. The save files are only a couple of kilobytes though so it should take a while to become an issue. I chose to leave it this way because there's always the chance that you might need an old save.

Installation

Download and install UE4SS Solarpunk.

Download the mod and extract its .zip file.

Go to where your game is installed and navigate to \Solarpunk\Binaries\Win64\ue4ss\Mods\.

Drop the SaveBackups folder from the mod in there.

In the end it should look like this:

\Solarpunk\Binaries\Win64\ue4ss\Mods\SaveBackups\dlls\

Troubleshooting

If you have any issues with the mod you first need to make sure that ue4ss is running. Navigate to \Solarpunk\Binaries\Win64\ue4ss and look for a file named "UE4SS.log". If there is no such file and you've already ran the game then that mean that UE4SS was not installed correctly.

If there is, you can open that file with a text editor like Notepad and check for errors. If the mod is installed correctly and UE4SS is loading it then you should see something like this in it:

[2026-06-14 00:17:08.1142345] Mod 'SaveBackups' has enabled.txt, starting mod.
[2026-06-14 00:17:08.1142727] SaveBackups by yakuzadeso

If not then you probably didn't install the mod correctly.

If you want you can upload the contents of that file on Pastebin.com and then share the pastebin link in a comment explaining your issue.
