After hearing stories of folks losing their progress due to game crashes and whatnot, I thought it would be a good idea to have a way to automatically backup character and world saves. So I modified a program I made to automatically backup saves for a different game, and Valheim Save Shield (VSS) was born!

When you run VSS, it automatically monitors your Valheim saves for changes and then makes a backup of the changed saves. If you need to restore a backup, just select it in the list, click the restore button (the loopy arrow in the screenshot), and it will be restored to your active Valheim save folder.

You can turn off automatic backups (I don't know why you would, though), set the minimum number of minutes between backups, and the maximum number of backups to keep for each character/world. Note: the game only saves characters and worlds once every half hour 20 minutes. You can set the "minutes between backups" to a lower number than this, but backups will only be made when there's a new save to back up. Be careful about setting the maximum number of backups to keep to a high number, because it will take a lot of storage space. Don't change the save folder unless you know what you're doing. It should automatically point to your Valheim save location.

Feel free to browse the source code on GitHub. If compiling yourself isn't for you, you can download the latest .exe there as well.

Happy adventuring!
