Config Backuper
by NaoCraftLab
Config Backuper is a client-side utility that copies game and mod configuration files into backups whenever Minecraft starts.
What it does
On launch the mod saves copies of game configurations, mod configurations and shader configurations, so a broken edit can be rolled back by restoring an earlier copy. Backups are compressed to keep their size down, and older ones are removed automatically so the folder does not grow without limit. Only the client needs it; a server can run without it, and single-player players get the same protection.
Files are published for Fabric, Forge, NeoForge and Quilt, covering 50 release versions 1.7.10 – 26.3, with snapshot builds also published. The latest files are 1.0.1 for 26.3 on Fabric and Quilt and 1.0.1 for 1.21.11 on Forge and NeoForge. The code is open source under the MIT License, and the source and issue tracker are public.
Key features
Configuration backups at launch
Each start of Minecraft saves copies of the configuration files, so the previous state is kept before any change.
Game and mod configurations
Both the base game settings and the settings of installed mods are included, along with shader configurations.
Compressed archives
Backups are stored compressed, which reduces the disk space each saved copy takes up.
Automatic cleanup
Old backups are removed so that only recent copies remain in the backup folder.
Compatibility
Latest build for each game version and loader.

Use cases
Rolling back a broken edit
After a configuration change stops a mod from loading, an earlier copy from the backup folder can be restored.
Testing mod settings
Before trying a new set of options, a player keeps the working configuration in a backup.
Who it’s for: Players who edit many mod configurations and want a saved copy from each launch. It suits single-player worlds and the client side of multiplayer play.
