BackInv
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
BackInv 1.1
A simple player backup mod for your server.
Work in single player.
I am a technical administrator of the server and encountered the problem that on Fabric 1.21, there is only Death Backup, which is not very server-friendly.
Commands:
/backinv <target>- Opens a graphical interface listing the player's backups (Recommended)./backinv reload- Reloads the configuration file (config/backinv/config.json) without restarting the server./backinv list <target>- Displays a text-based list of the player's backups (No GUI)./backinv load <target> <index>- Loads a specific backup into the player's inventory./backinv inv <target> <index>- Opens a GUI preview of a specific backup for the player.
Configuration
The configuration is located in <game or server directory>/config/backinv/config.json.
