About
FastBack protects Minecraft worlds by creating Git-powered incremental snapshots that save only changed files, making repeat backups faster and smaller than full zipped copies. You can make backups locally or send them to a Git server or a network volume, schedule them around shutdowns or autosaves, and restore a snapshot as a separate world without overwriting the current save. Commands also let you list and delete snapshots, apply retention policies such as daily, fixed-count, or GFS, and prune old backups to manage storage. Backups can optionally include mod jars and configuration files, and dedicated servers can broadcast a notice when a backup is starting.
Written from Modrinth . How we write it
In-game changes
Changes the game's code in 3 areas: User interfaceChanges 1 game code file in this area: menus, screens, tooltips, the chat window and the in-game overlay., Game coreChanges 1 game code file in this area: the main loop, lighting and other code the whole game uses. and Server and world logicChanges 1 game code file in this area: the world, commands, scoreboards, saved data and game rules..
Libraries packed inside it change 15 more game code files: Packet Tweaker and Server Translations API.
Adds no new blocks, items or other content.

No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Accepts connections from other computers
- It can accept connections from other computers. Found in org.eclipse.jgit, a library it includes.
- Uses folders outside the game
- It can read or write files outside your Minecraft folder, on the rest of your computer. Only in its files for Fabric 1.21.1 to 26.3; NeoForge 1.21.11 to 26.3.
- Starts other programs
- It can start another program on your computer, for example to open a link in your browser. Found in the mod's own code and in 4 libraries it includes.
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. Found in 3 libraries it includes. See Privacy
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.31 latest files: the newest file for each Minecraft version and loader. The answer above is about the 20 for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Starts other programsPurpose not known.
- Looked for, not foundWe looked for these in the file and did not find them.Updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends
We read its code without running it: it contacts no web address while you play.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of all 20 files, for recent Minecraft versions. See each file in Releases
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
No sign so far that AI was used to make it
We looked for AI tools in its texts, files and images and found none.
We have not read its code history yet.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Not read yet
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found2 of 40 changelogs read
- Its filesFiles that AI coding tools leave behind (like AGENTS.md), and the texts inside the files you download.Nothing found
- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Nothing found1 image read
- Code of the modThe code and files of the mod, read without running it: addresses of AI services, AI libraries, AI model files and a place for your own AI key.No AI service, AI library or AI model file290 code files read
