The program was written in Python 3.12.4 (versions up to 3.9 should also work) and the flet framework. It is better to download it from requirements.txt using the command:

For Windows:

pip install -r requirements.txt

For Linux and macOS:

pip3 install -r requirements.txt

Then run the main.pyw file using the command (or by double-clicking):

For Windows:

python main.pyw

For Linux and macOS:

python3 main.pyw

Basic

Creation

All data that you have entered during creation are stored separately from the backup file.
To change backup data, press and hold the left mouse button.

Note

Clicking the backup name will open it in the file explorer.

Backup data

File name - the backup file name, by default is the world name. The creation date and .zip extension will be added after creation.

Note

This cannot be changed after creation.

Title - backup title, optional field.
Pool ignore - when checked, the backup is not included in the pool.

Backup pool

The pool (queue) automatically removes outdated backups. By default, the pool is set to 4. This means if you have 4 backups (with the Pool ignore flag unchecked) and create a new backup, the oldest one will be deleted.

Note

The program determines the oldest backup by the date that the user has entered.

Restoring and deleting

When restoring, the world folder will be permanently deleted and replaced with the folder from the backup.

Important

The program will immediately restore the world without popup windows.

When deleting, the backup file will be removed.

Important

The program will immediately delete the backup without popup windows.

Backup structure

All backups from the saves folder are saved at <backups>/saves/<WorldName>/backups. From the versions folder at <backups>/versions/<VersionName>/saves/<WorldName>/backups.

<backups> - the folder where all backups are saved (can be changed in settings). <VersionName> - version name.
<WorldName> - world name.
backups - folder where world backups are saved.

Note

Names are taken from folder names, so they may be different from what you see in the game.

Tip

To get the name of the world folder, in select world menu you can look below the world name, or you can open it when editing the world.

Features

The program can automatically determine the backup creation date (if it is formatted like YEAR-MONTH-DAY_HOUR-MINUTE-SECOND), so you can transfer backups created with Minecraft.

Note

Backups that have been transferred in this way will be included in the pool.

Localizers

GNU gettext is used for localization. To add a new language, you need to create a subfolder with the language code (example assets/locale/pl/LC_MESSAGES). Then copy template files(with .pot extension). After filling in templete you can create pull request (make sure to add .mo extension to .gitignore).
