Minecraft Servers UID Extractor

A batch script to automatically search and back up Minecraft server files based on specified UIDs, preserving folder structure without modifying the original files.

This script is designed to automate the backup process for Minecraft server files by searching for specific UIDs (unique identifiers) within a source directory and copying matching files to a destination directory, while preserving the folder structure. Here's a detailed explanation of what it does:

Features of the Script:

1. Source and Destination Directories: The script prompts you to input the source directory (your Minecraft server folder) and the destination directory (where you want the backup).
2. UID-based Search: The script searches for files that match the given UIDs (user-defined identifiers) in the source directory. It does not take file extensions like .dat, .yml, or .json into account; it looks for any files whose names include the specified UIDs.
3. Folder Structure Preservation: The script ensures that the same folder structure is recreated in the backup destination, meaning the files are copied into their corresponding subdirectories in the backup location.
4. Non-destructive: The script does not modify or delete any files in the source directory. It only copies the matched files to the destination.
5. Status Display: It will display a message indicating whether any files were found and backed up for each UID, or if no files were found for the given UID.

Example:

If your source directory is structured like this:

minecraft-server>world>playerdata> 12345678.dat 12345678.dat_old qwertyu.dat qwertyu.dat_old

And you give the UIDs 12345678, the script will:

• Search for any files containing 12345678 in their names.
• Copy 12345678.dat and 12345678.dat_old to the destination directory, preserving the folder structure.
• It won’t copy qwertyu.dat or qwertyu.dat_old.

Script Walkthrough:

1. Input Prompts:

   • Asks for the source directory where your server files are located.
   • Asks for the destination directory where the backup will be stored.
   • Asks for the UIDs (can be multiple) that you want to search for in the files.

2. Directory Validation:

   • If either the source or destination directory does not exist, the script shows an error message and exits.

3. UID Search:

   • For each UID entered, it searches the source directory and its subdirectories (for /r) for files whose names contain the UID.
   • If a match is found, it will:
     • Create the same folder structure in the backup directory.
     • Copy the matching file to the backup directory.
   • A status message is displayed for each UID:
     • "Files for [UID] were found and backed up."
     • "No files found for [UID]."

4. Backup Completion:

   • After all UIDs are processed, the script displays: Backup completed.

Example Run:

• Source: D:\serverdirectory\minecraftserver
• Destination: D:\backup
• UIDs: 12345678

The script will search for files containing 12345678 in the minecraftserver folder (like 12345678.dat and 12345678.dat_old), copy them to the D:\backup directory, and preserve the folder structure.

Instructions:

1. Save the script as backup.bat.
2. Double-click to run the script.
3. It will ask you to input:
   • Source directory.
   • Destination directory.
   • UIDs to search for.
4. The script will perform the backup operation based on your inputs.
