PowerShell Surgical File Restorer

A specialized PowerShell script designed to replace specific files on a "Live/Corrupted" drive with healthy versions from a "Recovery/Backup" drive.

🚀 Use Case

This script is ideal for scenarios like Ransomware Recovery or Data Corruption. Instead of a bulk restore that might create duplicates or clutter, this script reads a list of specific filenames (e.g., from a log or a specific directory export) and performs a 1-to-1 replacement only if the file already exists on the destination.

🛠 How it Works

1. Source (Z:): Your Backup/Recovered drive (e.g., a mounted Veeam backup).
2. Destination (W:): Your Live/Target drive containing the corrupted or encrypted files.
3. The Logic:
   • It reads a text file containing relative paths.
   • It checks if the file exists in the Source.
   • It checks if the file exists in the Destination.
   • Crucial: It only performs the Copy-Item if the file is found in both locations, ensuring a 100% precise replacement.

📋 Instructions

1. Prerequisites

• Create a file named files.txt on your desktop.
• List the relative paths of the files you wish to restore (e.g., folder\subfolder\document.docx).

2. Configuration

Open the script and modify the following variables to match your environment:

• Paths: Change the paths for log.txt and files.txt.
• Drive Letters: Adjust $src (Source) and $dst (Destination) variables.
• Path Logic: Adjust the -replace logic if your source folder structure differs from your destination.

3. Execution

Run the script in a PowerShell window with administrative privileges.

⚠️ Disclaimer

This script uses the -Force parameter to overwrite files. Always ensure you have a secondary backup before running mass-replacement scripts.
