🤖 Robocopy Backup Script

Use Windows' robocopy command to sync your files to the destination of your choice (e.g. OneDrive, Dropbox, etc.)

Setup

1. Download this repository:

   git clone https://github.com/juangutierrez01/robocopy-backup-script

2. Open settings.json in a text editor and fill in the source and destination fields with the corresponding paths:

   {
       "Backups":
       [
           {
               "Name": "Example Backup",
               "Source": "C:\\Users\\YOUR_USER\\Documents\\ORIGINAL_FOLDER",
               "Destination": "C:\\Users\\YOUR_USER\\OneDrive\\BACKUP_FOLDER"
           }
       ],
   
       "LogDirectory": ".\\"
   }

3. Save your changes

4. Right-click on the file robocopy.ps1 and select Run with Powershell to start backing up your files. To make it easier to run in the future, consider making a shortcut to the script as outlined in this guide: https://www.tenforums.com/tutorials/97162-powershell-scripting-run-script-shortcut.html

How it works

The underlying mechanism is the command, robocopy:

robocopy "Source" "Destination" /log+:"LogFile" /tee /mir /z /j /mt:1

"Source"	The directory you want to backup.
"Destination"	The path to your OneDrive/Dropbox/etc.
"LogFile"	The file to store the status output of robocopy.
/tee	Option to display the status output to the console window and store it in the log file.
/mir	Option to mirror the source directory tree.
/z	Option to copy files in restartable mode. In restartable mode, should a file copy be interrupted, robocopy can pick up where it left off rather than recopying the entire file.
/j	Option to copy files using unbuffered I/O.
/mt:1	Option to create multi-threaded copies with 1 thread.
