I wanted to backup my projects directory to an external drive. Every time I run the backup operation it should automatically sync the source and the destination, including deleting any files at the destination that are no longer present at the source. Here’s how I did it on Windows:
- Create a batch file (*.bat) with the following inside:
robocopy C:\projects D:\projects /mir /xd node_modules .git/mir is for mirroring.
/xd node_modules .git is to exclude specific directories.
- Using Task Scheduler, set up a recurring task with the action “Start a program”, pointing to the .bat file
