At one point in time, I found myself needing to move data from one server to a new server. Often times this happens when replacing a server. So the server had about a terabyte of data on it. Pretty small, considering. But there were hundreds of thousands of files and folders.
I could just copy this data using Windows Explorer, but that isn’t as fun! I set out to build a script to copy this data and I used Windows built in utility called Robocopy.
This utility is epic. There are so many things you can do with it. I’m going to highlight just a few for you.
Copy all data subdirectories and all files
robocopy.exe <source> <destination> /mir
Copy data over a network connection
To copy data over a network connection, sometimes the connection gets interrupted, the robocopy tool can automatically retry using the following command:
robocopy.exe <source> <destination> /mir /r:[number of times to retry]
Copy data with all NTFS ACLs and Owner Information
robocopy.exe <source> <destination> /copy:DATSOU
Copy data while deleting directories in destination that do not exist in source
robocopy.exe <source> <destination> /purge
Copy data while capturing a log file
robocopy.exe <source> <destination> /mir /log:<path>
Copy data while appending to a log file
robocopy.exe <source> <destination> /mir /log+:<path>
Stay tuned, I’ll had more functionalities here as soon as possible.
