A simple auto-backup solution- what's yours?

It turns out Windows will sometimes re-jigger the absolute path in a shortcut, if the path to which the shortcut points doesn't exist and it does exist on the current drive.

Nevertheless, I wouldn't rely on shortcuts either.

I have used Robocopyxp for many purposes as well as large data transfers at work.

I wrote a batch script that will backup your USB Flash Drive (should work fine with a USB Hard Drive as well) to your Main Hard Drive

The way the script is organized now is assuming you dont have MASSIVE amounts of data.
This script requires the following:
1) USBackup.bat (the code below is this file)
2) 7z.exe (this is the opensource application called 7-Zip, the 7z.exe file is the command executable of it)
3) Robocopyxp.exe (this is the Robust File Copy Utility from Microsoft. Its free, but not opensource. I dont claim any ownership over it, just that my script calls it to run)
4) Deltree.exe (This is a Tree deletion utility I found online, honestly, I dont know what its licensing status is, the web site where I found it is located HERE )

All these files are put in a folder called Apps\USBackup on the removable drive.

Here is the code:
