ADDITIONAL NOTES

NOTE: This script utilizes 7-zip command line version 9.20 executable file. This version of 7-zip has been identified as being vulnerable to multiple code execution exploits via crafted archive files. Since the executable is only used to create archives, the danger these vulnerabilities pose are negligable as long as the 7-zip executable is only used by the script to create archives. This version of 7-zip is only used because of its ability to be easily downloaded and installed. To easily mitigate the vulnerabilities found in version 9.20, simply download 7-zip version 18.05 or higher, copy the file 7z.exe to the \bin directory, and rename the executable to 7za.exe.

This script uses the 7-Zip program to compress folders for backing up. 7-Zip is licensed under the GNU LGPL license and its source code can be found at https://www.7-zip.org/.
