Creates a scheduled task to backup mylar3 using robocopy.

Robocopy-CreateMylarBackup.ps1

##############
# Mylar Backup using built-in robocopy. This creates 2 files, MylarRobocopyBackup.bat and MylarRobocopyBackup.ps1. The bat file is just used to call the .ps1 due to task scheduler not liking native .ps1 fiels somehow in 2023. 
# The .ps1 file will stop the docker mylar3 container and then run robocopy on the db and ini files, then start the container back up.

# Dump the backup portion of the script.
