This script synchronizes one or more source directory/-ies (variable $sourceDirs) with one destination directory (variable $destDir) recursively. The script will not create a new version folder for each mirroring process. Instead the source directories will be synced with the same destination every time. The directory structure of the source directory/-ies will be mirrored 1:1 in the destination directory. Before the sync process starts the availability of the target and the source directory/-ies is tested. Any changes made to the source directory will be applied to the destination directory. Internally, powershell prepares the mirroring process and Windows' robocopy does the actual work. All activities are logged in a seperate log file (variable $logpath). View the ps1-file for more information.

powershell.exe -noexit -Mta "sync_files.ps1" [auto] [shutdown] [logginglevel]

-auto: The script runs without user interaction. If not provided the user will be prompted to confirm.
-shutdown: System shutdown immediately after the script has terminated. Even if an error was thrown.
-logginglevel: (1) Only write to logfile (2) Write to logfile and display in console (default)

1. Set the variables $sourceDirs and $destDir to your desired directories.
2. Launch the script using the command and the optional paramters above

I recommend hooking up the command to the windows task scheduler together with the -auto parameter or to call the script manually via a shortcut along with the -shutdown parameter.
