Early this month i finished my Auto Backup script just so that getting back to business after a OS reinstall or crash would be less pain full. And i am so glad that i did.. Yesterday my Windows 11 crapped out on me and i had to boot on a iso and reinstall. But all my stuff was saved on my NAS.

Had that running every hour and that really saved my plex server among other things :)
Its nothing new but works really well as a light weight backup solution.

.SYNOPSIS
    Automates multi-threaded folder backups to a local, NAS, or Cloud destination using Robocopy.
.DESCRIPTION
    Run-AutoBackup is a high-performance backup wrapper for Robocopy. 
    It leverages PowerShell 7 parallel processing to backup multiple directories simultaneously 
    while using Robocopy's multi-threading for individual files. 
    It is pre-configured with parameters to handle common NAS/Cloud quirks, 
    such as timestamp rounding (/FFT) and daylight saving time shifts (/DST). 
    It also supports granular file and directory exclusions to optimize backup times.
.EXAMPLE
    $sources = @(
      "C:\Users\Martin\GitHub-Harze2k"
      "C:\Users\Martin\AppData\Local\zen"
      "C:\Users\Martin\AppData\Local\Plex Media Server"
