This script has been derived from below VB script:
Robocopy launching multiple concurrent sessions
https://gallery.technet.microsoft.com/scriptcenter/Robocopy-launching-f67faec7
It has been requested by many of my followers/Colleagues to change it to powershell as it sounds easy to do modifications.
So here we go, download & extract the zip file from below location.
https://github.com/VikasSukhija/Downloads/blob/master/SyncRobocopy.zip
Update the Source & Destination in sd.CSV file to mirror using Robocopy
There is a timeout 60 inside the .ps1 script which you can update as per your requirement, this has been done to control the number of sessions.
Every 60 seconds new robocopy session is launched so please time it as per scenario.
We have ran the script from:
C:\SyncRobocopy
if you wish to change this path than please change the it inside the rcpy.bat file as well
robocopy %1 %2 /MIR /copyall /r:4 /w:1 /zb /fp /V /ts | find /i /v “same” >> C:\SyncRobocopy\logs\%3_Share_1.txt
All logs will be saved inside the logs folder , robocopy will only log new files or files that are extra
You can manully run mirr.bat or schedule it as we have done using task scheduler.
Note:- Script has a logic to recycle logs after 30 days.

Hi Vikas, I have used your script and its really working great. Only when file paths in source and destination it fails to recognize. It will be great if you could help in fixing such situations.
Thanks.
