Dear Sir,
I will reset windows 10 with clean wipe. Please guide how to take backup and restore vtscada light

Option 1:
Just copy the application folder out of the VTScada directory for any applications you want to keep. You can copy the entire VTScada directory to be safe.

After reinstalling videos, paste the application folders back into the VTScada directory and you will be able to add the applications back to the VAM without losing any data.

Option 2:
Setup a redundant server for all the VTScada/VTScadaLIGHT applications you wish you backup and let the backup server sync everything, from there you can just wipe the PC and re-add the application later using the Get From Workstation option in the advanced tools when creating a new application.
