In ArcGIS server administrator directory, I am using export tool to take a backup for my site. Now I am trying to do schedule for this tool to take a backup automatically in a specific time. Can I find this tool as python code to make this schedule?
You can use ArcGIS Server's Backup Utility:
Backup utility—ArcGIS Server Administration (Windows) | ArcGIS Enterprise
The above link has a python snippet.
