When attempting to back up our Portal (11.1) I received the following error:
{"error":{"code":500,"details":null,"message":"Failed to export site. Export of the Portal repository failed. The content directory has no properties.json file under the portal directory."}}
On our Portal server under C:\arcgisportal\content there is no 'properties.json' file. There is only a folder called 'items' and a file called 'site-key.json'
Does anyone know how to generate that file or why it could be missing?
