I'm using Portal for ArcGIS 10.5.1 and I've a hosted ArcGIS server with ArcGIS Data Store configured. I don't have a standby environment. As I understand it I can get a complete backup of the enviroment (webgisdr) and restore the environment. But if I just have one hosted feature layer that needs to be restored? What options do I have? How should I set up things to be able to restore single hosted feature layers?
