In Microsoft documentation, Microsoft dosen't say what folder is considered by snapshot. But , she say : any data outside '/home' is not persisted , when open a ssh terminal on the web app using Kudu.
So, if i have an azure web app custom docker image with premium sku , which he run a application stored under /var/www/html and this application store log file in /home/site/wwwroot ( option websites_enable_app_service_storage is already changed to yes )
My question is : when using snapshot to restore web app , should i found all content in the web app ? Or only the file stored in /home ?
It looks like your question was answered in this Github thread.
Adding to Ajay's answer- Snapshots contain both the contents of a web app and the web app configuration. Your app files content can be found in the D:\home\site\wwwroot folder of your app.
