Hey Rohail. If your standard Tableau Server host machine (or machines) is down, and you can't get it fixed in a timely fashion, you will need to get a new host machine set up, then install Tableau Server and use the tabadmin restore command to take your .tsbak file and reload all your content onto the new server.
Does that answer your question?
