We can run the command, given below to restore the site collection-

  1. Restore-SPSite -Identity "http://sharepoint2016:51000/sites/RestoredSiteColl" -Path "C:\BackUp\SiteCollBU.bak"

-Identity: Site collection URL to where the backup will be restored. This site collection need not exist. It will be created during the process.

-Path : Location of the backup file.

However there is a caveat, a content database can have only one copy of the site collection. Thus, if the Web Application has only one content database and we are trying to restore the site collection to the same Web Application, we will get the error, shown below-



In order to resolve this, make sure that there is an additional content database other than the content database of the original source site collection.



Running the Restore script has now run to the completion.



Let’s check out the restored site collection.
