i have typed the following inside PowerShell:-

PS C:\Windows\system32> Restore-spsite ?

cmdlet Restore-SPSite at command pipeline position 1
Supply values for the following parameters:
Path: "C:\Users\m.g\Desktop\Backup\Intranet"

Are you sure you want to perform this action?
Performing operation "Restore-SPSite" on Target "?".
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help
(default is "Y"):y

But power shell will raise the following exception,

Restore-spsite : Invalid URI: The format of the URI could not be determined. At line:1 char:1 + Restore-spsite ? + ~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidData: (Microsoft.Share...dletRestoreSite: SPCmdletRestoreSite) [Restore-SPSite], UriFormatException + FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletRestoreS ite

If i understand the error right, power shell is unable to understand the following path C:\Users\m.g\Desktop\Backup\Intranet which contain the backup file, is that right ? and if yes then why power shell did not understand this path ?? Thanks

Restore-SPSite will require two parameters

  • Identity - your site collection url
  • Path -backup path of site you wanted to restore (full file path till .bak)
  • Also add "-Force" attribute Commented Jul 21, 2017 at 7:54

There might be a lot of point where you probably making mistake.

I believe that you need to provide the site that you're restoring to with your command line. So, for example, if you were restoring to http://intranet/sites then your command would look like:

PS C:\Windows\system32> Restore-spsite http://intranet/sites


Did you try to restore to a host header web application?

if so use:

$w = Get-SPWebApplication <your webapp>
Restore-SPSite -Identity <URL of sitecol> -Path <path to backup> -HostHeaderWebApplication $w.Url
