Check the size of SharePoint 2010 - 2013 sites using PowerShell

 

One of those “it may come in useful one day” scripts. It walks through a site hierarchy in SharePoint 2010, reports the size of each one, and then displays a total size for all sites reported. It uses the concepts of the code specified in this article, which calculates the size of a site by adding up the contents of each folder within it.

To use, first run the following script:

function GetWebSizes ($StartWeb)

{

    $web = Get-SPWeb $StartWeb

    [long]$total = 0

    $total += GetWebSize -Web $web

    $total += GetSubWebSizes -Web $web

    $totalInMb = ($total/1024)/1024

    $totalInMb = "{0:N2}" -f $totalInMb

    $totalInGb = (($total/1024)/1024)/1024

    $totalInGb = "{0:N2}" -f $totalInGb

    write-host "Total size of all sites below" $StartWeb "is" $total "Bytes,"

    write-host "which is" $totalInMb "MB or" $totalInGb "GB"

    $web.Dispose()

}

function GetWebSize ($Web)

{

    [long]$subtotal = 0

    foreach ($folder in $Web.Folders)

    {

        $subtotal += GetFolderSize -Folder $folder

    }

    write-host "Site" $Web.Title "is" $subtotal "KB"

    return $subtotal

}

function GetSubWebSizes ($Web)

{

    [long]$subtotal = 0

    foreach ($subweb in $Web.GetSubwebsForCurrentUser())

    {

        [long]$webtotal = 0

        foreach ($folder in $subweb.Folders)

        {

            $webtotal += GetFolderSize -Folder $folder

        }

        write-host "Site" $subweb.Title "is" $webtotal "Bytes"

        $subtotal += $webtotal

        $subtotal += GetSubWebSizes -Web $subweb

    }

    return $subtotal

}

function GetFolderSize ($Folder)

{

    [long]$folderSize = 0  

    foreach ($file in $Folder.Files)

    {

        $folderSize += $file.Length;

    }

    foreach ($fd in $Folder.SubFolders)

    {

        $folderSize += GetFolderSize -Folder $fd

    }

    return $folderSize

}

Once you have run the script, you can call it with the following PowerShell command:

GetWebSizes -StartWeb <StartURL>

Using a start URL allows you to perform a size check from any site in the hierarchy – not just the top level site. In the example below, I ran it against the URL http://portal, but could also choose to run it from a sub-site, if required:

PS C:\> GetWebSizes -StartWeb http://portal
Site Intranet is 12763801 KB
Site Hello is 581759 Bytes
Site Team Site is 604175 Bytes
Total size of all sites below http://portal is 13949735 Bytes,
which is 13.30 MB or 0.01 GB
