POWERSHELL SCRIPT TO EXPORT ALL SITES IN A SITE COLLECTION TO A SEPERATE FILE

I have a requirement to export all sites with in site collection to a separate backup file.  With lots of sub-sites I thought the best way to do this would be with a PowerShell script that utilises the Export-SPWeb command.  So I wrote one!  Here is the script:

<#

 --------------------------------------------

 SharePoint 2010 PowerShell script to export

 all sites within a given Site Collection to

 a separate file.

 File        : ExportSites.PS1

 Revision history:

 -----------------

 1.0 Initial version

---------------------------------------------

 #>

 # -------------

 # Set variables

 # -------------

$SiteCollection = "http://intranet"

$sites = Get-SPWeb -Site $SiteCollection -Limit All

$ExportFolder = "D:\Exports\"

 # ------------

 # Begin export

 # ------------

ForEach ($site In $sites)

 {

$ExportFile = $ExportFolder + $site.Title + ".cmp"

 Write-Host "Exporting" $site.title "-" $site.url

 Export-SPWeb $site.url -Path $ExportFile -IncludeVersions All -IncludeUserSecurity -Force

 Write-Host "Export to" $ExportFile " complete.  File is" (Get-Item $ExportFile).length "bytes." -ForegroundColor "Green"

}

And here is a screenshot of the output, colour coded to make it easier to read:

Feel free to copy the code and use the script as you see fit (at your own risk of course, I can not and will not take responsibility for any undesired outcome).  You may wish to add additional parameters to the Export-SPWeb command such as UseSQLSnapshot, or NoLogFile
