Answer 1

You are running the command from powershell:

• use either the sharepoint management shell (under the Sharepoint start menu)
• or load sharepoint in powershell "Add-PSSnapin Microsoft.SharePoint.PowerShell" (see: http://social.technet.microsoft.com/Forums/en-US/sharepointadminprevious/thread/fcb77654-0f13-42e0-b181-6e52242fe9d6)
• or in ISE: see: http://www.harbar.net/archive/2010/05/03/adding-sharepoint-2010-poweshell-cmdlets-to-your-powershell-ise.aspx

Are you using Windows PowerShell or SharePoint Management Shell? This is however an old question and here you may find something useful: End user site backup
