Backup and Restore Site Collection in SharePoint - Migrate to new Site Url

- Using stsadm command

/*stsadm.exe -o deletesite
-url
-deleteadaccounts */

24: -filename
25: [-hostheaderwebapplicationurl ]
26: [-overwrite]*/

- Using Data Object Model

public static void BackupAndRestore()
{
// Get a reference to the Web application publishing
// Web service.
//SPFarm myFarm = SPFarm.Local;

using (SPSite site = new SPSite("http://vinh:2804"))
{
// As alternative to the preceding three lines, you can use
// the following when you know the URL of the Web application:
// SPWebApplication myApp = SPWebApplication.Lookup(url_of_Web_app)

// Get a reference to the Web application's collection of
// site collections.
SPSiteCollection mySiteCols = site.WebApplication.Sites;

// Back up a specified site collection.
mySiteCols.Backup(@"http://vinh:2804/sites/Dev123", @"c:\data.dat", true);

using (SPSite site123 = new SPSite("http://vinh:2804/sites/Dev123"))
{
Console.WriteLine(site123.ID);
site123.Delete();

}

// Restoring the site collection is identical to the preceding
// code except that the "Restore" is used in place of "Backup".
//
mySiteCols.Restore(@"http://vinh:2804/sites/Dev", @"c:\data.dat", true);

using (SPSite site123 = new SPSite("http://vinh:2804/sites/Dev"))
{
Console.WriteLine(site123.ID);
}
}
