1. Log on to the SharePoint server as the administrator.
2. Open a command window and run the following command:

       Stsadm --o backup directory c:\bkup --backupmethod full

3. Open the c:\bkup folder and verify that it contains a newly created folder starting with “SPBR” and an index number.
4. Open SharePoint Central Administration, and switch to the Operations page; click “Backup and restore history” in the Backup and Restore section. The backup process you started in step 2 should be listed here.

When running this backup process, you will see a lot of details listed. To stop STADM from showing these details, add the command switch “-o quiet” at the end of step 2.
