Backup all sharepoint from a site and restore to another site

These are the steps that I took:

1. Run in command prompt as Administrator:

stsadm -o backup url http://server1:8345 -filename "C:\Temp\backup8345.bak"

2. Go to Central Administration -> Application Management -> under SharePoint Web Application Management -> click Create or Extend Web Application

3. Run in command prompt as Administrator:

stsadm -o restore -url http://server1:9291 -filename "C:\Temp\backup 8345.bak"
