The option you have selected for the redirection seems to be fine ... Make sure the account you are using to permform the restore has proper rights and permission to proceed with the restore i.e the accoutn should have an active unique mailbox , should have the exchange full administraot role , member of domain admin group , should have send as and recives as rights etc
Also the make MAPI cdo is installed on the exchange 2007 server and mangement console installed on the media server .
Incase if ou have the backup on tape,it would be better if you duplicate the backup set to b2d so it does not have stage every time you run the restore .
