Restore files from a duplicated image

Hi, 

I am writing some kind of FAT for duplication features.

The scenario I have is the following one:

In one site (SITE 1) a make a backup of a windows client and then a make a duplication to a MSDP disk.

In the SITE1 there are two media servers: mediawin and mediawindup.

What I want to do is to shutdown mediawin and recover the backup from mediawindup.

When mediawin is powered on a can see both media servers and I can recover from mediawindup, but when it is powered off in the tab of media server appears "default", a cannot select anything and the restore fails...

What is wrong with this scenario?

Thanks
