Sorry, but I don't get it.
I have GUI and Production in Datacenter A.
I have mount server and backup in Datacenter B.
Now I start the restore procedure using GUI in A for the backup in B.
OK, it will use the mount server in B. But it will copy only to either production (in A) or the GUI server (also in A). I need it NOT to use the link A<->B, but get me access to the files in B directly.
