Duplicate Disks available for restore

When i go to restore from a particular server, I see duplicates of the same disk.

For eg.

C: [servername.domain [C]]

C: [C:]

E: [servername.domain [/E]]

E: [E: [volume1]]

F: [servername.domain [/F]]

F: [F: [volume2]]

I see the same restore content from each instance of the same disk.

Any explanation for this?

thanks.
