Also make sure that you present the LUNS that your VM's are located on to the Proxy (Server with the Virtual Server iDA installed)
These will show up in Disk Management with no drive letter and will be marked as offline.
As a test you could also test backing up the VM using the auto method instead of selecting the san method to verify you can connect and back it up. The auto method will try san first then will try nbd (Network Mode) as a failback method.
