Veeam backup proxy on site in China, Windows guest on ESXI 5.1 host.
I haven't logged this as technical issue as I'm not sure I have a technical issue, but rather me being new to the software, I've missed something obvious.
Need to restore files from a virtual fileserver on the same ESXI host. Run through the wizard to select Guest Files (Windows). Start the process, loads the Backup Browser window, spins for a little while

and then fails with the error.

The link we have to the China site is slow (2MB) and I think this is part of the problem, but I don't know of any other way to restore the data. Can anyone help?
Thanks
Matt
