Indeed copying Linux files to Windows OS we don`t preserve the attributes(just like Linux does by default).
To restore with attributes, you need to set ssh and have tools installed on the guest (VMware or Hyper-V should provide guests` ip address to connect).
Credentials asked are for the guest you did backup from.
Also you can add a temporary host while making Linux file-level restore and CopyTo there. In this case attributes will also be preserved since the copy will be from Linux to Linux.
