It depends, if acronis works similarly to Paragon's backup tool and is WinPE based, it should work OK. Just copy an iso of the DVD to your datastore and configure your VM's DVD Drive to use that iso (or use the Client's or Host's DVD Drive with the Acronis DVD inside), make sure it is enabled and set to boot first from there, and then you'll boot into the Acronis DVD. Now you should be able to map to your LAN, and if that works you will be able to restore your images from the LAN to the VM you are booted into.
