In order to have a copy of my virtual server I was trying to download the vmdk- and the vmx-file using the datastore browser of the ESXi host. It works for the vmx file (2 kB) but not for the vmdk file (125 Gb). In the later case the download seems to start but then I immediately get this error: 'connection to server has timed out' and the download fails.
Any ideas? Or is it simply that the virtual server has to be turned off to download the file? Can't test that right now ...
