I was part of the beta program for WHS v1 and I have been using it ever since then. I am just now in the process of moving to WHS 2011.
I find it VERY INTERESTING that WHS 2011 sends you an alert saying "Please setup a server backup" or words to that effect
When WHS v1 was in beta and was first released I can remember folks, including myself, complaining to MS that it was ridiculous that WHS won't back itself up. One of the main rasions d'etre of WHS was to backup PCs and yet this product would not let you back up a PC running WHS. Very strange thinking.
MS' response (or at least the response from MS fanbois on the MS community forums) was "There is no need for you to backup your server, just reinstall WHS" which was ridiculous.
It is interesting to see the 180 degree shift!
