Hamilton has done the coding to get the XS to back up Sugar on a Stick. We are currently testing it.<br><br>Caroline<br><br><div class="gmail_quote">On Fri, Jun 12, 2009 at 11:52 AM, Mel Chua <span dir="ltr"><<a href="mailto:mel@melchua.com">mel@melchua.com</a>></span> wrote:<br>

up to half a gig (afaik that's back-of-the-envelope how much it gets on<br>
the XO), a classroom of 40 kids = 20GB thumbdrive and 0 data privacy.<br>

Automatic server backup is a feature that's been available for several<br>
months.<br>

I've tested this myself; it works, at least on XOs. I see no reason why<br>
it would not work for SoaS, but have not tried - Caroline may know<br>
better what the status of SoaS with respect to schoolservers is. It's<br>
clunky, and the interface is ugly, but it works. You *do* need engineers<br>
who know what they're doing to make sure it's implemented properly,<br>
though - last time I checked, ease-of-setup hadn't been tackled yet.<br>
