If you are running a Window Home Server you will want to be sure to get in on the upcoming public beta of Power Pack 1. This update will include a fix for the Data Corruption issues that just about everyone has complained about. S
ign up for the public beta now on Connect. Doing so will mean that you will be notified once it becomes available.
Unfortunately the ability to do a
backup of you home server to an external device has been pulled, but I think getting the data corruption bug fixed was more important for them to get right. Hopefully this will make it back in a future release
