You read that correct you have only 5 more days to get all of your data off your Vail machine! On January 10th 2011 the public preview versions of Vail will no longer function and Microsoft will not be releasing a patch to extend the preview period. They will however be coming out with a Beta of the latest version of Vail which will feature RAID instead of Drive Extender. If you are like me this is very sad to hear that I have to wait up to 6 weeks for my home server to be up and running again with the new beta. Goodbye Drive Extender we loved the time we had with you.
