I've been using Windows Live OneCare for over a year now and I really like it. Currently I'm using Windows Live OneCare to perform local backups of 3 PCs (2 running Vista and 1 running XP). The backups are going the the Windows XP box that has mirrored 500GB drives where the backups are being stored. When Windows Live OneCare expires: 1) Can I continue to use it to do my local backups? 2) Can I download the new anti-virus software and continue to use Windows Live OneCare to do local backups? 3) Will Windows Live OneCare continue to perform system cleanings and defragmentation of my HDDs?
