I've got a 3 year old PC I use for development. Its been fine, but is beginning to show some problems. I've not synced any folders with SkyDrive, because I'm very concerned what happen if I loose my HD or the PC suddenly and fatally crashes. Will I loose all of the files and folders in a synced folder from SkyDrive? The folder I want to sync will have vital documentation in it, which I can't loose, so I don't want SkyDrive thinking that just because the HD may disappear on me, it should then blow it away out of my SkyDrive.
