Back in august I kept hearing of people saying their upgrade from snow leopard to Lion caused them to lose much of their data on their internal harddrives. I have been hesitant to upgrade to Lion because this and I was curious has Apple fixed many of the upgrading bugs? I have a 1TB harddrive on my imac and I have no easy way of backing all this data up. Just want peoples opinions is the risk small enough to take? Can you share the story you had about your upgrade process? Thanks!
