Tonight has been the first night I ever used Time Machine. I've had it setup since getting Leopard last year but have never needed to use it. I actually briefly considered last week turning it off so I could use my external for some other files, but decided I'd keep it going just in case - "you never know..." So anyway, this evening I was cleaning up and deleting some of my files and emptied my trash to free up some space on my main drive. I went to eat dinner, watch some TV, have a shower, and came back a few hours later and noticed a folder on my desktop was missing. This folder contained all the work I had done today - nearly 2gigs of Photoshop and InDesign files. Panic set in for a few seconds before I remembered Time Machine. So I fired it up, found the folder I needed (Time Machine says I deleted it about 5 hours ago which seems right), hit restore, and 6 seconds later it's back on my desktop safe and sound. Thank you Time Machine!
