Lesson learned? Do the backups just a little more often!
As in... every hour?!
I've used it dozens of times to get stuff that I've accidentally lost or corrupted, but never for a System restore. Just let it run. Occasional running will always take longer than the one each 60 minutes, and you'll have all the stuff you created and erased since that last back up.
