1. Years ago, like 2002

I had a similar problem. I downloaded free recovery software that allowed me to scan the unwritten parts of the hard drive bit by bit to find the lost parts. It was work, a day or so, but it was a lot larger than 2 days work, it was the whole thing. I don't recall what it's called. But don't write other things to the hard drive in the meantime. Google to search and find similar software. The lost backup is there on your hard drive.

Most people today would say, backup automatically to the cloud each night, and save to a USB stick, they're cheap enough.
