Yes, of course. That's the version I just accidentally deleted all the source code for before committing it.
Fortunately I do full system backups every day and cycle my backups through car -> closet > USB dock and I found the code in my car's glove compartment (glove box for you limey and aussie types).
People call me paranoid but it doesn't mean they're not out to get me.
I've been saved at least 5-10 times by backups over the years, both for OS and data. I cannot understand people that do not do backups. My niece doesn't bother even after I set her up with an external drive and Reflect. If her disk crashes she's going to lose 20 years of photos and other irreplaceable stuff. I guess she'll just say "Oh, well." On my last trip the external drive was gone. "Where's the drive?" "It's buried somewhere in the basement, I wanted to declutter the desk."
