Yeah, I just overwrote it. I'm not gonna bother trying to recover the file. It was only 1.20 BTC and I'm not gonna sweat the small stuff.
The wallet.dat now has transactions that don't reflect the current balance, so I'm just going to delete it.
Luckily, I only had 1.20 BTC to lose, but backing up the wallet should be definitely integrated into the client.
While they're doing that, they should build in a way to "bank" your coins into encrypted files.
Well, I guess the BTCs value just got a tiny bit higher.
