I managed to pull off a lot of small stuff off the damaged drive, things like settings for certain applications (I had lost all my email server settings! But not any more).
I just scheduled backups of the databases for every day. I'll keep a week's worth of backups. I figure that's a decent amount. Those are stored on the TB drive. I may make other copies from time to time. Maybe find free online backup space and store them (encrypted, of course).
Now I'm scheduling all the backups of mail and pictures. Important stuff!
This isn't going to happen to me again, I promise you that!
