Although I've never lost a hard drive, various things will go wrong with computers. Either the hard drive will eventually fill up, or a system board could go out, or, as happened to me last week, a power inverter board got toasted and I had to replace it. I have tried various things to keep files backed up. I'd be interested in hearing how you all out there handle this issue. Burn to CD or DVD? External drive? Online storage? Home server? I'm weighing options and could use some ideas.
