I had a FreeBSD box with data on a gmirror of two disks for a decade. Twice in that period I had one of the disks die. Each time I would buy a new disk, add it into the array, and go on with next to no effort. As for cost, I would have had the box anyway, so it wasn't like i was paying for an extra system, just an extra disk. Cloud backup would have cost me several orders of magnitude more, this was a media library of hundreds of gigabytes, eventually low terabytes. Plus all the complexity of working backup/restore procedures.

The average price of power during a year here is around €0.45/year, so a box drawing 50W (not unlikely with a decade old processor and two disks) will use 438 kWh during a year, meaning it would cost €197/year to keep it powered. Add to that the ~€150 x 2 for new drives, and you end up with €227/year, or €19/month. But of course, if you, as you stated, had the box running anyway, the math works out differently as you're essentially splitting the cost with whatever purpose the box already fulfills.
