Classic power failure and raspberry pi with SD cards. When I last set up things for my parents, I simply imaged a bunch of SD cards and had the data stored on an external hard drive. I live in the US and they live in India and this is for their RaspBMC. With the SD cards they just swap a broken one with a new one and call it a day.

Been 12 years or so now. Went back to their home a few years ago and everything but the opensubtitles integration works. I was surprised. I could never recreate it now. Even has one of these flirc setups so the remote works.

India has unreliable power too so the SD card death was inevitable. I made a few more images and called it a day.
