As a geek, I always imagine worst-case scenarios. I was worried about my data I had at home. My laptop is backuped on my server, which hosts some other websites (this wiki), and family stuff (photos, mainly).
At first, I had an external hard drive that I would connect once every blue moon (I tried at least every two months), and I would then launch a bash script that would backup the server drives into the external HDD. That was great, but I needed two things:
The backups must be automated. As we say, if something is not automated, you’ll end up not doing it.
Some physical security; what if someone broke into my house ?
The first point was easy, but if I left the HDD plugged in, if someone broke into my server, they just had to
rm -rf /
to delete the backup; no good..
For the second point, sure, the server is screwed in the rack, but maybe that makes-it more valuable ? And what about floods, the house catching fire or EMPs (wink 😉 ) ?
The first thought would be to assemble a simple computer, put an HDD inside it, an ask a friend to host it for me. But that’s a bit dumb: for a backup box, you don’t need very much “responsiveness” nor computing power: I don’t want to waste energy for nothing.
So then I thought about using a Raspberry Pi: they’re cheap, low power and noise-free. The final idea was to use an old 1U-rack case I had lying around: it’ll be nicer, sturdier and “geekier” 😉
