> I used to have a "poor man's time machine" system based on rsync + hard links to files that didn't change with new backups. I build something similar, that runs on a Raspberry Pi and creates backups for the machines in my home network [0]. The Pi pings each machine every hour, if a machine is online and a backup is due, it starts a backup process. My Pi uses a USB battery as a UPS (unlimited power supply) [1]. I put all the hardware in a little medicine cabinet on the wall [1]. It's been running stable for month now, without a single reboot. It needs about 15 minutes to backup my dev machine over WiFi. It's a little independent backup module, I'm really happy with it. :) [0] https://github.com/feluxe/very-hungry-pi https://github.com/feluxe/very-hungry-pi [1] https://www.amazon.de/gp/product/B00FAU7ZB2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 https://www.amazon.de/gp/product/B00FAU7ZB2/ref=oh_aui_searc...

Surely you mean Uninterruptible Power Supply. I would indeed be interested in an unlimited one myself.

  This makes sense now that you say it. Whatever it is, it powers my Pi very well :)

I similarly have a Pi in a cupboard doing the backups. In my case though, it uses wake-on-lan to wake the computers up in the middle of the night to run the backups, then lets them go back to sleep after. I use rsnapshot to a encrypted external usb disk.

I used to have a Pi for that, but the poor IO was annoying when you needed to backup large files. I got a small Atom board instead, which runs circles around it. And since it's a regular x86 board, I can use rtcwake to make it sleep between each backup, so the power consumption is quite good.
