Sync is not backup, backup is not sync.
I had an issue - nothing new - with the backups - ouch - and this time it was my fault one hundred percent. Days ago I've bought a Raspberry Pi, just to have fun with the possibilities (media center, retro games, download center...) you can do almost everything you can imagine. One of the ideas I had was to create a usb softraid with 2 external usb drives and add the raspi as Syncthing node, because I'm using syncthing across some nodes to sync essential data, as backup (*err*).
