    There are actually really good free backup solutions, like https://kopia.io/. - Source: Hacker News / 3 months ago
  • Backblaze has stopped backing up your data
    Backblaze's B2 storage is fine if used with a separate app over which you have more control. Others here have mentioned Arq. I have used it, as well as Kopia[0] and Blinkdisk[1] (Blinkdisk is essentially Kopia but with a nicer UI). Can recommend all three highly; the latter two are FOSS.

  • Archival Storage
    Regarding the first two points, maybe Kopia [0] come close. It has both GUI and a CLI. For the GUI, it saves your backup key for you (although I have to admit I didn't check how much securely stored it is), but you still have to keep a copy yourself in a password manager or similar in case you need to access your backup from some other machine. AFAIK, for the CLI you are completely on your own regarding secrets... - Source: Hacker News / over 1 year ago

    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
