  • tl;dr Duplicity does full or incremental backups, BorgBackup only does full backups but with deduplication.

    After the first backup with Duplicity, you can choose to do an incremental backup which will only store the data that has changed since the last backup. This saves time and disk space but you have to do slow full backups regularly. See question 3 of the FAQ.

    BorgBackup alway does a full backup. But it divides all data into chunks or blocks (don’t know what they call it exactly at the moment). It then hashes those chunks and stores them in a content-addressed storage layer. So it basically works like Git under the hood (plus encryption). If a chunk doesn’t change between backups it‘s already there and does not have to be stored again. A backup is always a full index of the data.

    With today‘s fast processors and hashing algorithms, a backup with Borg should be just as fast as an incremental backup with Duplicity. If you ask me deduplicated backups are just plain superior.

    Another tool that works like BorgBackup is Restic, which I prefer. Both are good choices that I would trust with my data.










  • I hate these clickbait articles.

    • “Training GPT-3 consumed as much water as producing 370 BMWs”
    • “Bitcoin mining consumes as much electricity as Country X”
    • “One Google search consumes X amount of energy”

    Yeah, okay. So what? What am I supposed to learn from that. Is that a lot, is that a little? These kinds of articles never discuss how much or how little utility is derived

    So datacenters consume electricity and water, just like many other industrial processes. And this is interesting how exactly? They say that training GPT-3 required as much water as producing 370 BMW cars, but they don‘t discuss which


  • Your first and second points are incorrect.

    First, no your ISP cannot see anything if you are using a VPN. They only see encrypted packages and might be able to determine that you are using a VPN but they absolutely cannot tell what data you are sending or receiving.

    Second, I have never experienced that a ISP in Germany throttles torrenting, even without VPN. Torrenting per se is not illegal, you can download Linux ISOs via torrent. We still have net neutrality in the EU and in Germany. Throttling torrents would violate net neutrality and would be illegal AFAIK.
