    Guess now not only RAM bandwidth is important, but also flash storage bw. Maybe Apple could attach more flash chips in parallel, increasing the bus width and thus the overall bandw…

    Yeah, it's a pity that TB2 cables and a TB3-TB2 adapter are still that expensive. Considering the age of that stuff, one would usually expect that to be very cheap.

    Use an (old) iMac as an external display for an Apple Silicon Mac — free, no dongle, via Thunderbolt Bridge. Apple dropped "Target Display Mode" in 2014 with the 5K iMac — and it n…

    Bugs? I don't know about any show-stoppers in borg 1.x. Design limitations? Yes, there are some, that's why borg2 will be quite different. But these are no easy or small changes. A…

    Yes, it also disallows overwriting.

    borgbackup developer here: TL;DR: don't panic, all is good. :-) Longer version: - borg 1.x style “append-only” was removed, because it heavily depended on how the 1.x storage worke…

    at first it was implemented to easily test permission restricted storages (can't easily test on all sorts of cloud storages). it was implemented for "file:" (which is also used for…

    The usual answer: "when it is ready". For low-latency storage (like file: and maybe ssh:) it already works quite nicely, but there might be a lot to do still for high-latency stora…

    no-delete disallows any kind of deleting information, that includes object deletion and object overwriting.

    borg supports the "obfuscate" pseudo compressor since 1.2.0 (since Feb 2022), that adds random extra length to the chunks, using one of 2 different algorithms to determine the extr…

    BTW, besides "cloud support" via rclone, there are also some other big changes in borg2 beta. This is the summary of the major changes (more details are in the change log): https:/…

    Basic stuff might work in a "posix-like" environment, like when using cygwin or WSL. The main problem is that there currently aren't active windows developers within the borgbackup…

    Comparisons might be interesting, but one needs to be aware that they would be a bit apples to oranges: - unreleased code that is still in heavy development (borg2, especially the …

    Thanks a lot for writing the rclone backend!

    Some people were installing / using borg on android, but guess that isn't suitable for end users, rather for the nerds. Maybe try SeedVault?

    Comment #41710626

    Please note that this is rather recent "bleeding edge" code from master branch. It is available as 2.0.0beta11, but not suitable for production yet. "Beta" also means that there wo…

    Python source code? Yes, it is on https://github.com/borgbackup/borg (if that was the question). No cloud? Indeed, borg does not integrate cloud functionality. You'll either need a…

    Besides vorta (which offers a lot of options) there is also pika backup (which might be simpler by offering less options).

    Not much. rsnapshot is based on rsync and hardlinks. So, you'll get some whole-file deduplication for unmodified files. No compression, no encryption/authentication, no way to veri…

    You could have just used the self-contained borg binary (download from github releases page). It contains everything needed (python, python libs, other libs) except glibc and relat…

    deduplicating backup tools use a symmetric approach: all archives needing some chunk (piece of data) reference it via its chunkid (the keyed hash over the chunk plaintext content).…

    I see quite some full backups in your near future. ;-) And that is one of the main reasons why chunk-deduplicating backup tools (like borg, restic, ...) are better than full/increm…
