    What's the state of the art in archive formats?

    Hi all – What's the state of the art in archive formats, or combined archive+compression formats? Is 7z considered the best? (Does Zstd have archive features?) Did Bulat have one?

    It seems like there hasn't been much movement from TAR files, because I see people slinging them around constantly. I'm vaguely aware of RAR but I don't know much about it.

    I stumbled on this article by some dude named Antonio Diaz, arguing that XZ is inadequate for long-term archival. I haven't finished it yet, but it got me thinking about specifying a super safe archival and compression format for long-term data archival. Most of these formats seem largely undocumented, which is strange. It would be nice to have a combined format so that it takes only one step to both archive and compress.

    What makes for a good archival format? What features or philosophy?

    Thanks.

    today, 7z and arc are the best archive formats available. read https://github.com/Bulat-Ziganshin/FA to learn how they can be improved

    My favorite: Local damage to the data should not destroy all or most of it. This is one reason why tar.gz is not a great archive.
