The Speedcube.de forum used to be a German Speedcubing forum based on the MyBB forum software.
It was archived in September of 2024 and replaced by a static read-only version.

Archiving was done by running the following wget command against the forum:

wget \
  --recursive \
  --level inf \
  --page-requisites \
  --convert-links \
  --adjust-extension \
  --restrict-file-names=windows \
  --wait 0 \
  --span-hosts --domains=forum.speedcube.de,speedcubers.de \
  --trust-server-names \
  https://forum.speedcube.de/

The above command was chosen based on these considerations:

• Don't use --mirror and instead specify --resursive and --level inf separately, because --mirror also implies --timestamping, and timestamping was not supported by the server anyway.
• Use --page-requisites, --convert-links and --adjust-extension to make the archive completely self-contained and statically servable.
• Use --restrict-file-names=windows to make the converted filenames more portable. Notably to replace the query parameters' ? with @.
• Use -wait 0 to speed up the process, since the old server did not impose any rate limits anyway.
• Use --span-hosts --domains=forum.speedcube.de,speedcubers.de to also traverse speedcubers.de, which just redirects back to forum.speedcube.de.
• Use --trust-server-names to have the speedcubers.de redirects render as their redirect target in the produced archive, so the redundant redirect hops through speedcubers.de become regular relative links in the final result.
• The --no-clobber option would have been used to be able to resume partial downloads by having wget respect and use files already existing on disk. However, this does not work as wget claims the option is incompatible with --convert-links. I was unable to get wget to resume any partial downloads and had to start over each time my hard drive got full. See also https://savannah.gnu.org/bugs/index.php?62782#comment2 for a comment of mine on the gnu issue tracker.

The command took 1 week to traverse the entire forum and download all files, and 1 more week to convert all links. The majority of the slowdown was caused by wget having to parse posts in threaded mode, which are not only many in number, but also each very large. See for example Thread #7728.

Because the produced mirror is around 260GB large, and buying a server with that much disk space just for serving it would be expensive, the final mirror was compressed into a SquashFS file instead:

mksquashfs forum.speedcube.de forum_speedcube_de_archive.sqsh -comp zstd

The file can be downloaded at forum.speedcube.de/forum_speedcube_de_archive.sqsh.

SquashFS not only supports good compression (I used zstd in this case) but also efficient random access. The resulting file only measures ~12GB can then be mounted, allowing access to the individual files again. This requires ad-hoc decompression of each accessed file, which is well worth it.

mkdir /mnt/forum_speedcube_de_archive
mount -t squashfs -o loop forum_speedcube_de_archive.sqsh /mnt/forum_speedcube_de_archive

This line was added to /etc/fstab to automatically mount the archive at boot:

/path/to/forumbackup/forum_speedcube_de_archive.sqsh /mnt/forum_speedcube_de_archive squashfs defaults 0 0

The produced static files are now served via a nginx config like this:

server {
    server_name forum.speedcube.de;

    # rewrite does not work with query params
    # so we're using ifs and returns instead.

    # Some Actions (e.g. action=lastpost) used to dynamically determine where to navigate,
    # and then navigate to an actual canonical URL, e.g. to the respective page of the newest post.
    # They don't make sense anymore since all content is static now, so remove them.
    if ($request_uri ~ ^(.*?[?&])action=(?:lastpost)&(.*)?$) {
        return 301 $1$2;
    }
    if ($request_uri ~ ^(.*?)[?&]action=(?:lastpost)$) {
        return 301 $1;
    }
    # The query parameter separator '?' was replaced by '@',
    # and all files got '.html' appended.
    # Some files, e.g. under /archive, might already have an '.html' extension.
    if ($request_uri ~ ^(.*?)\.php\?(.*?)(?:\.html)?$) {
        return 301 $1.php@$2.html;
    }
    # redirect index.php to index.php.html
    if ($request_uri ~ ^(.*?)\.php$) {
        return 301 $1.php.html;
    }

    location =/forum_speedcube_de_archive.sqsh {
        root /path/to/forumbackup/;
    }
    location / {
        root /mnt/forum_speedcube_de_archive;
        index index.html index.php.html;
    }

    # HTTP/80 works, but in reality it's HTTPS/443, auto-configured using letsencrypt's certbot
    listen 80;
}

Additionally, speedcubers.de used to be a redirect to forum.speedcubers.de. For that, see github.com/SpeedcubeDE/speedcubers-redirect.
