BorgBackup (short: Borg) is a deduplicating backup program. Optionally, it supports compression and authenticated encryption.

The main goal of Borg is to provide an efficient and secure way to backup data. The data deduplication technique used makes Borg suitable for daily backups since only changes are stored. The authenticated encryption technique makes it suitable for backups to not fully trusted targets.

Borg is a fork of Attic and is maintained by "The Borg collective".

  • Since the SlackBuild file only calls for the slack-desc, borgbackup-1.1.x.tar.gz, and the unicode_docs.patch file, I've removed the borgbackup.info file since it was out of date anyway.
  • https://github.com/dmacias72/unRAID-NerdPack/issues/34 we found in Borgbackup-1.1.14 that due to Python 3.9 being supported, llfuse-1.3.8 was supported. It needs to be installed for Borg mounting to function. I do not think it is needed for package compilation/creation, though if needed it can be grabbed from elsewhere in this repo.
  • https://github.com/borgbackup/borg/issues/5591 we found in BorgBackup-1.1.15 that xxHash-0.8.0 is now preferred as the hash library instead of a built-in hash library. That means it depends on files not installed as part of the BorgBackup package installation. During compilation of BorgBackup, it checks a Boolean https://github.com/borgbackup/borg/blob/1.1.15/setup.py#L26 and also looks for installed copies of xxHash (and its library libxxhash) to determine if this "better" library should be used or if the bundled hash library should be used. If
  • This same "check the system if this package is installed, otherwise use the bundled version" applies to lz4, libstd, and libb2 (blake2). It should be noted that if BorgBackup is compiled while the system library is used but the compiled package is then moved to a system such as Unraid without that installed package, an error such as libxxhash.so.0: cannot open shared object file: No such file or directory may be seen. This particular error was seen when running borg --version on a system without the xxhash library installed. I downloaded the library from a Slackware source mirror: http://slackware.cs.utah.edu/pub/slackware/slackware64-current/slackware64/l/
  • I updated the SlackBuild to adjust these flags in the setup.py file to False (default is True) to force usage of the bundled libraries for maximum portability between Slackware and the super-cut-down Unraid flavor of Slackware. This way, Unraid users of this package need not install extra packages such as xxHash to get BorgBackup working.
  • There were some other files in this SlackBuild directory such as acl-2.2.53, cryptography-2.8, libffi-3.2.1, lz4-1.9.2, and msgpack-python-0.6.2. I found that msgpack-python and cryptography were not installed on my build system, but when I compiled the package I did have libffi-3.3, acl-2.2.53, and lz4-1.9.3 installed. They were installed by default with Slackware, and if needed can be downloaded from http://slackware.cs.utah.edu/pub/slackware/slackware64-current/slackware64/l/.
  • I confirmed that Unraid did NOT have libffi, lz4, acl, cryptography, xxHash or msgpack installed by default.
  • The original README noted that, in order for documentation to be generated, both Sphinx and sphinx_rtd_theme needed to be installed. However, during compilation I ran into an error No module named 'guzzle_sphinx_theme' and then also needed to install https://pypi.org/project/guzzle_sphinx_theme/ with pip3 install guzzle_sphinx_theme. After that, I was able to complete the compilation.
