Who are we?

We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

We are one. We are legion. And we're trying really hard not to forget.

Whenever I wipe my PC, I use tar to make an archive of the whole system. This works, but having to decompress the whole archive to pull files out is very annoying. Is there another archive format that:

  • Preserves permissions (i.e., is Unix-y)
  • Supports strong compression (I use either zstd or xz depending on how long I can be bothered to wait)
  • Supports pulling out individual files quickly

Dar

Tar = Tape ARchive

DAR = Disk Archive

It is supposed to replace tar when storing on random access media as tar isn't random access. Compression and encryption options.
