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

Take a look at DAR: http://dar.linux.free.fr/
It has many advanced functions and is actively developed (for over a decade).
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.
I use bupstash.io
