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
I have an SSD connected to mine which doesn't need external power and runs fine off the "official" power adapter. The case I have isn't the greatest (two pieces of acrylic and some stand-offs lol), but it costed 50p and gets the job done.
As for scale, you're beyond a Pi at that point.
