Ich archiviere immer mal wieder größere Dateimengen in Archiven, nutze dafür #7zip (mit #LZMA2 und Ultra-Compression). Mit der Option "qs" und einer Dictionary Size von 1024MB werden die Archive - je nach Dateien - nochmal erheblich kleiner.
Unübertroffen ist aber #ZPAQ (dank Dedup-Algorithmus) - unglaublich, wie klein die Archive werden (Compression UND Decompression sind aber CPU- und zeitintensiv). ZPAQ hat per se keine GUI, ist aber in #PeaZIP integriert.

Any #compression experts here?

I compressed an archive of nearly identical files (snapshots of the list of my tabs) in two ways.

First, as .tar.zstd, and that gave me 325MiB.

Then, I used #7zip with #lzma2, and got only 35MiB. Much closer to what I expected.

What gives? Is #tar stringing files together in a way that prevents #zstd from detecting duplicate data across files?
