@tonyshowoff said in Linux: Zip and 7Zip: Sorry if this was mentioned but I didn't see it directly mentioned for clarity: If your compression is unavailable directly in tar (-J being essentially 7zip, my favourite), you can tar it first (without compression) and then compress the tar, this maintains both Unix metadata and also gives the benefit. Also, if you compress something already compressed you won't get the best benefit, at least not when it comes to using something as powerful as LZMA/7zip. I believe that that is mentioned in the tar article.
