TAR.GZ: TAR.GZ (or TGZ) is a TAR archive compressed with gzip. It's the most common way to distribute source code and server backups on Linux.
7Z: 7Z is the 7-Zip archive format. Its LZMA2 compression usually makes files 10–40% smaller than ZIP, and it supports strong AES-256 encryption including encrypted file names.
