Create a tar archive using 7z compression

tar cf - /path/to/data | 7z a -si archivename.tar.7z
Using 7z to create archives is OK, but when you use tar, you preserve all file-specific information such as ownership, perms, etc. If that's important to you, this is a better way to do it.

What Others Think

some newer versions of tar support the '--lzma' option LZMA is the same type of compression used by 7zip This is a cleaner option, though I suppose it is only supported by newer versions of tar which could be a problem... tar c --lzma /path/to/data > archivename.tar.lzma

According to google, GNU tar supports the lzma option since tar 1.20. Starting in tar 1.22 -J (capital 'j') means --xz and not --lzma.
