Create a tar archive using 7z compression

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.

Alternatives

There are 3 alternatives - vote for the best!

Terminal - Alternatives
tar -cJf myarchive.tar.xz /path/to/archive/

Compress files or a directory to xz format. XZ has superior and faster compression than bzip2 in most cases. XZ is superior to 7zip format because it can save file permissions and other metadata data.

tar -cvf - /path/to/tar/up | xz - > myTarArchive.tar.xz

compress directory archive with xz compression, if tar doesn't have the -J option (OSX tar doesn't have -J)

Know a better way?

If you can do better, submit your command here.

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.
