    The Zstd compression feature from Facebook's developers team is
    available for Tar since 1.30.90 (Git*) alpha.

    As i don't like to use alpha software on enterprise hard- and software.
    I made a simple backport-patch based on the git code.
    This allows you to use Red Hat Enterprise Linux 7's (RHEL) Tar, along with Zstd from
    Extra Packages for Enterprise Linux (EPEL).

    Ps it is always recommended to process custom APPS as RHEL Software Collections (SCL), next to the existing, not adapted APPS.

    Red Hat Enterprise Linux 7 maintained code.

    I have backported various of code lines among other things, as the testing suite is changed in Tar 1.30/alpha.

    In favor of Tar 1.26 plus patches which is used at Red Hat.

    Tested it with TB, TB and TB's of data on a medium size test farm and it works perfectly.

    Yes. As some may known. I prefer as little code changes as possible.
    Therefore this Zstd patch based on the proven Red Hat EL7, Tar 1.26.

    I only use edgie APPS with notable improvements, if I can't do it otherwise with EL7.
    Just like PHP 7+, TLS 1.3, server push, 0-RTT etc.

    Although the biggest stumbling block remains the consumer connection.
    The most degradation is stuck there, if you look at the entire chain.

    A modern site, without unreasonable concessions (to force speed above customer-experience), does not go faster than 0.3 seconds.
