    You really should demonstrate that have spent at least 30 seconds trying
    to help yourself by using a search engine.

    Linux Journal reviewed compression tools in issue 137:
    http://www.linuxjournal.com/article/8051, which would probably be
    helpful to you. It seems to require a login, not sure if that is free
    or not.

    Data recovery mode implies redundancy, which would be orthogonal to
    higest compression ratios. rar it he only one that comes to mind, but I
    am sure there are others.

    How is multi-volume support different than splitting?

    An integrated tool like that would go against the unix philosophy of
    separating concerns. It limits your options. The two standard tools to
    create archives are cpio and tar.

    Again, you would use an external tool (gpg) for that. You now need to
    decide if you want to sign the whole archive, or each volume. Make
    sure you encrypt after you compress.

    > - (optional) Password protected

    zip supports passwords on archives, and if I recall correctly they were
    trivial to break. You are better off with gpg, but it will take a
    while. If you just need integrity check use sha1 (or md5) sums instead.

    Start by reviewing this list then:
    `apt-cache search archive | egrep -v ^lib`
