Analiza zgodnie z kolejno\u015bci\u0105: odpalenie na niskim priorytecie I\/O i procesora potoku tar-uj\u0105cego do stdout. Zak\u0142adam par\u0119na\u015bcie exclud\u00f3w na katalogi i podkatalogi kt\u00f3rych nie chc\u0119 backupowa\u0107, definiuj\u0119 katalogi g\u0142\u00f3wne do backupu. wyj\u015bcie z tara kieruj\u0119 na potok wej\u015bciowy pakera 7z kt\u00f3ry dzia\u0142a z maksymaln\u0105 kompresj\u0105 i szyfrowaniem wynikowego archiwum o nazwie backup.tar.7z. U\u017cywam tara bo tar zachowuje wi\u0119cej parametr\u00f3w plik\u00f3w ni\u017ali 7z by zrobi\u0142.
Z przeprowadzonych subiektywnych test\u00f3w, 7z  pakuje z wi\u0119kszym ratio ni\u017c gzip czy bzip, chocia\u017c robi to d\u0142u\u017cej.<\/p>\n\n\n\n
