    tar.tgz files that are already tar'ed and gzip'ed

    Folks:

    Will compress tarballing an already compressed tarball cause issues or file corruption?

    I do backups that tar and gzip files and directories into remote locations; however, I noticed that I already have software releases already tar'ed up. Examples:

    'release-1_03_04.tgz'
    'release-1_03_05.tgz'

    Then I have my weekly archives as '20130712.tgz'; however, my 'release.tgz' files are included in the weekly backup.


    Thank you
    Arrakis

    I don't know with 100% certainty, but I'm pretty sure it's OK. I've tarballed directories containing files and other tarballs before and never noticed a problem extracting the data later on.

    No, it won't cause any issues.
