Thank you for your contribution! My personal opinion is that we should keep the initialization logic out of the daily script like it was before, as this is more likely to conceal errors than help prevent them.

[mmomjian]

This is a lot more robust, thank you.

Thank you for improving the script!

if [ "$1" = init ]; then
    if _init_setup; then
        echo "init setup OK."
    else
        echo "init setup Fail, exit 1"
        exit 1
    fi
fi

Can you mention that the first time this script is run, it should be run as backup.sh init?
Or preferably, keep the section for initializing the repositories separate?

Thanks for making the changes to the script to include a helper section, looks good to me now except I got a syntax error that I commented on above. Also looks like the formatter checks are failing.
