If you want to read the functions file with the current shell, you'll
have to use the '.' or 'source' command (the latter being a bash
specific extension, the former the POSIX standard that works
anywhere), e.g.:

    . /backup-functions

Otherwise, the backup-functions file will be executed in a subshell
with an independent environment and so the functions defined there
won't be available in the calling script.

Also, keeping the functions in the root directory feels a bit ... icky.

To call a shell function, you don't need the brackets, so that should
be just:

    tar_backup

HTH,
