Spambots have gotten smarter over the years
and now they can see the various methods of hiding your e-mail
including chacter substitution and the various java scripts that try to hide the addy.
Graphic images and forms that hide the addy are all thats safe anymore.

Keep in mind that will first create a full backup on your site with the date as part of the name.
So every time you run it you add to your space.
that can add up fast.
Why not just send yourself the databases and have a home download on your computer and just update it when needed.
I do the home backup before major changes,
but I have my site on my computer normally as I use ftp to upload it.

or your computer not accepting them,

just try
/home/your-tch-cpanel-name/path-to-file/file.name
if the file is in a folder below the public_html folder, use
/home/your-tch-cpanel-name/public_html/folder-name/file.name
