You should be able to do this without JavaScript by using streaming.

Read the mysqldump man page:

       mysqldump does not dump the INFORMATION_SCHEMA database by default.  mysqldump dumps
       INFORMATION_SCHEMA only if you name it explicitly on the command line, although currently you must
       also use the --skip-lock-tables option. Before MySQL 5.5 mysqldump silently ignores
       INFORMATION_SCHEMA even if you name it explicitly on the command line.

Typo? "exists" ?

`exec` will *replace* your running script and not return to it.

What you want here, is either backticks, system, or all the way to
something like Open3.capture2 or 3.

If you want a much more elegant solution to this and other backup
things, do look at the Backup gem:

https://github.com/meskyanichi/backup

Even if you don't use it, read it and learn from it. It's quite an
elegant bit of ruby code.
