Omits the verbose option for gzip in the backup script

The verbose option dumps a progress percentage to `STDERR`. I'm piping `STDOUT` to `/dev/null` in my backup cron job but I'd like to keep `STDERR` in case something goes wrong. However because the progress gets dumped to `STDERR` by gzip it means it will always look like something went _wrong_.
