Your backup folder MIGHT be visible to the public -- WPerror

I got this message on my WordPress blog and don't understand how to fix it.

Your backup folder MIGHT be visible to the public
To correct this issue, move the .htaccess file from wp-content/plugins/wp-dbmanager to /hsphere/local/home/user/domainname/wp-content/backup-db

Reason:
````````````
Caused due to the new Plugin Installation. i.e, WP Database backup Plugin. The issue was due to the DB Backup plugin. It tries to backup .htaccess file in the root folder and as it is missing it showed the error.

FIX:
``````
Copy the main .htaccess file of the WordPress and paste it in the folder /wp-content/backup-db under the root. It will fix the Error :D .
