How to backup/tar a folder and upload/ftp to another server?

The server which I have hosted my blog is not a reliable one and due to its ‘cheap’ nature it comes with no features such as backup. After a dozen of unpredicted downtime and agony, I have wrote a small bash script to use with cron jobs until I find an economic, but quality hosting. Additionally I turn off MySQL daemon so that any database read/write operation will not get ignored by tar.
