FileZilla is a free open source FTP client which you can use in Ubuntu 10.1o for backing up, or uploading your website files to and from your web server/web hosting account. It is very easy to use and reliable. Filezilla works with FTP, FTP over SSL/TLS (FTPS) and SSH File Transfer Protocol (SFTP).
I been using it for many years for uploading and backing up my files on my web server for JohnsonYip.com and other websites I own.
