In reality, only the help desk can restore the full backup, but you can extract that full backup on your own machine and restore what ever files you need using FTP. It creates a .gz (gzipped file) so all you need is a program that can extract .gz files. When extracted it will create your directory tree as it appears on the server.
Like OJB, I backup my databases using dbsender but don't make "home" backups and instead use the "full backup" option.
