I would use a simpler solution than those presented so far: use system() with a scalar argument and simply quote the path containing a space so that the shell sees it as a single argument.

system("mysqldump --add-drop-table -uroot -ppassword mydatabase | gzip -9c > '/home/username/Ubuntu One/mydatabase.sql.gz'");
