ourFile.CopyTo("@c:\boost.bak");

because in above line you have @ inside of "..."
it should be:
ourFile.CopyTo(@"c:\boost.bak");

Even when I make this correction I still get the same error.  I have verified that the original file DOES exist on drive c:.

Also say if boost.bak already Exists in given location you may want to overrite it then you should use overload method like below:
 ourFile.CopyTo(@"c:\boost.bak",true);

I think sami has this covered, but just to re-iterate, either of these will work:

        FileInfo ourFile = new FileInfo(@"c:\boost.ini");
        ourFile.CopyTo(@"c:\boost.bak",true);

OR

        FileInfo ourFile = new FileInfo(@"c:\boost.ini");
        if (File.Exists(@"c:\boost.bak"))
        {
            FileInfo bakFile = new FileInfo(@"c:\boost.bak");
            bakFile.Delete();
        }
        ourFile.CopyTo(@"c:\boost.bak");


Only way that doesn't work is if boost.ini doesn't exist in that location, or the user (.NET) doesn't have access permissions for it.
