If error occurs should not copy again from the beginning

Hi..
I try to copy folders recursively..

my_dir = Dir.glob( Dir.glob("#{@source}/**/*")

my_dir.each do |f|
   File.copy(f,@@dest)
end

For example @source = e:/test_dir
If that test_dir has 10 files.if some error occurs while copying a 4th
file,Again copying of the file should not continue from 1st file to 10th
file again.
     If that 4 th file not copied due to any errors it should continue
copying from 5 th file and so on...

I think using arrray index might do the trick.
Any ideas
Thanks

my_dir.each do |f|
  begin
  FileUtils.copy(f,@@dest)
  rescue
       # some error handling
  end
end

Or

my_dir.each do |f|
  FileUtils.copy(f,@@dest) rescue nil
end

10.times do |i|
  begin
    puts "reading file #{i}"

    if i == 4
      raise "error reading file #{i}"
    end

  rescue RuntimeError => msg
    puts msg
    next
  end
end

--output:--
reading file 0
reading file 1
reading file 2
reading file 3
reading file 4
error reading file 4
reading file 5
reading file 6
reading file 7
reading file 8
reading file 9
