If error occurs should not copy again from the beginning

Ruby

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
