I use robocopy on my windows XP. I have noticed a problem with it. I am wondering if you have experienced the same and have a workaround for it.

If I have already taken a backup using robocopy, and then change the security descriptor or attributes (read only, hidden etc) on a file in the source directory, taking a backup again using robocopy does not copy the new security descriptor or attributes to the backed up file. However, if I write something to the file in the source directory and then take a backup using robocopy, the changed security descriptor, attributes get copied on the backed up file. This seems to work fine for subdirectories. It’s only a problem with files.

I use the following command string:
C:\Program Files\Windows Resource Kits\Tools>robocopy src_dir
dst_dir *.* /COPY:DATSOU /E /B /MIR

Do you have any idea how to fix this?
