robocopy

Question

I been using robcopy for years and as of late its seems to be broken on my win7 32bit os 

I simply try to mirror a folder and it seems to  want to copy all the files over again 

I first   run it with the  /copy:t option  then  with the /mir option and it just copies the new files 

added to the source folder to the target 

Is there a way to debug this? 

thanks

Answer 1

Hello -- thanks for the info, but the /FFT option did make a differnece ---

What difference did it make?

umm ... since  robocopy deemed that the files  were different the source files  would be

(unnecessary) copied to the target -- 

This is what you already reported in your original post. I wanted to know that changed when you used the /FFT option.

Where did the time stamps (e.g. 130477653980000000) come from?

This is problematic  if the file trees in questions has thousands of files or very large files

my music folder is 300G and has 30K files --

Here is a small snaphot of the issue --

These 3 files show the issue -- as noted there is a source and target file --

they are the same file.  The digits before the filename(s) is the timestamps,

modify, create and access times.  The only time that differs is the access time.

When I try to clone these files with /MIR option and using the /L option to see

what would happen, robocopy copies the source to the target, and does not state

one of that tags like "newer" or "new file", "changed" ...etc

The 3 files are now copied with the time stamps so that all 3 time stamps are the same

I am not sure if this could be an issue, but I think that fix KB2639043 has been

applies to my system which could be causing this issue

Answer 5

This command should suffice:

robocopy d:\Documents G:\Documents /mir /FFT

To see all robocopy switches, run this command:

robocopy /? > robocopy.txt
