Robocopy outputs garbage percentages in log file

I am using Robocopy to back up data from a network share on a server 2008 platform to a NAS.  The copy works fine, but the log file is difficult to read.  Ideally I want to see nothing more than the job header and job summary as well as any erroneous file actions.  My command is as follows:

robocopy [source] [destination] /S /E /COPY:DT /DCOPY:T /R:1 /W:30 /NS /NC /NFL /NDL /NP  >> backup_report.txt

After reading all of the documentation on Robocopy, it reads as if /NP should eliminate the problem.  A sample of the piped log output is below:

Job Header
100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%100%
Job Summary

There are hundreds of lines of the percentage in the log.  I would appreciate any assistance in finding what I am doing wrong.

Use the /NP switch.

/NP = don' t display progress

Thank you for the prompt response.  The /NP switch is in use in my script yet the output still persists.  I realize that the percentages that appear in the log are the "completion" percentages of each file that is copied as I removed the /NDL and /NFL switches to verify.  Unfortunately the output in the log is still not what we are looking for.

I am using Server 2008 R2 that has Robocopy XP027.  I will try to run the switches one by one to see which is creating the issue.  As far as I know, the order of the switches is irrelevant isn't it?

Oddly enough the script worked last night without any edits.  It has run about 6 times now with the garbage percentages in the logs but last night it ran as scheduled and properly logged operation.  I'll go ahead and close this post and award you the points.
