I have a robocopy script to back up our Kiln repositories that runs nightly, which looks something like this:

robocopy "$liveRepoLocation" "$cloneRepoLocation" /MIR /MT /W:3 /R:100 /LOG:"$backupLogLocation\BackupKiln.txt" /NFL /NDL /NP

In the output, there are a ton of lines that contain "Extra file"s, like this:

*EXTRA File              153    E:\Kiln Backup\elasticsearch\data\elasticsearch-kiln\nodes\0\indices\kiln-2\0\index\_yxe.fdt
*EXTRA File               12    E:\Kiln Backup\elasticsearch\data\elasticsearch-kiln\nodes\0\indices\kiln-2\0\index\_yxe.fdx
*EXTRA File              128    E:\Kiln Backup\elasticsearch\data\elasticsearch-kiln\nodes\0\indices\kiln-2\0\index\_yxe.fnm
*EXTRA File              363    E:\Kiln Backup\elasticsearch\data\elasticsearch-kiln\nodes\0\indices\kiln-2\0\index\_yxe.frq
*EXTRA File               13    E:\Kiln Backup\elasticsearch\data\elasticsearch-kiln\nodes\0\indices\kiln-2\0\index\_yxe.nrm

Additionally, there are then hundreds of lines at the bottom that contain nothing but "100%"s, like this:

100%  
100%  
100%  
100%  
100%  
100%  
100%  

In addition to making the log files enormous (there are a lot of folders/files in Kiln repos), it makes it annoying to scan through the logs now and then to see if everything was working ok.

1. How do I stop "Extra Files" appearing in the log?
2. How do I stop these silly "100%" lines appearing in the log?

I've tried every combination of switch I can think of (the current switches are listed above in the command), but neither seem to hide these!
