Incremental robocopy to Netapp detects all existing files as changed or modified

Hi

We are migrating around 30 TB data from windows based file server to Netapp CIFS share by using robocopy command with /MIR switch.

After completing the baseline copy we are experiencing issues with incremental copy to Net app. Incremental robocopy to Netapp detects all existing files as changed or modified.

When i try the same command from windows as a source and another windows share as a destination, it copies only files those are changed or modified. It looks like some issue with Netapp.

Robocopy command I am using

robocopy <Windows Source>  <Netapp Destination> /mir /copyall /ZB /w:1 /r:1 /logImage may be NSFW.

robocopy <Windows Source>  <Windows Destination> /mir /copyall /ZB /w:1 /r:1 /logImage may be NSFW.

Did anyone experience same issue ?

Thanks
