I am trying to set up mirroring with robocopy to backup directories to micro-sd cards, as:
ROBOCOPY "C:\test" "E:\test" /MIR /COPY:DT /Z /W:5
This works fine for the most part except for PDF files for some reason, halting the process and returning the error:
2019/05/24 16:13:41 ERROR 87 (0x00000057) Changing File Attributes C:\test\test.pdf The parameter is incorrect.
Copying manually is not issue, both volumes (C: NTFS, and E: exFAT have been checked to be ok) and I have tried to circumvent it with all kinds of flags with not resolution. Does anyone have any ideas what the issue could be?
