Robocopy error long path and file name too long

Dear all ,
i am facing error while making backup by robocopy .
the error as below.
the file name too long and the system cannot find the path.

Generally this issue happens when you trying to copy a file which has a path over 255 characters , and you can solve this issue by shorten the path name which should be cleared on the error message .
this if it just one path or few baths but if it is many and if you need to copy the structures as it , there is another solutions
