Recently during a SAN migration, we copied data using Rysnc. Aftewards some of the users complained that the Font files where coming up as Unix Executable Files. 

This is due to the way MAC’s store font’s using resource forks and HFS meta-data. You need to copy the folder using ditto instead.

Login to Mac and Open up Terminal

*** Warning this will overwrite the folder and also subdirectories ***

Ditto –rsrc /source/folder/ / destination/folder/

You can copy this to network shares mapped in the GUI via

Ditto –rsrc /Volumes/source/folder/ /Volumes/destination/folder/

FYI As of Mac OS X 10.4, –rsrc is default behavior.
