Trouble moving tons of files from OS X server attached RAID to NAS I am trying to move many thousands of files to a Synology NAS.

Thanks to excellent posts here and superuser, I have been using rsync a lot. But in this case, I'm getting a very high failure rate due to years of permissions problems across the board. 

Any ideas on how I can get all these files copied, either by straightening out the permissions issues, or bypassing them? Once on the NAS, the permissions won't matter.
Assuming these are read permission issues you should be able to overcome them by running

sudo rsync …


If you don't need the various read permissions on the original files, you can also use

sudo chown -R $USER source/dir 


first to change file ownership to yourself.
