I know what I'm doing isn't typical. I'm trying to plug a hole in my backup strategy at home. Currently my music library sits on my ReadyNAS and is served around the house but isn't really backed up regularly somewhere else. I useBackblaze to backup my desktops. I recently added a machine that actually has space to hold the music. The idea is to setup a backup job on the ReadyNAS to copy the share with the music to the OS X (10.11.5) machine so that it will get backed up offsite with Backblaze. I've tried both NFS and RSync
1) I've got it all copying fine after setting up up the NFS exports file on OSX but I get the error "cp: failed to preserve ownership for `XXXX': Operation not permitted"
2) I'd be happy to switch to Rsync, but can't figure out how to set up OSX as the target for the Rsync.
Any suggestions on either fixing 1 or setting up 2?
If you look at the share settings in frontview, you will see an advanced options tab. Just click on any file protocol for the share, and you should see advanced options on the far right.
On that screen you can set the user/group, and rights for the owner/group/everyone. There's also a checkbox allowing non-owners the right to rename and delete.
Set those the way you want them, and then also check the box next to "Set ownership and permission for existing files and folders in this share to the above settings.". Then click apply on the lower right. The "set ownership" box clears immediately, and a background process runs to adjust the file owner/permissions. When it completes there will be a pop-up and a log entry.
Not sure how to reset the permissions on the ReadyNAS share? Are you suggesting doing a chown command over ssh? I'm concerned I'd lose access to the share from the other systems that access it over the network.

I think it's working now. I had to create a user on the ReadyNAS that had the same GID as the target. I also had to make sure all the files had a group ownership of a group with the same id/name that the user was a member of on the target. No more errors.
