osx remote backup wrong permissions

Hi All,

FWIW, I got my test to work. I realized the permissions were actually ok- the owner/group bits were off. I set up a root account on the other laptop and logged out of it then ran

/rsync -aNHAXx  --protect-args --fileflags --protect-decmpfs --force-change --stats --progress -v --rsync-path=/rsync  /private/var/audit  root at ipAddress:/Users/myUser/backup

and the resulting owner (System) and Group were preserved.

Does the server (or other computer in this case) always need a root account established for this to work? I tried everything else and the owner always became that of the remote user.

Cheers,  Rob

I copied the whole System but the results were the same though some files had permission denied errors. The output on my test folder show nothing remarkable, no errors, etc.  Am I missing something here?
