There is nothing which would not allow emacs to write a backup file in that 
directory

rd@Testing:~/local/Managed$ touch test.txt
rd@Testing:~/local/Managed$ ls -l test.txt
-rwxrwxrwx 1 root root 0 Apr 20 11:48 test.txt
rd@Testing:~/local/Managed$ rm -rf test.txt
rd@Testing:~/local/Managed$

For me the crucial message is

basic-save-buffer-2: Unlocking file: Operation not permitted, /mnt/dor1rt/Local/
Managed/sb.blog

(~/local is a symlink to /mnt/dor1rt/Local/)

What does this message exactly mean and what is emacs trying to do here? 

Other editors (vi, kate) don't report any issue when performain an edit 
operation. Is emacs trying to derive permissions in a different way?

Thanks
Rainer
