rsync - Dec 2019 - How Can I save the original permissions while setting g+rX for all files

Hello list!

Combining -M--fake-super with --chmod ends up changing the permissions
stored in the fake-super xattrs. I.e. the permissions stored in the xattr, 
are
affected by --chmod.

The desirable behaviour for me would be for --chmod to modify the real
permissions of the destination files. The use case is writing a backup as a
non-root user, having it readable by the group (g+rX), while also saving 
the
original permissions in the xattr.

Is it a bug? Any suggestions on how I can achieve what I want?


Thanks in advance,
Dimitris

When I try it the chmod works on both the real permissions and the
permissions in the xatttr.  Maybe the behavior has changed since
whatever version you have (3.1.3 here) but this probably wouldn't help
you either.

Yes indeed, it is setting both the permissions. So it sets the desirable 
access rights to the file, but does not save the original mode in the 
xattr. So it's not really working out for me.
