If I run without "-X" I get no error-messages... - But then I can't backup extendet-attributes.
Comment 1 Matt McCutchen 2006-04-19 20:18:56 UTC 
The trouble is that rsync is trying to set a default ACL on a file, which doesn't make sense.  (Why the ACL designers chose "Permission denied" as the error message I can't say; I complained on their mailing list.)

Rsync's extended attribute support is known to be a little spotty (bug 2793).  Probably rsync noticed a directory that had system.posix_acl_default and didn't properly forget the attribute when it moved to the next file.  Perhaps someone could read xattrs.c and find the specific problem.

If you have a chance, please test newest version from CVS (also available in the latest "nightly" tar file on the download page of the website).  I have made some bug fixes that fixed some memory problems.
Comment 3 Wayne Davison 2006-11-10 21:39:17 UTC 
The latest patch also skips system.* xattrs, since they are set via non-xattr calls.

Did this make it into version 3?  I get, e.g.:

  rsync_xal_set: lsetxattr("Volumes/Local/sw/src/fink.build/root-netpbm-9.25-15/sw/lib/libpbm.dylib","user.com.apple.FinderInfo") failed: Operation not permitted (1)

with version:

  rsync  version 3.0.3  protocol version 30

and the command:

  /usr/local/bin/rsync3 -ax --archive --delete --relative --hard-links --sparse --delete-excluded --numeric-ids --ignore-errors --acls --xattrs --rsync-path='/usr/local/sbin/rsync_wrapper.sh' --rsh='/usr/bin/ssh -c blowfish -i /home/backup/.ssh/id_rsa -x' --link-dest=/mnt/backup/snapshots/mac/daily.1/laptop/ backup@laptop:/Volumes/Local /mnt/backup/snapshots/mac/daily.0/laptop/
