Well it is certainly meant to, but I have always used it with the
--no-acls option. If you don't use this option, it should save
acls, and I presume it does...

Just note (from http://www.nongnu.org/rdiff-backup/features.html):

ACL and EA support: If rdiff-backup can find the pylibacl and pyxattr (mac
version) modules, and if the file system supports these features, rdiff-backup
will preserve Access Control Lists and user-level Extended Attributes. ACLs are
not supported, however, on Mac OS X or Windows as those systems do not use
standard POSIX.1e access controls.

ACLs and extended attributes are stored in separate metadata files in the
rdiff-backup-data directory and do not depend on the underlying file system
for the mirror having support for those attributes. You can delete those
attributes from the mirror, and they will still be restored correctly based
on the metadata files.  _Restoring_ a file with ACLs or extended attributes
of course depends on the destination file system supporting them.

                Do NOT delete it.
