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.
