I don't know how radosgw objects are stored, but have you considered a 
lower level rados export/import ?

IMPORT AND EXPORT
    import [options] <local-directory> <rados-pool>
        Upload <local-directory> to <rados-pool>
    export [options] rados-pool> <local-directory>
        Download <rados-pool> to <local-directory>
    options:
        -f / --force                 Copy everything, even if it hasn't 
changed.
        -d / --delete-after          After synchronizing, delete 
unreferenced
                                     files or objects from the target bucket
                                     or directory.
        --workers                    Number of worker threads to spawn
                                     (default 5)
