Hi xingxeon

If your shop is SMS managed and the backup is taken you can try HRECOVER with REPLACE option.
Like tso hrecover 'your data set' replace. This will replace the new version with the old. I would rather copy the new dataset to another dataset before issuing the HRECOVER to cross verify with the old version or use the NEWNAME in the HRECOVER.
