Unfortunately this isn't a simple task. So I always recommend you print it to paper before final saving just in case the pdf printer fails. Sometimes a windows update can corrupt the pdf printer. If you have it on paper you can scan it.
If its only the most recent recon you can go to 1-3 and change the status back to open for each of the records and then re-reconcile. May not be a viable option if its a lot of records or if it wasn't the most recent recon. Same goes for bank recs.
