Thanks for your guidance Jesper. We are not Siemens programmers here and our familiarity with Step 7 revolves solely around setting up the MPI connection and "Upload station to PG". It looks as though the hardware and connections configurations are being uploaded, so that makes us feel better about the completeness of our backups. Maybe someone can verify from the screenshots below if the hardware and connections look like they are being uploaded. My novice eye's say they are but what do I know. We also occasionally get these errors. However it does not seem to hinder the upload any. All block comparisons pass just fine.

Thanks Jesper. We do have plenty of CPU to CPU comms. Do you know if there is a way I could verify that the connections are or are not being uploaded?

Hello all. Is it possible to perform a backup on the S7-300 series controllers that will allow a customer to fully recover on his own in case of a hardware failure? I myself am the customer and we routinely perform backups on all of our mission critical plc's. We have recently been told by a vendor that the backups we perform will not do us any good in the event of a hardware failure. They mentioned that the configuration tables will be missing. So I ask you fine folks. Is there anyway to perform a full backup that will get us back up and running if we have to change out some hardware? If it is not possible, what exactly can not pulled pulled out of the plc and why?
