Hello,   You would want to refer to the Admin guide for the software running on your storage to know for sure, but I do not expect that you will be able to do this. I've got a link below to the document part of the support page for the SC5020,  so that you can locate the appropriate Admin Guide more easily.   [URL]   EDIT: You might also take note of the SCOS version, so that you can make sure that there aren't any relevant callouts in the Admin Guide.
Hello! Does the SC5020 support the transfer of software backups and configuration files using SFTP or SCP?
