4.9.7 Backups and data backups
Regular backups or data backups after successful installation should be part of a successful
security concept. Whether for restoring a project if required, if the changes made do not yield
the desired results, or for saving an installation in an emergency.
Options for backing up STEP 7 project:
• Project backup via online backup, see article Online backup
(https://support.industry.siemens.com/cs/us/en/view/109759862/91508694411)
• Project backup via the TIA Portal, see article What options are there in STEP 7 (TIA Portal)
for backing up projects and what is the significance of the backup files of the projects?
