It is a good idea to create backups anytime you make changes to Ignition. You can create an Ignition backup in three different ways:

To Create a Backup in the Gateway Webpage

Go to the Configure section of the Gateway webpage.
Click on System > Backup/Restore.
The System Backup/Restore page is displayed.
Click the Download Backup button.
By default, this downloads a .gwbk file to your local file system in your Downloads folder. The Gateway backup includes everything in Gateway, that is, all projects, Ignition Tags, security profiles, global resources, database connections, OPC and Device connections, and all the Gateway settings. The only things that are not included in a Gateway backup are modules and the data stored in other programs (like databases). You can backup information stored in other software separately.

To Create a Backup using the Gateway Control Utility (GCU)

Open the Gateway control Utility (GCU).
Click on Gateway Backup to create the Gateway backup .gwbk file. Your Gateway backup will be automatically saved to your default Downloads folder (based on your web browser) unless you select another location.

Gateway Control Utility backups

You can ONLY access the GCU from the machine that the Gateway is installed on, and if you have Administrator access.
