Import/Export

As the current image does not provide an efficient way to backup your projects, it is recommended to manually export your flow definition (as templates).

Go to Nifi
On the left, in the "Operate" box, click on the icon "Create Template", set a name and click on "Create"
- Now, you have a template, saved in Nifi
For exporting the template on your PC:
- In the upper right, click on the hamburger icon, then click on "Templates" in the menu
- In the list, click on the download icon to get it (it's a xml file)

For using a template:

Go to Nifi
Right click in the main page, click on "Upload template"
Select the XML file containing the template definition
Once the template has been loaded, you can add the template to your flows by clicking on the icon "Template"
