It is always a good idea to keep your own archive of your work. Get into the habit of making a backup of your entire ePortfolio each semester. You can also use the same tool to download a digital copy of your ePortfolio for events which don't have internet access.
For some modules, you can retrieve an auto save of the content. If you delete the module all of its content disappears forever. There is no way to retrieve a deleted module, page, section, or ePortfolio unless you have made a backup of it.
Go to Portfolio Tools> Download.
Select the Download button.
Downloads can take time. As the ePortfolio loads your progress will be displayed.
Cancel to terminate the download.
