Backup Features of Mac OneNote

Click on the "Backup" feature. Enter the backup page. There are buttons and checkbox options.

Backup Folder

“Open Backup Folder” button: Because the OneNote backup folder is very deep, this button quickly and easily opens the folder directly and quickly with the Mac Finder.


Specifies the interval between automatically backing up notebooks. The default is to take a backup every week.

Open Backup Folder

Click on the "Open Backup Folder" button. You can jump to the backup folder of OneNote:
/Users/james/Library/Containers/ Support/Microsoft User Data/OneNote/15.0/Backup
Here we can see that there is a Backup folder. Inside is our notebooks.
Similar to the Backup folder in Windows OneNote. The storage inside is to store each section group and section by notebook folder.
  • A notebook is a folder
  • A section group is a subfolder
  • A section is a .one file (although this file has parentheses and date)

Open Backups Feature

With the .one file, you can do the restore operation.
In the Mac OneNote main menu - > File menu - > “Open Backups” menu item.

Open Backups Feature

Choose a .one File from the Backup

In fact, the "Open Backups" menu item is also open "Open Window".
At the bottom of the Recent Folders list, in Other Locations, there is the Backups folder for your local computer.
Click on the "Backups" folder, and the right side of it will list the notebooks (folders) backed up in the backup folder.
Click a notebook folder and the .one files of the sections is listed to the right.
Select a .one file and the Open button at the bottom of the window will light up.

The Restored Section .one File Opens as Read-only and is Listed in the Temporary Open Sections Notebook

When you click the Open button, OneNote opens the section, but with some differences:
  1. OneNote opens the backup section as read-only.
  2. This section is listed in the temporary "Open Section" notebook.

How to Handle Read-only Section?

Read-only section that you cannot modify. You can only move the section to an ongoing notebook by right-clicking on the section and using the "Copy or Move" function in the right-click menu.
This makes the section available.
