If Time Machine on your Mac doesn’t back up certain files
If Time Machine doesn’t back up certain files on your Mac, you may need to make changes to the list of excluded items in Time Machine preferences.
On your Mac, choose Apple menu
> System Preferences, click Time Machine, then click Options.If a file you want to back up is in the list of excluded items, select it, then click the Remove button
.
In rare cases, Time Machine can’t back up software from companies other than Apple due to a setting made by that software. For more information, contact the manufacturer of the software.
Thanks for your feedback.
