No, they are not. The Oculus Cloud backup needs to be enabled and allowed by the developers of software, applications, and games to work as a backup service on the cloud. If you’re not sure about the apps being supported by cloud backups, always make sure to go to the Oculus website, head to your profile, then to Devices and see which apps have the Cloud backup enabled for them. If you’re worried about losing data on an application that doesn’t support cloud backup, use a sideloading software like SideQuest, as I’ve recommended above.
