Progress may migrate from Quest upon installation, but is not continually synced. See limits, directories and test scenarios.
Direct answer
Meta's documentation explains that Cloud Backup can restore the most recent backup from another device to Meta VR Glasses when the app is installed and there is no local backup for that device. This does not create continuous synchronization: after installation, each device maintains its own history. The backup only captures compatible directories and has a limit of 100 MB; when exceeding it, the operation fails. Teams should test automatic and manual restore with dedicated accounts, supported versions, and unique progress values before releasing the migration.
Restoration happens at installation
The system first looks for a backup of that device. Without it, you can use the latest from another device belonging to the same person.
Backup is not synchronization
After installing, changes made on two devices may differ. Products that require continuous state need their own service and conflict resolution.
Directory and size determine coverage
Data outside of compatible folders does not enter the package; above 100 MB the backup fails. Saved state inventory must be tested, not assumed.
Test account avoids real loss
The procedure may involve removing application and backup. Use disposable data, evidence of timestamps, and a unique value that proves the restored origin.
Nexus Reading
Treat continuity as a product requirement: document source, timing of restore, version compatibility, fallback, and clear message when the state cannot be recovered.
FAQ
Does Cloud Backup keep Quest and VR Glasses in sync?
No. Meta reports that the feature restores data, but each device maintains separate history after installation.
What is the limit per backup?
The documentation indicates 100 MB; above that, the backup fails.
Does the simulator validate the entire flow?
No. Meta classifies the final validation of services and backup between devices as physical testing.
