Backups & restore points · Data Backup basics
Does Data Backup back up my whole Mac?
Short answer: No. Data Backup protects the folders and files you pick, not macOS or your apps. Keep Time Machine for a full-system backup; Data Backup adds versioned copies of chosen folders on a drive or in the cloud.
No. Data Backup protects the folders and files you choose — your documents, projects, photos, and the fast drive's Storage Studio folder — rather than the whole system. It isn't a way to rebuild macOS or reinstall your apps.
For a full-system safety net, keep using Time Machine alongside it. The two work well together: Time Machine covers the Mac as a whole, and Data Backup adds versioned copies of chosen folders on another drive or in the cloud, including folders Time Machine might not reach.
