Windows Backup Options Explained
Windows offers file history, cloud sync and system images.
File backup
Use the built-in backup features to copy documents and folders to an external drive or cloud storage.
Cloud sync
Folder sync keeps files available across devices, but sync is not a true backup because deletions sync too.
System image
Creates a snapshot of the whole system for restoring after a failure.
Recommendation
Combine regular file backup to an external drive with an encrypted cloud copy.
Key takeaway: Sync is not backup. Keep a separate copy that does not follow deletions.
