The best way to backup Windows 10 to external drive?

The best backup strategy for Windows 10 combines multiple methods to ensure comprehensive data protection.

Start with File History, a built-in tool that automatically backs up personal files (documents, photos, etc.) to an external drive or network location. Enable File History in Settings > Update & Security > Backup, and set it to run hourly or daily. This ensures frequent, incremental backups of your most important files, allowing easy recovery of previous versions if needed. Pair this with OneDrive or another cloud service for offsite backup, protecting your data from physical damage or theft.

Second, practice the 3-2-1 rule: keep 3 copies of your data (primary + 2 backups), on 2 different media (e.g., external drive + cloud), with 1 offsite (e.g., cloud or a remote drive). Regularly test your backups by restoring files or system images to ensure they work.

Combine automated tools with manual checks for a robust strategy that minimizes downtime and data loss. This layered approach ensures you're prepared for hardware failures, ransomware, or accidental deletions.
