File History is a built-in Windows backup feature designed to protect your personal files from accidental loss, damage, or deletion. Introduced in Windows 8 and available in Windows 10 and 11, it automatically creates incremental snapshots of your data and saves them to an external drive or a network location. 🛠️ Key Features
Automated & Incremental: It monitors your folders for modifications using the NTFS change journal and copies only the files that have changed since the last run.
Time-Machine Style Retention: By default, it saves snapshots hourly and keeps them forever. You can adjust the frequency (from every 10 minutes to daily) and data retention periods to preserve storage space.
Local Offline Cache: If your backup drive is disconnected, File History continues caching copies to your internal hard drive, pushing them to your external storage once it is reconnected. 📂 What It Backs Up
