Files stored in the “My Files” > “Downloads” folder are local and NOT backed up automatically. 

• Best Practice: Save all documents, images, and files directly into the Google Drive folder within the Files app.
• Automatic Backup: Any file placed in Google Drive is automatically synced to the cloud. 

3. Backup Before Powerwash (Manual Cloud Backup) 

If you need to perform a “Powerwash” (factory reset) or move to a new device, you must ensure local files are migrated to the cloud. 

1. Open the Files app.
2. Select all files in the “Downloads” folder.
3. Drag and drop them into the Google Drive section. 

4. Linux and Android Data:

• Linux (Crostini): If you use Linux apps, open Settings > Advanced > Developers > Linux development environment > Backup and restore. This creates a backup file that should be saved to Google Drive.
• Android Apps: Most Android app data is backed up automatically via Google Play Services, but some apps may require manual backup within the app itself. 

5. Enterprise/School Device Management:

For businesses using Chromebooks, administrators can configure policies to automatically migrate local user files to Google Drive, ensuring all data remains in the cloud. Google Help

By using Google Drive as the primary storage location and enabling Chrome Sync, you ensure that if a Powerwash is necessary, you can log in again and have your desktop, settings, and files restored immediately.
