Back Up Your Computer Before Factory Reset

The mistake most people make: they assume cloud sync = backup. It doesn't. OneDrive/iCloud only sync selected folders, not programs, settings, or hidden data. A proper backup captures everything so you can restore your exact setup.

What You Need to Back Up

• Personal files: Documents, photos, videos, music
• Browser data: Bookmarks, passwords (use browser's built-in export)
• App settings: Game saves, email configs, software licenses
• Hidden locations: Desktop, Downloads, AppData folder (Windows), ~/Library (Mac)

The Right Way (Pick One Method)

Method 1: Full System Image (Easiest Recovery)

1. Connect external drive with at least 250GB free space
2. Windows: Settings → System → Storage → Advanced storage settings → Backup options → "Looking for an older backup?" → Create system image
3. Mac: Time Machine (built-in) — System Settings → General → Time Machine → turn on, select external drive
4. Let it run (1-3 hours for most systems)

Method 2: Manual File Backup (More Control)

1. Connect external drive or use cloud storage (need 50-500GB depending on file size)
2. Copy these folders manually: Documents, Desktop, Pictures, Videos, Music, Downloads
3. Export browser bookmarks: Chrome/Edge → Settings → Bookmarks → Export bookmarks
4. Check AppData (Windows: %appdata% in File Explorer) or ~/Library (Mac) for game saves/app data
5. Screenshot your desktop layout and installed programs list

Critical Pre-Reset Checklist

• Deactivate software licenses (Adobe, Office, audio plugins, etc.) — most limit concurrent installs
• Export 2FA backup codes from authenticator apps
• Note WiFi passwords if not synced to account
• Confirm backup completed: open a few random files from the backup drive

After Reset

Restore from system image (Windows Recovery or Migration Assistant on Mac), or manually copy files back and reinstall programs. Keep the backup drive for 2-3 months in case you forgot something.

Pro tip: Create a text file listing every program you use with download links. Post-reset, you'll forget half of them. Also screenshot your browser extensions and desktop layout — saves hours of "what was I using for that?" confusion.
