## ⏰ What is Time Machine?
|
|
|
|
Time Machine is macOS's built-in backup system. It automatically backs up:
|
|
- All your files and folders
|
|
- Applications
|
|
- System settings
|
|
- Emails, messages, photos
|
|
|
|
**Key feature:** You can "go back in time" and restore any version of any file.
|

## ✅ Why You Need Time Machine
|
|
|
|
| Layer | What It Protects | Frequency |
|
|
|-------|------------------|-----------|
|
|
| **Time Machine** | EVERYTHING locally | Hourly |
|
|
| **rclone + Cloud** | Critical data/configs | Daily |
|
|
| **Git + GitHub** | Code only | Per commit |
|
|
|
|
**Time Machine is your safety net if:**
|
|
- Your hard drive fails
|
|
- You accidentally delete something
|
|
- You need to restore to yesterday's version

## 📱 Step 6: For Your MacBook Pro
|
|
|
|
Since your MacBook Pro isn't always on, you have two options:
|
|
|
|
### Option A: Separate Time Machine Drive
|
|
- Keep one external drive for Mac mini (always connected)
|
|
- Keep a second external drive for MacBook Pro
|
|
- Manually connect MacBook Pro periodically (weekly)
|
|
|
|
### Option B: Network Time Machine
|
|
- Use a NAS (Network Attached Storage) like Synology
|
|
- Both Macs backup to same NAS over WiFi
|
|
- Requires initial setup but automatic thereafter
|

## 📅 Step 7: Best Practices
|
|
|
|
| Task | Frequency |
|
|
|------|-----------|

|
|
| Verify backups | Monthly |
|

|
|
|
|
## 🔧 Step 8: Troubleshooting
|
|
|
|
### "Not enough disk space"
|
|
- Time Machine automatically deletes oldest backups
|
|
- If still full: exclude large folders or upgrade drive
|
|
|
|
### "Backup delayed"
|
|
- Check if drive is properly connected
|
|
- Verify disk permissions: `diskutil verifyVolume /Volumes/DRIVE_NAME`
|
|
|
|
### "Unable to complete backup"
|
|
- First backup may fail if interrupted
|
|
- Start fresh: reformat drive and begin again
