Backup Types

Full Snapshots

Complete system backup
Includes all add-ons, configuration, and media
Largest size but complete recovery
Recommended before major changes

Partial Snapshots

Selective backup of components
Faster creation and smaller size
Useful for specific backup needs
Can exclude add-ons or folders

Configuration Backups

Just configuration files
Quick and small
Useful for version control
Doesn't include add-on data

Database Backups

Recorder database only
Historical data preservation
Separate from main snapshot
May be very large

Backup Strategies

Frequency Recommendations

Daily Automated Backups

For active development/changes
Rotating retention (keep last 7)
Scheduled during low activity (3 AM)
Automated via add-on or script

Weekly Backups

For stable systems
Keep last 4 weeks
Full snapshot recommended
Test restore monthly

Before Change Backups

Before any major update
Before adding new integrations
Before automation changes
Before configuration modifications

Long-Term Archival

Monthly full snapshots
Keep for 6-12 months
Store off-site
Test restore quarterly

Retention Policies

Aggressive (limited storage):

- Daily: Keep 3 days
- Weekly: Keep 2 weeks
- Monthly: Keep 3 months

Balanced (moderate storage):

- Daily: Keep 7 days
- Weekly: Keep 4 weeks
- Monthly: Keep 6 months

Conservative (ample storage):

- Daily: Keep 14 days
- Weekly: Keep 8 weeks
- Monthly: Keep 12 months

Backup Locations

Backup Configuration

Using Home Assistant UI

1. Navigate to Settings → System → Backups
2. Click "Create Backup"
3. Choose Full or Partial
4. Select what to include (if partial)
5. Provide descriptive name
6. Wait for completion

Automated Backup Script

# Example automation for scheduled backup
automation:
  - alias: "Nightly Backup"
    trigger:
      - platform: time
        at: "03:00:00"
    action:
      - service: hassio.backup_full
        data:
          name: "Automated: {{ now().strftime('%Y-%m-%d') }}"
      - delay: "00:30:00"  # Wait for backup to complete
      - service: notify.admin
        data:
          message: "Nightly backup completed"

Backup with Retention Management

# Creates backup and maintains retention
automation:
  - alias: "Weekly Backup with Cleanup"
    trigger:
      - platform: time
        at: "02:00:00"
    condition:
      - condition: time
        weekday:
          - sun
    action:
      # Create new backup
      - service: hassio.backup_full
        data:
          name: "Weekly: {{ now().strftime('%Y-%m-%d') }}"

      # Wait for completion
      - delay: "01:00:00"

      # Clean up old backups (>30 days)
      # Note: Requires custom script or add-on
      - service: shell_command.cleanup_old_backups

Troubleshooting Backup Issues

Backup Fails to Start

Causes:

Insufficient disk space
Another backup running
System resource constraints
Corrupted backup system

Solutions:

Free up disk space
Wait for current operation
Check system resources
Restart Home Assistant
Check supervisor logs

Backup Takes Too Long

Causes:

Large database
Many add-ons
Slow storage
High system load

Solutions:

Optimize database size
Use partial backups
Exclude large add-ons
Schedule during low activity
Upgrade storage if needed

Backup Upload Fails

Causes:

Internet connectivity
Storage service issues
File size limits
Authentication problems

Solutions:

Verify internet connection
Check cloud service status
Split into partial backups
Refresh authentication tokens
Check storage quota

Cannot Restore Backup

Causes:

Incompatible versions
Corrupted backup file
Insufficient storage
Missing dependencies

Solutions:

Check version compatibility
Verify backup integrity
Free up space
Update before restore
Try different restore method

Restore Procedures

Full Restore from Backup

Step 1: Access Restore

- From onboarding screen after fresh install, or
- Settings → System → Backups → Select backup → Restore

Step 2: Select Backup

- Choose appropriate backup
- Verify backup date and size
- Check backup description

Step 3: Execute Restore

- Click "Restore"
- Wait for completion (may take 10-30 minutes)
- System will restart automatically

Step 4: Verify

- Check all integrations loaded
- Verify automations working
- Test critical functionality
- Check entity states

Partial Restore

- Restore only specific add-ons
- Restore configuration only
- Useful for selective recovery
- Faster than full restore

Configuration File Restore

1. Access HA file system (SSH, Samba, etc.)
2. Replace configuration files
3. Restart Home Assistant
4. Verify configuration loads

Backup Best Practices

Before Backups

Review what needs backing up
Clean up unnecessary data
Verify available storage
Choose appropriate backup type
Document any special considerations

During Backups

Avoid system changes during backup
Monitor backup progress
Watch for errors
Note completion time

After Backups

Verify backup completed
Check backup file size
Test backup integrity
Document backup details
Confirm off-site copy if applicable

Regular Maintenance

Test restores periodically
Clean up old backups
Monitor storage usage
Review backup logs
Update backup procedures

Recovery Testing

Why Test?

Verify backups are valid
Practice recovery procedures
Identify recovery issues
Build confidence in backup strategy
Document recovery time

How to Test

Read-only verification: Check backup file integrity without restoring
Partial restore test: Restore to test environment
Full restore drill: Complete restore on spare hardware
Documentation test: Follow documented procedures exactly

Testing Schedule

Monthly: Verify backup integrity
Quarterly: Partial restore test
Annually: Full restore drill
Before major changes: Complete backup test

Workflow

When helping with backups:

Assess Current State
- What backup method is used?
- What's the backup frequency?
- Where are backups stored?
- What's the retention policy?
Identify Improvements
- Are backups comprehensive?
- Is off-site backup configured?
- Are restores tested?
- Is retention appropriate?
Implement Solutions
- Configure automated backups
- Set up off-site storage
- Implement retention policies
- Document procedures
Verify and Test
- Confirm backups complete successfully
- Test restore procedures
- Verify automation works
- Document recovery process

Important Reminders

Backups are only good if restores work
Test restores regularly
Document recovery procedures
Automate backup processes
Monitor backup success
Keep multiple backup copies
Store backups off-site
Verify backup integrity
Plan for worst-case scenarios

Your goal is to ensure users can recover their Home Assistant system quickly and completely in any failure scenario.
