🎯 Backup Strategy Overview

What Gets Backed Up

Critical (Daily Full Backup):

• Source code (src/)
• Public assets (public/)
• Content files (src/content/)
• All config files (.config.mjs, .config.ts)
• Dependencies (package.json, package-lock.json)
• Environment files (.env, .env.example)
• Middleware and content config

Excluded (Not Backed Up):

• node_modules/ - Reinstallable via npm
• dist/ - Build artifacts (regenerated)
• .astro/ - Temporary build cache
• test-results/ - Test outputs
• .git/ - Version control handles this
• backups/ - No recursive backups

Retention Policy

Backup Type	Frequency	Retention	Max Count
Daily	2:00 AM	7 days	7 backups
Weekly	Sunday	4 weeks	4 backups
Monthly	1st of month	3 months	3 backups
Incremental	Every 6h	72 hours	~12 backups
Pre-deploy	On deployment	Last 10	10 backups
Safety	Before restore	30 days	Variable

Storage Requirements

• Daily: ~50-100 MB per backup = ~700 MB
• Weekly: ~100 MB × 4 = ~400 MB
• Monthly: ~100 MB × 3 = ~300 MB
• Incremental: ~20 MB × 12 = ~240 MB
• Pre-deploy: ~64 KB × 10 = ~640 KB
• Total estimated: ~1.6 GB

🚀 How to Use

Quick Start

# 1. Initial setup (one-time)
bash scripts/backup/setup.sh

# 2. Create first full backup
npm run backup:full

# 3. Verify it worked
npm run backup:verify

# 4. Set up automation (see below)

Daily Operations

# Manual backups
npm run backup:full          # Full backup
npm run backup:content       # Content only (fast)
npm run backup:config        # Config only

# Monitoring
npm run backup:verify        # Health check
npm run backup:list          # List all backups

# Recovery
npm run backup:restore       # Interactive restore

Setting Up Automation

Linux/macOS (cron):

crontab -e
# Copy templates from scripts/backup/cron.example

Windows (Task Scheduler):

# Run as Administrator
.\scripts\backup\windows-tasks.ps1

🔐 Security Considerations

Environment Variables

• .env files are backed up for disaster recovery
• Backups stored locally (not in git)
• Recommendation: Encrypt backups if storing off-site

  gpg --symmetric --cipher-algo AES256 backup.tar.gz
  

Access Control

• Backup directory excluded from git (.gitignore)
• Restrict access to backups directory (DevOps only)
• Use secure channels for off-site storage (SFTP, S3 with encryption)

Backup Integrity

• Every backup is verified after creation (tar -tzf)
• Automated verification runs daily at 9:00 AM
• Corrupted backups trigger alerts

---

🔄 Automated Schedule

Time	Task	Script	Frequency
2:00 AM	Full backup	backup-full.sh	Daily
Every 6h	Content backup	backup-content.sh	4× daily
3:00 AM Sun	Cleanup	cleanup-old.sh	Weekly
9:00 AM	Verify health	verify.sh	Daily
On deploy	Config backup	backup-config.sh	As needed

---

📋 Pre-Deployment Integration

The backup system integrates with deployment:

# Automatic config backup before deployment
npm run deploy  # Includes backup:config

# Manual pre-deployment backup
npm run backup:config

Always backed up before deployment:

• Environment variables
• Configuration files
• Middleware settings
• Content config schema

---

🆘 Recovery Procedures

Full System Restore

# 1. List available backups
npm run backup:list

# 2. Choose backup and restore
npm run backup:restore backups/daily/full-backup-2026-03-21.tar.gz

# 3. Reinstall dependencies
npm install

# 4. Rebuild
npm run build

# 5. Test
npm run test

# 6. Verify content
npm run dev

Partial Restore (Content Only)

# Extract content from backup
tar -xzf backups/daily/latest-full.tar.gz src/content/

# Verify changes
git status

# Test build
npm run build

Config Rollback

# Restore from pre-deployment backup
npm run backup:restore backups/pre-deploy/latest-config.tar.gz

# Restart service
npm run start:prod

📊 Monitoring & Alerts

Health Checks

Daily verification at 9:00 AM checks:

• ✅ Latest backup age (<24 hours)
• ✅ Backup integrity (not corrupted)
• ✅ Disk space availability
• ✅ Storage usage (<5GB)

Alert Thresholds

Condition	Severity	Action
Latest backup >24h	⚠️ Warning	Check cron/tasks
Latest backup >48h	🚨 Critical	Manual backup now
Corrupted backup	🚨 Critical	Re-run backup
Storage >80% disk	⚠️ Warning	Run cleanup
Storage >5GB total	⚠️ Warning	Review retention

---

🧰 Maintenance Tasks

Weekly

• Review backup logs: tail -100 backups/backup.log
• Check storage usage: du -sh backups/
• Verify latest backup: npm run backup:verify

Monthly

• Test restore procedure (CRITICAL)
• Review retention policy
• Clean up safety backups: npm run backup:cleanup
• Update documentation if needed

Quarterly

• Review automation schedule
• Test restoration on clean environment
• Update backup strategy if architecture changes
• Review off-site backup strategy

---

🐛 Troubleshooting

Common Issues

1. Backup script fails

# Check disk space
df -h

# Check permissions
ls -la backups/

# Make scripts executable
chmod +x scripts/backup/*.sh

2. Restore fails

# Verify backup integrity
npm run backup:verify backup-file.tar.gz

# Check contents
tar -tzf backup-file.tar.gz

3. Cron jobs not running

# Check cron service
systemctl status cron

# View cron logs
grep CRON /var/log/syslog

# Verify crontab
crontab -l

4. Windows tasks not running

# List scheduled tasks
Get-ScheduledTask | Where-Object {$_.TaskName -like 'WorkRoot-*'}

# View task history
Get-ScheduledTask -TaskName "WorkRoot-DailyBackup" | Get-ScheduledTaskInfo
