Backup and Restore Guide

Complete guide for backing up and restoring the AI Store application.

Backup Strategy

What to Backup

1. Code: Git repository
2. Database: Database dumps (if applicable)
3. Files: User uploads, static files
4. Configuration: Environment variables, config files
5. Secrets: API keys, certificates (securely)

Code Backup

Git Repository

Primary Backup: Git repository (GitHub/GitLab)

# Push to remote
git push origin main

# Create backup branch
git checkout -b backup/$(date +%Y%m%d)
git push origin backup/$(date +%Y%m%d)

Local Backup

# Create archive
tar -czf backup-$(date +%Y%m%d).tar.gz \
  --exclude=node_modules \
  --exclude=.next \
  .

Database Backup

Automated Backups

# PostgreSQL example
pg_dump -U username database_name > backup-$(date +%Y%m%d).sql

# MySQL example
mysqldump -u username database_name > backup-$(date +%Y%m%d).sql

Backup Schedule

• Daily: Full backup
• Hourly: Incremental backup (if applicable)
• Weekly: Archive old backups

File Backup

User Uploads

# Backup uploads directory
tar -czf uploads-backup-$(date +%Y%m%d).tar.gz public/uploads/

Static Files

# Backup public directory
tar -czf public-backup-$(date +%Y%m%d).tar.gz public/

Configuration Backup

Environment Variables

# Backup .env files (securely)
# Store in secure location
# Encrypt sensitive data

Configuration Files

# Backup config files
cp next.config.ts backup/
cp package.json backup/

Backup Storage

Storage Locations

1. Primary: Cloud storage (S3, Google Cloud)
2. Secondary: Local storage
3. Tertiary: Offsite backup

Backup Retention

• Daily: Keep 30 days
• Weekly: Keep 12 weeks
• Monthly: Keep 12 months
• Yearly: Keep indefinitely

Restore Procedures

Code Restore

# From Git
git clone <repository-url>
cd Server-December-AIStore
npm install

# From backup archive
tar -xzf backup-YYYYMMDD.tar.gz
cd Server-December-AIStore
npm install

Database Restore

# PostgreSQL
psql -U username database_name < backup-YYYYMMDD.sql

# MySQL
mysql -u username database_name < backup-YYYYMMDD.sql

File Restore

# Restore uploads
tar -xzf uploads-backup-YYYYMMDD.tar.gz

# Restore public files
tar -xzf public-backup-YYYYMMDD.tar.gz

Disaster Recovery

Recovery Plan

1. Assess Damage: Determine what was lost
2. Restore Code: Restore from Git or backup
3. Restore Database: Restore from database backup
4. Restore Files: Restore user uploads and files
5. Verify: Test application functionality
6. Document: Document recovery process

Recovery Time Objectives (RTO)

• Critical: < 1 hour
• High: < 4 hours
• Medium: < 24 hours
• Low: < 72 hours

Recovery Point Objectives (RPO)

• Critical: < 15 minutes
• High: < 1 hour
• Medium: < 24 hours
• Low: < 7 days

Automated Backups

Backup Script

#!/bin/bash
# backup.sh

DATE=$(date +%Y%m%d)
BACKUP_DIR="/backups"

# Backup database
pg_dump database_name > $BACKUP_DIR/db-$DATE.sql

# Backup files
tar -czf $BACKUP_DIR/files-$DATE.tar.gz public/uploads/

# Upload to cloud
aws s3 cp $BACKUP_DIR/ s3://backup-bucket/ --recursive

# Cleanup old backups
find $BACKUP_DIR -type f -mtime +30 -delete

Cron Schedule

# Daily backup at 2 AM
0 2 * * * /path/to/backup.sh

# Weekly backup on Sunday
0 3 * * 0 /path/to/weekly-backup.sh

Backup Verification

Test Restores

• Monthly: Test restore procedure
• Quarterly: Full disaster recovery drill
• Document: Document any issues

Verification Checklist

• [ ] Backup files exist
• [ ] Backup files are readable
• [ ] Database backup restores successfully
• [ ] File backup restores successfully
• [ ] Application works after restore

Security

Backup Encryption

# Encrypt backup
gpg --encrypt --recipient backup@example.com backup.tar.gz

Secure Storage

• Encrypt backups
• Use secure storage
• Limit access
• Audit access logs

Best Practices

1. Regular Backups

• Automated daily backups
• Test restore procedures
• Document backup process

2. Multiple Locations

• Primary backup location
• Secondary backup location
• Offsite backup

3. Version Control

• Use Git for code
• Version database backups
• Tag important backups

4. Monitoring

• Monitor backup success
• Alert on backup failures
• Review backup logs
