MotoVaultPro Scripts

Utility scripts for database management and operations.

Database Export/Import Scripts

Quick Start

# Export full database
make db-export

# Export schema only
make db-export-schema

# Create timestamped backup
make db-backup

# Import from file
make db-import-file FILE=database-exports/backup.sql.gz

Available Scripts

export-database.sh

Exports PostgreSQL database in multiple formats with metadata and instructions.

Features:

• Multiple export formats (SQL, custom, directory)
• Automatic compression
• Schema-only or data-only exports
• Table filtering
• Generates import instructions

Usage:

# Full export
./scripts/export-database.sh

# Schema only
./scripts/export-database.sh --schema-only

# Custom format (faster for large databases)
./scripts/export-database.sh --format custom

# Specific tables
./scripts/export-database.sh --include-table vehicles --include-table fuel_logs

# Exclude tables
./scripts/export-database.sh --exclude-table audit_logs

import-database.sh

Imports PostgreSQL database with safety features and validation.

Features:

• Auto-detects export format
• Automatic backup before import
• Safety confirmations
• Database creation
• Import verification

Usage:

# Basic import
./scripts/import-database.sh database-exports/backup.sql.gz

# Create new database
./scripts/import-database.sh --create-db backup.sql.gz

# Replace existing (with confirmation)
./scripts/import-database.sh --drop-existing backup.sql.gz

# Automated import (no prompts)
./scripts/import-database.sh --drop-existing --force backup.sql.gz

Makefile Shortcuts

# Export Commands
make db-export          # Full database export
make db-export-schema   # Schema only with date
make db-export-custom   # Custom format with date
make db-backup          # Timestamped backup

# Import Commands
make db-import          # Show import help
make db-import-file FILE=path/to/backup.sql.gz

Output Files

Each export creates three files:

1. Export file (.sql.gz, .dump, or directory)

   • The actual database dump

2. Metadata file (*_metadata.json)

   • Export timestamp, format, size
   • PostgreSQL version
   • Export options used

3. Import instructions (*_import_instructions.txt)

   • Step-by-step import guide
   • Format-specific commands
   • Database preparation steps

Common Use Cases

Production Backup

# Daily backup with timestamp
make db-backup

# Result: database-exports/backup_20251102_143000.sql.gz

Development Setup

# Get schema from production
ssh prod "cd /app && ./scripts/export-database.sh --schema-only --output dev_schema"
scp prod:/app/database-exports/dev_schema.sql.gz ./database-exports/

# Import to dev
./scripts/import-database.sh --create-db database-exports/dev_schema.sql.gz

Migration Between Servers

# On source server
./scripts/export-database.sh --format custom --output migration_$(date +%Y%m%d)

# Transfer to target
scp database-exports/migration_* target:/app/database-exports/

# On target server
./scripts/import-database.sh --drop-existing database-exports/migration_20251102.dump

Selective Data Export

# Export only vehicle-related data
./scripts/export-database.sh \
  --include-table vehicles \
  --include-table fuel_logs \
  --include-table maintenance_records \
  --output vehicle_data

Safety Features

Automatic Backups

Before destructive operations, the import script automatically creates a backup:

[INFO] Creating backup: database-exports/motovaultpro_backup_20251102_143000.sql.gz
[INFO] Backup created successfully

Confirmation Prompts

Dangerous operations require explicit confirmation:

WARNING: This will DROP the existing database 'motovaultpro'
All data will be permanently deleted!

Are you sure you want to continue? (type 'yes' to confirm):

Format Validation

Scripts detect and validate file formats automatically:

[INFO] Auto-detected format: sql-compressed

Troubleshooting

Container Not Running

Error: PostgreSQL container 'mvp-postgres' is not running

Solution:
docker compose up -d mvp-postgres

Permission Issues

chmod +x scripts/export-database.sh
chmod +x scripts/import-database.sh

Large Database Exports

For databases >1GB, use custom format:

./scripts/export-database.sh --format custom --no-compress

Advanced Usage

Automated Backups with Cron

# Daily at 2 AM
0 2 * * * cd /app && ./scripts/export-database.sh --output daily_$(date +%Y%m%d) >> /var/log/db-backup.log 2>&1

# Weekly on Sunday at 3 AM
0 3 * * 0 cd /app && ./scripts/export-database.sh --format custom --output weekly_$(date +%Y%m%d) >> /var/log/db-backup.log 2>&1

Cleanup Old Backups

# Keep last 7 days of daily backups
find database-exports/ -name "daily_*.sql.gz" -mtime +7 -delete

# Keep last 4 weeks of weekly backups
find database-exports/ -name "weekly_*.dump" -mtime +28 -delete

Export for Analysis

# Export specific tables for data analysis
./scripts/export-database.sh \
  --data-only \
  --include-table fuel_logs \
  --include-table maintenance_records \
  --output analytics_data
