🚀 Quick Start

Create First Backup

./scripts/backup-databases.sh --compress --verify

List Backups

./scripts/manage-backups.sh list

Restore Backup

./scripts/restore-databases.sh <timestamp>

Run Tests

./scripts/test-backup-system.sh

🔧 Integration Examples

Before Migration

import { backupHelper } from './src/scripts/backup-helper';

const backup = await backupHelper.createSafetyBackup('migration');
if (!backup.success) {
  console.error('Backup failed, aborting migration');
  process.exit(1);
}

Auto-Restore on Failure

try {
  await performMigration();
} catch (error) {
  await backupHelper.restoreBackup(backup.timestamp, {
    force: true
  });
  throw error;
}
