System Maintenance Guide

This guide provides system administrators with comprehensive information on maintaining a Custojo installation. Regular maintenance is essential to ensure optimal performance, security, and reliability of your Custojo system.

Maintenance Schedule

Establishing a regular maintenance schedule is crucial for keeping your Custojo system running smoothly. Here's a recommended maintenance timeline:

Daily Tasks

• Monitor system logs for errors and warnings
• Verify backup completion
• Check system resource usage (CPU, memory, disk space)
• Review security alerts and login attempts

Weekly Tasks

• Apply non-critical updates and patches
• Review user activity logs
• Check database performance
• Verify integration functionality
• Run automated tests

Monthly Tasks

• Apply major updates (after testing in staging)
• Perform comprehensive security audit
• Review and optimize database performance
• Clean up temporary files and logs
• Review and update documentation

Backup Management

Backup Strategy

A robust backup strategy is essential for data protection:

1. Database Backups

   • Full daily backups
   • Incremental backups every 6 hours
   • Transaction log backups every 30 minutes

2. File System Backups

   • Daily backups of uploaded files and documents
   • Weekly full system backups
   • Incremental backups between full backups

Backup Verification

Regularly verify your backups to ensure they can be successfully restored:

1. Automated Verification

   • Run automated integrity checks on backup files
   • Verify backup checksums
   • Test automated restoration to staging environment

2. Manual Verification

   • Quarterly full restoration tests
   • Randomly select files for restoration testing
   • Document restoration procedures and results

Update Management

Update Process

Follow these steps when applying updates:

1. Preparation

   • Review release notes and documentation
   • Backup the system before updating
   • Notify users of maintenance window

2. Testing

   • Apply updates to test/staging environment first
   • Run regression tests to verify functionality
   • Check for compatibility issues with customizations

3. Deployment

   • Schedule updates during low-usage periods
   • Follow the documented update procedure
   • Monitor the system during and after updates

Performance Optimization

Database Optimization

Maintain optimal database performance:

1. Regular Maintenance

   • Run database optimization routines
   • Rebuild indexes regularly
   • Update statistics for query optimization

2. Query Optimization

   • Monitor slow queries
   • Optimize problematic queries
   • Add appropriate indexes

Application Optimization

Keep the application running efficiently:

1. Cache Management

   • Configure caching appropriately
   • Clear cache after updates
   • Monitor cache hit rates

2. File Storage

   • Implement file storage quotas
   • Archive old files
   • Optimize file storage configuration

Security Maintenance

Security Updates

Prioritize security in your maintenance routine:

1. Patch Management

   • Apply security patches promptly
   • Subscribe to security announcements

   • Review login attempt logs
   • Set up IP restrictions where appropriate

Troubleshooting

Common Issues

Solutions for frequently encountered problems:

1. Performance Issues

   • Check server resources
   • Review database query performance
   • Analyze application logs

2. Integration Problems

   • Verify API endpoints
   • Check authentication credentials
   • Review integration logs

Monitoring Tools

Implement these monitoring solutions:

1. System Monitoring

   • Set up alerts for resource usage
   • Monitor server health
   • Track response times

2. Application Monitoring

   • Log application errors
   • Track user activity
   • Monitor integration status

Best Practices

• Document all maintenance procedures
• Maintain a change log
• Create a disaster recovery plan
• Test recovery procedures regularly
