Troubleshooting

Common Issues

1. Verification Failures

   • Check backup integrity
   • Verify file permissions
   • Review checksum errors
   • Check disk space

2. Restore Test Issues

   • Verify restore path permissions
   • Check available space
   • Review restore logs
   • Validate backup format

3. Reporting Issues

   • Check log directory permissions
   • Verify report template access
   • Check disk space

Debug Mode
