We teach how systems actually recover
Real disaster recovery skills taught through structured seminars and concrete scenarios you'll encounter in production.

Why we focus on the mechanics, not the theory
Most disaster recovery education stops at frameworks and checklists. But when a production database goes down at 3am, you need to know exactly which commands to run, in which order, and what each step actually does to your data.
We started B&W WORLD SPÓŁKA Z OGRANICZONĄ ODPOWIEDZIALNOŚCIĄ because we kept seeing the same gap — people who understood recovery concepts but froze when facing real data loss. Our seminars walk through actual recovery procedures step by step.
You'll work with backup sets, test restore operations, identify corruption, and troubleshoot recovery failures. Not hypothetically — with real systems and real data scenarios.
The students who finish our program can rebuild a crashed server from backup media and verify data integrity without second-guessing every command. That's the difference between knowing about disaster recovery and actually doing it.
How we structure the learning
Three pillars that turn backup theory into reliable recovery execution under pressure.
Real failure scenarios
Every seminar session includes recovery drills with actual failure conditions — corrupted databases, missing backup files, network timeouts during restore operations. You learn by fixing things that are genuinely broken.
Technical depth first
We explain what happens at the filesystem level during backup creation and restoration. Understanding the underlying mechanics helps you diagnose problems when automated tools fail or behave unexpectedly.
Documentation habits
Recovery procedures only work if they're documented accurately and kept current. We teach systematic documentation practices that make your runbooks actually usable during emergencies.
Who's teaching these seminars
Our instructors have spent years responding to actual data disasters in production environments. They know which recovery techniques work under pressure and which ones fall apart when you need them most.
Valter Enqvist
Lead Disaster Recovery InstructorValter spent eight years as a database reliability engineer at a financial services company, where he rebuilt systems from backup more times than he'd prefer to remember. That experience taught him exactly what works when you're trying to restore 400GB of transactional data at 4am.
He now focuses on teaching the specific technical skills that make the difference between a smooth recovery and three hours of troubleshooting failed restore operations. His seminars emphasize hands-on practice with backup verification, restore testing, and corruption detection.
Students appreciate his detailed explanations of filesystem behavior during backup operations and his systematic approach to documenting recovery procedures that actually function under stress.
What you'll build through the program
Four distinct skill areas that prepare you to handle real backup and recovery operations confidently.
Backup architecture
Design backup schedules that balance storage costs with recovery requirements. Understand incremental versus full backups at a technical level.
Restore procedures
Execute complete system recoveries from backup media. Verify data integrity after restoration and troubleshoot common failure modes.
Testing protocols
Build automated backup testing systems that catch corruption before you need to restore. Document test procedures that run consistently.
Recovery planning
Create disaster recovery documentation that works under pressure. Estimate recovery time objectives based on actual backup sets and network bandwidth.
