In an IT system or application, thousands of events occur every second: a user signs in, data is fetched from a database, a server is rebooted, or a firewall blocks a threat. All these actions turn into records often called the system’s “digital footprints.” These records are called Logs.

Quantum computers apply the principles of quantum mechanics (superposition, entanglement, interference) directly to computation, exploring regions of the solution space that are intractable for classical machines. The goal is to unlock new capabilities across science, finance, and AI.

Backup is the insurance against risks. A well-architected backup program restores data within the target time and loss thresholds (RTO/RPO), ensuring business continuity. In this guide, we cover core concepts, backup types, and best practices with a focus on the 3-2-1 (and 3-2-1-1-0) rule.

In corporate environments, databases are the heart of data. The most critical information – from customer records and financial transactions to operational logs and product data – is stored in these systems. Therefore, database security is not just a technical topic; it is a strategic necessity for business continuity, regulatory compliance, and brand reputation.

Network recovery is not merely about restoring corporate network infrastructure to operational status, but rather the process of re-establishing this infrastructure's integrity, confidentiality, and availability in alignment with predefined business objectives and regulatory frameworks. Cyber attacks, configuration errors, hardware failures, human operational errors, or physical disasters constitute typical event classes that trigger this process.
