Backup & Business Continuity
Enterprise data resilience from backup architecture to disaster recovery. From the 3-2-1 rule to immutable and air-gap backups, RPO/RTO metrics to ISO 22301 business continuity planning — a 12-part guide series prepared by our expert team.
What Is Backup? Why Is It Critical for Organisations?
What is backup and why is it critical for organisations? How it differs from RAID and snapshots, why ransomware targets backups, RPO/RTO and restore testing.
The 3-2-1 Backup Rule and Modern Backup Strategies

Full, Incremental and Differential Backup: Which One, When?
What is the difference between full, incremental and differential backup? How synthetic full, incremental forever, CBT and chain management affect RPO/RTO.
What Is Immutable Backup? Unchangeable Backups Against Ransomware
What is immutable backup, how do WORM and Object Lock work, and how is an unchangeable backup architecture built against ransomware? A full guide.

What is air-gap backup, how are physical and logical isolation built, and how does a Cyber Recovery Vault protect backups against ransomware?
Backup in Ransomware Attacks: How Do Attackers Target Backups?
How are backups targeted in ransomware attacks? The attack chain, backup discovery, retention sabotage and choosing a clean restore point.
What Are RPO and RTO? The Two Critical Metrics of Business Continuity
What are RPO and RTO and how are they set? BIA, tier classification, MTD, dependency mapping and real recovery targets in a ransomware scenario.
What Is Disaster Recovery (DR)? Recovery Sites and DR Scenarios
What is Disaster Recovery and how is a DR site built? Hot/warm/cold sites, failover and failback, DRaaS, cloud DR and ransomware scenarios.
Cloud Backup: BaaS and DRaaS Architectures
