Top 10 Backup & Disaster Recovery

Backup and disaster recovery tools protect data and workloads by creating point-in-time snapshots, replicating data to secondary sites, and automating recovery procedures to meet RTO and RPO objectives. They cover Kubernetes workloads, virtual machines, databases, and cloud-native storage.

Why this category matters

Data loss from hardware failure, accidental deletion, ransomware, or regional cloud outages can be catastrophic without tested backup and recovery procedures. These tools automate protection policies and provide verified restore capabilities.

When to use these tools

Implement backup and DR tooling before you need it, especially when running stateful workloads in Kubernetes, when compliance mandates data retention policies, or when business continuity requirements define specific RTO and RPO targets.

Backup & Disaster Recovery — FAQ

What is the 3-2-1 backup rule?

The 3-2-1 rule recommends keeping 3 copies of data, on 2 different storage media types, with 1 copy stored off-site or in a different cloud region to protect against site-level disasters.

How does Velero differ from storage snapshots?

Velero backs up Kubernetes resource definitions and optionally volume data, enabling full cluster or namespace restoration to a different cluster. Storage snapshots only capture volume data without the Kubernetes configuration context.

How often should backup restores be tested?

Restore tests should run at minimum quarterly, and ideally monthly or on every backup policy change. An untested backup is not a backup — many organizations discover restore failures only when they need them most.
