Backup and Data Protection platforms capture, retain, and recover data across physical, virtual, and cloud-native environments — protecting against accidental deletion, corruption, ransomware, and infrastructure failure. Core capabilities include agent-based and agentless backup across Windows, Linux, hypervisors (VMware, Hyper-V), SaaS applications, databases, containers, and cloud-native workloads; immutable and air-gapped backup storage; encryption, deduplication, and compression; recovery-testing automation; and ransomware detection layered on backup telemetry. Modern platforms increasingly combine traditional backup with cyber-recovery capabilities as ransomware defense has become the primary driver of the category.
