Zerto delivers continuous data protection and disaster recovery for virtualized and cloud workloads, enabling near-zero RPO recovery as a Hewlett Packard Enterprise product.
About
Zerto is a continuous data protection and disaster recovery platform that uses journal-based replication to capture every write operation to protected virtual machines and cloud workloads, maintaining a rolling recovery journal that enables point-in-time recovery to any second within the journal window rather than only to the most recent backup snapshot. This approach collapses the recovery point objective for protected workloads to near-zero — seconds rather than hours — fundamentally changing the data protection economics for organizations whose business-critical applications cannot tolerate the data loss that snapshot-based backup schedules produce. The platform's continuous replication engine operates at the hypervisor level without agents in protected VMs, capturing changes with minimal performance impact while maintaining the journal that enables granular recovery point selection.
