VMware vs Zerto

VMware, Inc. is a US software company that provides cloud and virtualization software and services, VMware's desktop software runs on Microsoft Windows, Linux, and Mac OS X, while its enterprise software hypervisors for servers, VMware ESX and VMware ESXi, are bare-metal hypervisors that run directly on server hardware without requiring an additional underlying operating system. In 1998, VMware was founded by Diane Greene, Mendel Rosenblum, Scott Devine, Edward Wang and Edouard Bugnion. Greene and Rosenblum, who are married, first met while at the University of California, Berkeley.

Zerto Ltd. is a company providing disaster recovery software for VMware-based virtual servers. The product is based on 'hypervisor-based replication', a technology that moves asynchronous replication from the physical storage and disk arrays to the virtualization abstraction layer. This allows for storage-agnostic replication; i.e., a virtual machine can be replicated to another VM operating on a different storage technology.
