Abstract
A cluster of computer systems, each of which is configured with a virtualization software layer to support execution of virtual computing instances, includes a first computer system in which a first virtual computing instance is executing, the first computer system including a first local storage unit in which a first log file is stored to capture write operations to a virtual disk of the first virtual computing instance. The cluster also includes a second computer system, networked to the first computer system, in which a second virtual computing instance is executing, the second computer system including a second local storage unit in which a second log file is stored to capture write operations to a virtual disk of the second virtual computing instance and in which a replica of the first log file is stored.
