Abstract: A method, system, and computer program product for intercepting IO to a virtual machine file system by a storage based splitter, replicating, via a replication appliance, the IO to a replica of the image; the replica of the image containing a replica of the virtual machine file system, and periodically mounting the replica of the virtual machine file system to create entries for a database tracking information about the virtual machines running in the hypervisor.

Abstract: Example embodiments relate to methods, systems, and a computer program product for detecting and responding to the presence of malware persistently executing in a monitored virtual machine of a virtual computing platform. The method includes logging I/O requests at a hypervisor kernel in a kernel log and at a virtual machine (VM) managed by the hypervisor in a VM log. The logged I/O requests then may be compared to detect evidence of malware according to differences between the I/O requests logged in the VM log and the kernel log.

Abstract: A method, computer program product, and computing system for associating a tracking file with a multi-portion data file located on a data array. The tracking file is configured to monitor the status of each portion of the multi-portion data file. At least one portion of the multi-portion data file is modified via a virtual machine executed on a first physical machine. The tracking file is updated to reflect the modification of the at least one portion of the multi-portion data file.
