  • Patent number: 9223607
    Abstract: This application describes a system and techniques for managing the replication, migration, or backing up of virtual machines (VM) operating on a computing device. The techniques include managing real time or near real replication or migration of VM operations logs between computing devices. The operations logs include information or data that would enable another VM to function or operate in the same manner as the VM that generated the operations logs. Techniques are presented herein to insure the replication or migration process of VMs is not open ended or indefinite. For example, the write rate of the source operations log is managed to insure the replication or migration of the source operations log to destination device terminates within a reasonable amount of time.

  • Publication number: 20140208012
    Abstract: Techniques involving replication of virtual machines at a target site are described. One representative technique includes an apparatus including a virtual machine configured to provide storage access requests targeting a virtual disk. A storage request processing module is coupled to the virtual machine to receive the storage access requests and update the virtual disk as directed by the storage access requests. A replication management module is coupled to the virtual machine to receive the storage access requests in parallel with the storage request processing module, and to store information associated with the storage access requests in a log file(s). The log file may be transferred to a destination as a recovery replica of at least a portion of the virtual disk.
