Abstract: Techniques for initializing a replication relationship between virtual machines are described herein. The techniques include performing one or more pre-requisite checks, determining, at least partly in response to performing the one or more pre-requisite checks, one or more first data blocks associated with a first virtual machine that differ from one or more second data blocks associated with a second virtual machine. The second virtual machine may be instructed to send the one or more second data blocks that differ from the one or more first data blocks to the first virtual machine.

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.
