摘要： The punch command may be replicated in a replication environment including a production site and a replication site. The solution includes implementing a punch command to free storage received at a replication site in a replication environment by applying the punch command to storage at the replication site and writing data being freed from the storage at the replication site to an undo stream of a journal at the replication site. If the punch command is not supported, a command to write zeros may be used. Further, an unpunch command is provided for properly undoing a punch command and storing data written to the volume before the punch command freed the storage. Additionally, large punch commands may be split into a plurality to smaller punch commands for efficient journal management. Additionally, volume space may be reclaimed by writing a punch command to the journal instead of zeros.

摘要： In one aspect, a method includes exposing a set of storage volumes to a host at a requested point in time, in a virtual access mode. The set of storage volumes are handled by distributed virtual consistency groups (CGs) having a background process wherein the distributed virtual CGs update the set of storage volumes to the requested point in time. The method also includes exposing a first service storage volume at a data protection appliance, determining if the virtual CGs have rolled back and using at least one of a central manager and a splitter to account for input/output requests (IOs) when a virtual CG has not rolled back.

摘要： A method, computer program product, and computing system for receiving an indication that a target virtual machine is going to be migrated from a first operating environment to a second operating environment. The target cache system is associated with target virtual machine. An auxiliary virtual machine is generated within the second operating environment. An auxiliary cache system is associated with the auxiliary virtual machine. The target virtual machine and the auxiliary virtual machine are connected. IO requests for the target virtual machine are mirrored to the auxiliary virtual machine. At least a portion of cache data included within a target memory system associated with the target cache system is copied to an auxiliary memory system associated with the auxiliary cache system. The target virtual machine is migrated from the first operating environment to the second operating environment.
