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 intercepting write I/Os going to a volume on a storage array and sending the write I/Os to targets on a plurality of source-side data protection appliances based on a load balancing scheme. In another aspect, an article includes a non-transitory machine-readable medium that stores executable instructions. The instructions cause a machine to intercept write I/Os going to a volume on a storage array and send the write I/Os to targets on a plurality of source-side data protection appliances based on a load balancing scheme. In a further aspect, an apparatus includes circuitry configured to intercept write I/Os going to a volume on a storage array and send the write I/Os to targets on a plurality of source-side data protection appliances based on a load balancing scheme.

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.
