    摘要: In one aspect, a method to perform initialization prior to replication includes marking a first point in a delta marking stream, generating a copy of a local volume at the first point and determining dirty locations between a remote volume and the copy. The copy is generated from one of taking a snapshot or taking a clone of the local volume.

    摘要: In one aspect, a method includes providing a continuous data protection system comprising a data protection appliance, a splitter and source volumes on a source side that are replicated to target volumes of a storage array on a target side by using a journal of write transactions; and enabling, in an image access mode, a rolling back of the target volumes on the target side from a first point in time to a selected point in time so that the target volumes contain data for the selected point in time. The selected point in time is earlier than the first point in time and the rolling back includes undoing write transactions in the journal subsequent to the selected point in time; enabling generation of a virtual snapshot of the target volumes for the selected point in time after rolling back the target volumes to the selected point in time; and enabling a user to access the virtual snapshot in the storage array at the selected point in time.

    摘要: In one aspect, a method includes replicating a storage entity which is not accessible though a storage area network by using a data protection appliance (DPA) coupled to a storage area network and a data protection agent installed on a host which can access the storage entity.In another aspect, a non-transitory machine-readable medium stores executable instructions. The instructions cause a machine to replicate a storage entity which is not accessible though a storage area network by using a data protection appliance (DPA) coupled to a storage area network and a data protection agent installed on a host which can access the storage entity.

    摘要: In one aspect, a method to synchronize a replica volume with a production volume includes providing a first snapshot of the production volume and a first dirty list that includes differences between the first snapshot and the replica volume; sending only a portion of the differences between the first snapshot and the replica volume to the replica site associated with a section of the production volume, generating a second snapshot of the production volume, adding differences between the first snapshot and the second snapshot to a second dirty list, erasing the first snapshot of the production volume and renaming the second snapshot to the first snapshot.
