    摘要： Methods and systems for accessing data from a previous point in time, including receiving data stored in a storage system of addressable memory, the storage system including a plurality of addresses, receiving a journal history of write transactions for the storage, each write transaction including (i) a plurality of designated memory addresses, (ii) a corresponding plurality of current data to write in the designated memory addresses for storage, and (iii) a time indicator, generating a data structure that represents a virtual interface to the storage at a specified point in time, based on the write transactions in the journal history having a time subsequent to the specified point in time, and enabling a user to process the data from the specified point in time, via the virtual interface and the journal history.

    摘要： Method and apparatus to provide a data replication system to receive a data transfer request from a first component at a transmitter module in a continuous data replication system having a production site and a backup site, the production site having a transmitter module and a transmitter credit mechanism, the transmitter module to transmit data over a network for replication in the backup site, detect a high-load condition at the transmitter module, and modify a flow of credits from the transmitter credit mechanism to the first component to reduce or stop data flow to the transmitter module.

    摘要： A computer implemented method, computer program product, and system for continuous replication in a virtual environment comprising recovering, replication of, a volume on a first site after the crash of the first site, receiving, using an API, the differences between a previous point in time of the first volume and the current point in time of the first volume wherein the volume is being replicated to a second site, and using the determined differences to restore replication of the first volume of the replication site at the second site.

    摘要： Example embodiments of the present invention leverage the punch command and thin LUNs in order to create a fully dynamic journal which can shrink and grow on demand. The journal may be assigned a maximum allowed size, as well as a journal protection window defining a period for which the journal should retain journal information. A set of currently used blocks will be used and, if protection window is large enough, the oldest data blocks from an undo stream will be punched out from the stream. A manager may monitor how much free space there is in the storage pool and regulate the journal growth if the pool is nearly empty. Additionally, the journal capacity may also depend on the actual usage of the replicated LUNs if the replicated LUNs are thin (i.e., maintain the journal at a particular percentage of the used storage capacity).
