摘要： In a continuous data protection system having a primary volume and a secondary volume, a method for data recovery begins by selecting a snapshot of the primary volume to be recovered and a location on which the snapshot is to be loaded. A point in time (PIT) map is created for the selected snapshot, and the selected snapshot is loaded at the selected location. A data block from the PIT map is resolved to determine which block on the secondary volume is presented as being part of the snapshot. The snapshot is accessed via a host computer as if the snapshot was the primary volume at an earlier point in time, corresponding to the time of the selected snapshot.

摘要： In a data processing system having a primary site and a secondary site, storage systems are connected to each other via a communication line, data update history is recorded in a storage device as a journal in the primary site, and the journal is transferred to the secondary site via the communication line. During such transfer, loads will not concentrate to a specific volume, by switching the volume that stores the journal in the primary site, while, by switching the transfer-destination volume of the journal in the secondary site. With such arrangement, in a data processing system, it is possible to ensure data consistency in a plurality of sites and prevent the system throughput capacity from being deteriorated without applying loads to a host and a network, and without causing load concentration on a specific storage device that is caused as a result of data update or recovery operations.

摘要： A method for browsing objects on a protected volume in a continuous data protection system begins by displaying a list of top-level objects to a user who selects a top-level object to browse. A snapshot is selected from the selected top-level object and is decoded. A list of objects in the selected snapshot is displayed and the user selects an object to browse. The selected object is decoded and operations are performed on the selected object. The user can browse the protected volume by snapshots in the top-level object or by a range of time of coverage of the top-level object.

摘要： A system and method for improving the efficiency of the transmission of updated blocks generated by logging all the block allocations and deletes as well as CPs and PCPI creation and deletion in a persistent log. The log is scanned during each update cycle (in which changes are transmitted to a destination mirror) by the storage operating system, and only changed blocks that are referenced by the file system as it existed at the end of the update cycle or referenced by PCPIs that existed at the end of the update cycle are actually sent in the transmission. This reduces the number of changes being transmitted.
摘要翻译：一种通过记录所有块分配和删除以及CP和PCPI创建和删除在持久日志中生成的更新块的传输效率的系统和方法。在存储操作系统的每个更新周期（其中更改发送到目标镜像）的每个更新周期中扫描日志，并且只有文件系统引用的已更改的块，因为它在更新周期结束时存在或由PCPI引用在更新周期结束时存在的数据实际上是在传输中发送的。这减少了正在发送的更改的数量。

摘要： A storage device system includes an information processing device and at least first and second storage devices. The first and second storage devices are equipped with first and second storage volumes, respectively. The information processing device generates first data including a first instruction that is to be executed by the second storage device, and sends a write request to a first write request section to write the first data according to a first communications protocol in the first storage volume. When the first data written in the first storage volume is the command to be executed by the second storage device, the first storage device sends to a second write request section a write request to write the first data according to a second communications protocol in the second storage volume. The second storage device executes the first command set in the first data that is written in the second storage volume.

摘要： A data processing system includes at least a first storage system, a second storage system and a third storage system. The third storage system maintains a replication of data stored in the first storage system. When updating data in the first storage system, the first storage system updates the replication of data stored in the third storage system and creates a journal. The journal is formed from a copy of data used for update and update information such as a write command for update, etc. The second storage system also maintains a replication of data stored in the first storage system. The second storage system obtains the journal, and updates data stored therein corresponding to data stored in the first storage system in the order of data update performed in the first storage system. When updating data stored in the third storage system corresponding to data stored in the first storage system, the third storage system creates a journal using data update numbers created in the first storage system. When the first storage system fails, the second storage system obtains the journal from the third storage system, and updates data stored therein corresponding to data stored in the first storage system in the order of data update performed in the first storage system.

摘要： A first storage unit system and a second storage unit system are connected together via a third storage unit system. When executing a remote copy process, the first storage unit system responds to a write request received from a computer to transmit to the third storage unit system a journal having write data and address information indicative of a storage position at which the write data is written and requests the third storage unit system to write the journal. The second storage unit system receives control information issued by the first storage unit system and including the storage position of the journal and on the basis of the control information, reads the journal from the third storage unit system. Then, the second storage unit system follows address information contained in the journal to write the write date contained in the journal to a disk inside the second storage unit system.

摘要： Methods, systems, and configured storage media are provided for flexible data mirroring. In particular, the invention provides many-to-one data mirroring, including mirroring from local servers running the same or different operating systems and/or file systems at two or more geographically dispersed locations. The invention also provides one-to-many data mirroring, mirroring with or without a dedicated private telecommunications link, and mirroring with or without a dedicated server or another server at the destination(s) to assist the remote mirroring unit(s). In addition, the invention provides flexibility by permitting the use of various combinations of one or more external storage units and/or RAID units to hold mirrored data. Spoofing, SCSI and other bus emulations, and further tools and techniques are used in various embodiments of the invention.

摘要： Techniques for performing data redundancy operations using a portal and a host computer. In one aspect, a primary data storage facility stores a primary copy of data and a secondary facility stores data that is redundant of the primary copy of the data. The primary facility includes a host computer having a first redundancy component for storing data for a sequence of write requests in storage associated with the primary storage facility and a first redundancy portal for retrieving the data and for forwarding the data to the secondary storage facility. The first redundancy portal is outside a communication path between the host computer and the storage. This prevents the redundancy portal from becoming a communication bottleneck. A second redundancy portal may be provided at the secondary facility.
