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： Provided are, among other things, systems, methods and techniques for controlling data synchronization. Local data-writing operations, made across a number of logical storage units on different data-storage devices, are divided into batches, the batches corresponding to different time segments. The data-writing operations, together with an indication of boundaries between the batches, are transmitted to a remote data-storage location. The boundaries between the batches are determined by at least one of: (1) identifying a period of time of sufficient duration during which no data-writing operations were performed and declaring a point during said period of time as one of the boundaries, (2) obtaining agreement from a plurality of entities, and (3) declaring the boundaries at pre-scheduled points in time.

摘要： A method and a system for data migration are described, the method for data migration including: slicing data in an original system to obtain a data slice; importing the data slice into a new system; and redoing, in the new system, respective data corresponding to at least one pre-recorded write request according to a sequence number order of the at least one pre-recorded write request, wherein the at least one pre-recorded write request above is to simultaneously write to both the original system and the new system. In the method and the system, data in an original system can be seamlessly imported to a new system without forbidding writes to the original system, and the data in the new system can be recovered to the latest by a redo technique. Without any awareness of users, the data migration can be achieved in the background.

摘要： According to one aspect of the invention, a storage system comprises: a plurality of storage devices; and a controller operable to manage a secondary volume, of a remote copy pair with a primary volume of another storage system, and corresponding to a portion of the plurality of storage devices. The secondary volume has a function for storing data included in journal data sent from said another storage system according to a remote copy procedure. The controller is operable to handle the journal data to be stored temporarily in a third volume corresponding to another portion of the plurality of storage devices before storing the data of the journal data to the secondary volume, if a relationship between the journal data and another journal data, which has smaller sequence number than sequence number of the journal data and is sent from said another storage system to the storage system, has a condition.

摘要： A multi-cloud data replication method includes providing a data replication cluster comprising at least a first host node and at least a first online storage cloud. The first host node is connected to the first online storage cloud via a network and comprises a server, a cloud array application and a local cache. The local cache comprises a buffer and a first storage volume comprising data cached in one or more buffer blocks of the local cache's buffer. Next, requesting authorization to perform cache flush of the cached first storage volume data to the first online storage cloud. Upon receiving approval of the authorization, encrypting the cached first storage volume data in each of the one or more buffer blocks with a data private key. Next, assigning metadata comprising at lest a unique identifier to each of the one or more buffer blocks and then encrypting the metadata with a metadata private key. Next, transmitting the one or more buffer blocks with the encrypted first storage volume data to the first online cloud storage. Next, creating a sequence of updates of the metadata, encrypting the sequence with the metadata private key and then transmitting the sequence of metadata updates to the first online storage cloud.
