摘要： A method for dynamic consistency group formation, in one embodiment, includes creating a snapshot of first data stored on a source storage system with respect to data content and data structure, copying the snapshot to a target storage system, detecting one or more write operations affecting data on the source storage system while copying the first data, detecting one or more collisions affecting the first data on the source storage system, wherein a collision occurs whenever the write operations affect the first data prior to the first data being written, setting a consistency group interval which represents an interval duration between successive snapshot create-and-copy events, and altering the consistency group interval to minimize collisions affecting data on at least one of the storage systems. Other methods for dynamic consistency group formation are also described.

摘要： Provided are a computer program product, system, and method for determining whether to extend a drain time to copy data blocks from a first storage to a second storage. A data structure is generated indicating data blocks in the first storage to copy to the second storage. A drain operation is initiated to copy the data blocks indicated in the first storage to the second storage for a drain time period. Write requests to the data blocks indicated in the data structure are queued during the drain time period, wherein the queued write requests are not completed while queued. Metric information based on the writes that occur to data blocks in the first storage are gathered during the drain time period; and in response to expiration of the drain time period, a determination is made from the gathered metric information of whether to continue the drain operation or terminate the drain operation.

摘要： Provided are a method, system, and article of manufacture for iterative data secret-sharing transformation and reconversion. In one aspect, data secret-sharing transformation and reconversion is provided in which each bit of an input stream of bits of data is split, on a bit by bit basis, into a pair of secret-sharing bits, and the secret-sharing bits of each pair of secret-sharing bits are separated into separate streams of secret-sharing bits. In this manner, one secret-sharing bit of each pair of secret-sharing bits may be placed in one stream of secret-sharing bits and the other secret-sharing bit of each pair may be placed in another stream of secret-sharing bits different from the one stream of secret-sharing bits. Confidentiality of the original input stream may be protected in the event one but not both streams of secret-sharing bits is obtained by unauthorized personnel. In another aspect, for an input stream of N bits, each received bit of the N bits of the input stream of data, may be interatively split, on a bit by bit basis, into a pair of secret-sharing bits, to generate as few as N+1 secret-sharing bits from the input stream of bits N bits. Other features and aspects may be realized, depending upon the particular application.
