摘要： A data transfer application implemented in a computational device receives a request to copy a plurality of storage volumes that form a consistency group. A determination is made that a first storage volume of the plurality of storage volumes is more likely to be written into than a second storage volume of the plurality of storage volumes, in response to receiving the request to copy the plurality of storage volumes. The first storage volume is copied before copying the second storage volume, in response to determining that the first storage volume is more likely to be written into than the second storage volume.

摘要： In one aspect of the present description, a data preservation function is provided for preserving a set of data on a source storage device at a point in time, and includes identifying as a function of prior update usage, such as input/output usage, of the data to be preserved, a portion of the data which is more likely to be the subject of updates during at least a portion of the data preservation operation as compared to the remaining portion of the data to be preserved, and copies the identified portion of the data to be preserved to a target storage device. In another aspect, the size of the portion of data to be identified is variable. Other features and aspects may be realized, depending upon the particular application.

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.

In another aspect, the size of the portion of data to be identified is variable. In one embodiment, the size of the portion of data to be identified is a function of a parameter of the command, such that a user can specify the command parameter which affects the size of the portion of data which is prewritten to the target storage device. The parameter may be, for example, a percentage of the data to be preserved, such that a user can specify the percentage of the point-in-time data which is prewritten to the target storage device. Alternatively, the parameter may be, for example, a probability of a collision occurring, such that a user can specify a probability of a collision occurring. Other features and aspects may be realized, depending upon the particular application.

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： A method for concurrently converting a standard volume to a thin-provisioned volume includes initially establishing metadata for a thin-provisioned volume. The method then updates the metadata for the thin-provisioned volume to point to extents residing in a standard volume. The method then suspends I/O to metadata for the standard volume. Upon suspending the I/O, the method migrates control of the extents in the standard volume from a standard-volume control algorithm to a thin-provisioned-volume control algorithm. The method then resumes the I/O to the metadata for the thin-provisioned volume. Using this technique, standard volumes may be rapidly converted to thin-provisioned volumes while minimally disrupting I/O to the volumes. A corresponding apparatus and computer program product are also disclosed and claimed herein.
