Abstract: Provided are a method, system, and article of manufacture for determining whether data written to source storage locations according to a write order is copied to corresponding target storage locations in the write order. Values are written to indicated source storage locations in a write order. The values written to the source storage locations are copied to corresponding target storage locations. The values at the target storage locations are read and a determination is made from the read values whether the values were written to the target storage locations in the write order.

Abstract: 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.

Abstract: 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. 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.

Abstract translation: 在本说明书的一个方面，提供一种数据保存功能，用于在时间点上保存源存储设备上的一组数据，并且包括根据先前的更新使用（诸如输入/输出使用）的功能来识别 待保存的数据，与保留的数据的剩余部分相比，在数据保存操作的至少一部分期间更有可能成为更新对象的数据的一部分，并将所识别的部分 要保存到目标存储设备的数据。 另一方面，要识别的数据部分的大小是可变的。 在一个实施例中，要识别的数据部分的大小是命令的参数的函数，使得用户可以指定影响被预写到目标存储设备的数据部分的大小的命令参数 。 该参数可以是例如要保留的数据的百分比，使得用户可以指定被预写到目标存储设备的时间点数据的百分比。 或者，参数可以是例如冲突发生的概率，使得用户可以指定碰撞发生的概率。 可以根据具体应用实现其它特征和方面。

Abstract: 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.
