Abstract
A computational device generates a point in time copy of one or more regions of a time locked data set, in response to receiving one or more I/O operations directed to the time locked data set. The one or more I/O operations are performed on the point in time copy of the one or more regions of the time locked data set, in response to generating the point in time copy of the one or more regions of the time locked data set.
Claims21
1-25. (canceled)
A method, comprising:
- generating, by a computational device, a point in time copy of one or more regions of a data set, in response to receiving one or more Input/Output (I/O) operations directed to the data set;
- and
- performing the one or more I/O operations on the point in time copy of the one or more regions of the data set, in response to generating the point in time copy of the one or more regions of the data set.
A system, comprising:
- a memory;
- and
- a processor coupled to the memory, wherein the processor performs operations, the operations comprising:
- generating a point in time copy of one or more regions of a data set, in response to receiving one or more Input/Output (I/O) operations directed to the data set;
- and
- performing the one or more I/O operations on the point in time copy of the one or more regions of the data set, in response to generating the point in time copy of the one or more regions of the data set.
A computer program product, the computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to perform operations on a processor of a computational device, the operations comprising:
- generating, by the computational device, a point in time copy of one or more regions of a data set, in response to receiving one or more Input/Output (I/O) operations directed to the data set;
- and
- performing the one or more I/O operations on the point in time copy of the one or more regions of the data set, in response to generating the point in time copy of the one or more regions of the data set.
