Abstract
A computational device receives a command to activate a time lock for a data set. In response to receiving the command to activate the time lock for the data set, a point in time copy of the data set is generated to allow write operations to be performed even if the time lock is activated.
Claims25
A method, comprising:
- receiving, by a computational device, a command to activate a time lock for a data set;
- and
- in response to receiving the command to activate the time lock for the data set, generating a point in time copy of the data set to allow write operations to be performed even if the time lock is activated.
A system, comprising:
- a memory;
- and
- a processor coupled to the memory, wherein the processor performs operations, the operations comprising:
- receiving a command to activate a time lock for a data set;
- and
- in response to receiving the command to activate the time lock for the data set, generating a point in time copy of the data set to allow write operations to be performed even if the time lock is activated.
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:
- receiving, by the computational device, a command to activate a time lock for a data set;
- and
- in response to receiving the command to activate the time lock for the data set, generating a point in time copy of the data set to allow write operations to be performed even if the time lock is activated.
A storage controller, wherein the storage controller is configured to perform operations, the operations comprising:
- receiving a command to activate a time lock for a data set;
- and
- in response to receiving the command to activate the time lock for the data set, generating a point in time copy of the data set to allow write operations to be performed even if the time lock is activated.
