Execution of point-in-time copy operations in continuous mirroring environments

A system, comprising:

• memory;
• and
• processor coupled to the memory, wherein the processor performs operations, the operations comprising:
• (i) receiving a point-in-time copy operation command for a point-in-time copy of a point-in-time source volume to a point-in-time target volume while performing continuous copy operations from continuous copy source volumes to continuous copy target volumes via a continuous copy operation command;
• (ii) determining whether the point-in-time target volume is a first continuous copy source volume and whether the point-in-time source volume is a second continuous copy source volume;
• (iii) determining metadata corresponding to the point-in-time copy operation, in response to determining that the point-in-time target volume is the first continuous copy source volume and the point-in-time source volume is the second continuous copy source volume;
• (iv) generating, by a storage manager application, an enhanced continuous copy operation command by augmenting the continuous copy operation command with the determined metadata corresponding to the point-in-time copy operation;
• and
• (v) applying the enhanced continuous copy operation command to perform point-in-time copy operations on the continuous copy target volumes based on the determined metadata to execute the point-in-time copy operation command while performing the continuous copy operations.

A computer readable storage medium, wherein code stored in the computer readable storage medium when executed by a machine causes operations to be performed, the operations comprising:

• receiving a point-in-time copy operation command for a point-in-time copy of a point-in-time source volume to a point-in-time target volume while performing continuous copy operations from continuous copy source volumes to continuous copy target volumes via a continuous copy operation command;
• determining whether the point-in-time target volume is a first continuous copy source volume and whether the point-in-time source volume is a second continuous copy source volume;
• determining metadata corresponding to the point-in-time copy operation, in response to determining that the point-in-time target volume is the first continuous copy source volume and the point-in-time source volume is the second continuous copy source volume;
• generating, by a storage manager application, an enhanced continuous copy operation command by augmenting the continuous copy operation command with the determined metadata corresponding to the point-in-time copy operation;
• and
• applying the enhanced continuous copy operation command to perform point-in-time copy operations on the continuous copy target volumes based on the determined metadata to execute the point-in-time copy operation command while performing the continuous copy operations.

A method for deploying computing infrastructure, comprising integrating computer-readable code into a computer, wherein the code in combination with the computer is capable of performing:

• receiving a point-in-time copy operation command for a point-in-time copy of a point-in-time source volume to a point-in-time target volume while performing continuous copy operations from continuous copy source volumes to continuous copy target volumes via a continuous copy operation command;
• determining whether the point-in-time target volume is a first continuous copy source volume and whether the point-in-time source volume is a second continuous copy source volume;
• determining metadata corresponding to the point-in-time copy operation, in response to determining that the point-in-time target volume is the first continuous copy source volume and the point-in-time source volume is the second continuous copy source volume;
• generating, by a storage manager application, an enhanced continuous copy operation command by augmenting the continuous copy operation command with the determined metadata corresponding to the point-in-time copy operation;
• and
• applying the enhanced continuous copy operation command to perform point-in-time copy operations on the continuous copy target volumes based on the determined metadata to execute the point-in-time copy operation command while performing the continuous copy operations.
