Data protection in storage systems

A system, comprising:

• memory;
• first storage location coupled to the memory;
• second storage location coupled to the memory;
• and
• processor coupled to the memory, wherein the processor is capable of performing operations, the operations comprising:
• (i) receiving a command for writing data to the first storage location;
• (ii) determining that previously written data is stored in the first storage location;
• (iii) copying the previously written data to the second storage location, in response to determining that the previously written data is stored in the first storage location;
• and
• (iv) writing the data to the first storage location, in response to copying the previously written data to the second storage location.

An article of manufacture, wherein the article of manufacture is capable of causing operations in a machine, the operations comprising:

• receiving a command for writing data to a first storage location;
• determining that previously written data is stored in the first storage location;
• copying the previously written data to a second storage location, in response to determining that the previously written data is stored in the first storage location;
• and
• writing the data to the first storage location, in response to copying the previously written data to the second storage location.

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

• receiving a command for writing data to a first storage location;
• determining that previously written data is stored in the first storage location;
• copying the previously written data to a second storage location, in response to determining that the previously written data is stored in the first storage location;
• and
• writing the data to the first storage location, in response to copying the previously written data to the second storage location.
