Updating protection sets in a geographically distributed storage environment

A method, comprising:

• receiving, by a system comprising a processor and a memory, a request to update a protection set for a first coded chunk in response to detecting deletion of a primary data chunk, wherein the first coded chunk and the primary data chunk are stored in a geographically distributed data storage system;
• generating, by the system, a transformation data chunk utilizing a secondary data chunk stored in the geographically distributed data storage system;
• and
• generating, by the system, a second coded chunk having an updated protection set, wherein the updated protection set is generated utilizing the transformation data chunk.

A machine-readable non-transitory storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

• receiving a request to update a protection set for a first coded chunk in response to detecting deletion of a primary data chunk, wherein the first coded chunk and the primary data chunk are stored in a geographically distributed data storage system;
• generating a transformation data chunk utilizing a secondary data chunk stored in the geographically distributed data storage system;
• generating a second coded chunk having an updated protection set;
• and
• updating the first coded chunk with the second coded chunk.
