| description | Techniques for generating parities and repairing data erasures using repair-optimal parities are disclosed. The system includes an encoding module, which receives a request to recreate data for a subset of a plurality of content stores. The encoding module generates a new first parity and a new second parity using a subset of remaining content from the plurality of content stores. The encoding module generates a first portion of the requested data using the new first parity and a first subset of an original first parity for the plurality of content stores and a second portion of the requested data using the new second parity and a second subset of an original second parity for the plurality of content stores. The encoding module may recreate the data for the content store using the first portion of the requested data and the second portion of requested data. |
