Abstract
A data restoration system including a data management server. The data management server receives one or more data restoration requests for restoring a plurality of data blocks. The data management server determines, based on metadata associated with the data blocks, a first subset of warm data blocks corresponding to warm-tier data and a second subset of cold data blocks corresponding to cold-tier data. The data management server retrieves the warm data blocks in the first subset and restores the warm data blocks in the first subset. The data management server groups the cold data blocks based in part on storage times of the cold data blocks to generate a plurality of cold-tier data retrieval requests. The data management server retrieves the cold data blocks by batches, each batch corresponding to one of the cold-tier data retrieval requests. The data management server restores the cold data blocks in the second subset.
