Optimized restoration of deduplicated data

A computer-implemented method comprising:

• at a first computing device, receiving a first read request for a first data segment, wherein the first data segment is part of a backup copy that was previously generated, wherein the backup copy comprises a plurality of data segments that were stored with deduplication in a data storage system;
• and
• by the first computing device:
• responsive to the first read request, parsing one or more indexes to identify, among the plurality of data segments, a series of data segments that are stored consecutively at the data storage system such that the series includes the first data segment;
• generating an aggregated read request for the series of data segments, wherein the aggregated read request is directed at the data storage system;
• receiving the series of data segments from the data storage system;
• storing the series of data segments at the first computing device;
• serving the first data segment from the first computing device responsive to the first read request;
• and
• responsive to subsequent read requests for one or more data segments among the series of data segments, serving the one or more data segments from the first computing device, wherein the first computing device comprises one or more hardware processors and non-transitory computer memory.
