1. A storage management system for partial synchronization of primary data files based on backup and restore operations of portions thereof, the storage management system comprising:

  • a first client computing device comprising a first data agent;

    a first primary storage device in communication with the first client computing device, wherein the first primary storage device comprises a first primary data file generated by the first client computing device, and wherein the first primary data file comprises a first portion;

    a second client computing device comprising a second data agent;

    a second primary storage device in communication with the second client computing device, wherein the second primary storage device comprises a second primary data file generated by the second client computing device, and wherein the second primary data file comprises a second portion;

    a secondary storage computing device comprising a media agent;

    a secondary storage device in communication with the secondary storage computing device;

    a storage manager in communication with the first client computing device, the second client computing device, and the secondary storage computing device, wherein the storage manager comprises metadata for partially synchronizing the first primary data file and the second primary data file in the storage management system;

    wherein the first data agent is configured to;

    receive, from the storage manager, first metadata that identifies the first portion of the first primary data file,detect at least one change in the first portion of the first primary data file, andback up, in conjunction with the media agent, the first portion of the first primary data file to a secondary copy of the first portion,wherein the secondary copy of the first portion is stored to the secondary storage device in a backup format; and

    wherein the second data agent is configured to;

    restore, in conjunction with the media agent,the secondary copy of the first portion from the secondary storage device to the second portion of the second primary data file on the second primary storage device,thereby transforming the secondary copy of the first portion from the backup format to a native format accessible as primary data to the second client computing device;

    wherein after the backup and restore operations, the first portion of the first primary data file and the second portion of the second primary data file are synchronized with each other without the rest of the first primary data file and the rest of the second primary data file being respectively synchronized with each other,thereby the first primary data file and the second primary data file being partially synchronized based on backup and restore operations in the storage management system.
