1. A method for partially synchronizing primary data files based on using backup and restore operations of associated portions thereof in a storage management system, the method comprising:

  • receiving, by a first data agent executing on a first client computing device in a storage management system, from a storage manager that manages storage operations in the storage management system, first metadata that identifies a first portion of a first primary data file, wherein the first primary data file comprises data generated by the first client computing device, and wherein the first primary data file is associated with the first data agent;

    detecting, by the first data agent, at least one change in the first portion of the first primary data file;

    transmitting, by the first data agent to the storage manager, notice of the detected at least one change in the first portion of the first primary data file;

    executing, by the first data agent in conjunction with a media agent, as instructed by the storage manager, a backup operation of the first portion of the first primary data file, wherein the backup operation generates a secondary copy of the first portion of the first primary data file, wherein the secondary copy of the first portion is stored by the media agent to a secondary storage device in a backup format that is not directly accessible to the first client computing device;

    executing, by a second data agent in conjunction with the media agent, as instructed by the storage manager, a restore operation of the secondary copy to a second portion of a second primary data file,based on an association for mutual synchronization between the first portion of the first primary data file and the second portion of the second primary data file maintained by the storage manager,wherein the second primary data file is associated with the second data agent, which executes on a second client computing device in the storage management system,wherein the restore operation transforms the secondary copy of the first portion from the backup format to a native format that is directly accessible as primary data to the second client computing device; and

    wherein the first primary data file and the second primary data file are partially synchronized relative to the associated first portion and the second portion, respectively, based on the backup operation of the first portion and further based on the restore operation of the secondary copy of the first portion to the second portion of the second primary data file.
