Disclosed methods and systems leverage resources in a storage management system to partially synchronize primary data files based on synchronizing selected portions thereof without regard to changes that may be occurring in other non-synchronized portions. Accordingly, a number of primary data files may be partially synchronized by synchronizing designated portions thereof via auto-restore operations from backup data. This approach relies on storage management resources to designate portions of source data that is to be kept synchronized across any number of targets; detect changes to the designated portions; back up changes to secondary storage; and distribute the changes from secondary storage to the associated targets, with minimal impact to the primary data environment. The approach may be mutually applied, so that changes in any one of an associated group of source data files may be likewise detected, backed up, and distributed to the other members of the group. |

1. A method for partially synchronizing primary data files based on synchronizing 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, 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 a 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, at least part of 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 primary data file; executing, by a second data agent, at least part of a restore operation of the secondary copy to a second portion of a second primary data file, 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; and wherein the first primary data file and the second primary data file are partially synchronized relative to the 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. |
