A method includes quiescing a file system of source storage system through a backup engine associated with the source storage system and a destination storage system and capturing, at the source storage system, a point-in-time image of the file system thereof through the backup engine. The method also includes sharing the captured point-in-time image of the file system of the source storage system with the destination storage system to enable the storage systems to have a common base data and negotiating between the storage systems for the common base data. Further, the method includes applying, to the common base data at the source storage system, a differential change corresponding to a difference between the common base data and a point-in-time image of the file system of the source storage system backed up at the destination storage system. |
