Replicating clone files from a source file system to a destination file system

A computing device, comprising:

• a memory comprising machine executable code;
• and
• a processor coupled to the memory, the processor configured to execute the machine executable code to cause the computing device to perform operations comprising:
• tracking, within a metafile hosted at a first storage node of a computing system, clone relationship information between clone files and parent files at the first storage node;
• performing a difference operation upon two snapshots to identify changed data and transfer the changed data as a changed file from the first storage node to a second storage node of the computing system;
• in response to identifying changed data during the difference operation, determining whether the changed file is a clone file of a parent file based at least in part on the metafile;
• and
• in response to determining the changed file is a clone file, sending inode information of the clone file and parent file information of the parent file to the second storage node for reconstruction of the clone file at the second storage node as a reconstructed clone file using the inode information and the parent file information.

A non-transitory machine readable medium comprising instructions for performing a method, which when executed by a machine, causes the machine to perform operations comprising:

• tracking, within a metafile hosted at a first storage node of the computing system, clone relationship information between clone files and parent files at the first storage node;
• performing a difference operation upon two snapshots to identify changed data and transfer the changed data as a changed file from the first storage node to a second storage node of a computing system;
• in response to identifying changed data during the difference operation, determining whether the changed file is a clone file of a parent file based at least in part on the metafile;
• and
• in response to determining the changed file is a clone file, sending inode information of the clone file and parent file information of the parent file to the second storage node for reconstruction of the clone file at the second storage node as a reconstructed clone file using the inode information and the parent file information.
