Rebuilding a destination file system as part of a resync operation

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 machine to perform operations comprising:
• executing a difference operation to evaluate a clone file and a parent file to identify a set of shared blocks storing data shared by the clone file and the parent file and a set of unshared blocks storing data of the clone file that is not shared with the parent file
• creating a placeholder clone file;
• storing the set of unshared blocks into the placeholder clone file;
• and
• reconstructing the parent file as a reconstructed parent file using at least one of the set of unshared blocks of the placeholder clone file or the set of shared blocks.

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:

• executing a difference operation to evaluate a clone file and a parent file to identify a set of shared blocks storing data shared by the clone file and the parent file and a set of unshared blocks storing data of the clone file that is not shared with the parent file
• creating a placeholder clone file;
• storing the set of unshared blocks into the placeholder clone file;
• and
• reconstructing the parent file as a reconstructed parent file using at least one of the set of unshared blocks of the placeholder clone file or the set of shared blocks.
