Deduplicated merged indexed object storage file system

A non-transitory computer-readable medium configured to store computer code comprising instructions, the instructions, when executed by one or more processors, causes the one or more processors to:

• generate, responsive to a creation of a first version of a file captured in a first snapshot, a first namespace entry associated with the first version, the first namespace entry comprising a first creation version corresponding to the first snapshot;
• generate, responsive to a modification of the file from the first version to a second version captured in a second snapshot, a second namespace entry associated with the first version, the second namespace entry comprising a second creation version corresponding to the first snapshot and a second deletion version corresponding to the second snapshot;
• and
• generate a third namespace entry associated with the second version, the third namespace entry comprising a third creation version corresponding to the second snapshot and a third deletion version corresponding to no snapshot.

A system comprising:

• a client device configured to store a file;
• and
• an index system in communication with the client device, the index system comprising memory and one or more processors, the memory configured to store computer code comprising instructions, the instructions, when executed by the one or more processors, cause the one or more processors to:
• generate, responsive to a creation of a first version of the file captured in a first snapshot, a first namespace entry associated with the first version, the first namespace entry comprising a first creation version corresponding to the first snapshot;
• generate, responsive to a modification of the file from the first version to a second version captured in a second snapshot, a second namespace entry associated with the first version, the second namespace entry comprising a second creation version corresponding to the first snapshot and a second deletion version corresponding to the second snapshot;
• and
• generate a third namespace entry associated with the second version, the third namespace entry comprising a third creation version corresponding to the second snapshot and a third deletion version corresponding to no snapshot.
