Large content file optimization

A computer program product, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

• performing a backup of a primary system that includes a plurality of portions of a content file that has a size that is greater than a threshold size;
• storing plurality of portions of content file;
• and
• generating a tree data structure that provides a view of the primary system, wherein generating the tree data structure includes generating a plurality of component file metadata structures for each of the plurality of portions of the content file, wherein a component file metadata structure of the plurality of component file metadata structures corresponds to one of the portions of the content file, wherein each of the plurality of component file metadata structures includes a corresponding root node, wherein each of the plurality of component file metadata structures includes metadata that enables data chunks associated with a corresponding portion of the content file to be located, wherein the tree data structure includes a plurality of leaf nodes, wherein a first leaf node of the plurality of leaf nodes stores a first vector that indicates a size of corresponding content file data that is associated with a corresponding component file metadata structure.

A system, comprising:

• a processor configured to:
• perform a backup of a primary system that includes a plurality of portions of a content file that has a size that is greater than a threshold size;
• store the plurality of portions of the content file;
• and
• generate a tree data structure that provides a view of the primary system, wherein to generate the tree data structure, the processor is configured to generate a plurality of component file metadata structures for each of the plurality of portions of the content file, wherein a component file metadata structure of the plurality of component file metadata structures corresponds to one of the portions of the content file, wherein each of the plurality of component file metadata structures includes a corresponding root node, wherein each of the plurality of component file metadata structures includes metadata that enables data chunks associated with a corresponding portion of the content file to be located, wherein the tree data structure includes a plurality of leaf nodes, wherein a first leaf node of the plurality of leaf nodes stores a first vector that indicates a size of corresponding content file data that is associated with a corresponding component file metadata structure;
• and
• a memory coupled to the processor and configured to provide the processor with instructions.
