Large content file optimization

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

• receiving an indication to perform a backup of file system data, wherein the file system data includes a content file having a size greater than a threshold size;
• determining that the size of the content file is greater than the threshold size;
• in response to determining that the size of the content file is greater than the threshold size, generating a plurality of component file metadata structures for the content file, wherein the plurality of component file metadata structure includes at least a first component file metadata structure having a first root node and a second component file metadata structure having a second root node;
• and
• storing file metadata of the content file split across the plurality of component file metadata structures, wherein the plurality of component file metadata structures are associated with different portions of the content file, wherein a first component file metadata structure of the plurality of component file metadata structures stores a first component file metadata corresponding to a first portion of the content file, wherein the first component file metadata corresponding to the first portion of the content file includes one or more references to locations of data chunks associated with the first portion of the content file.

A system, comprising:

• a processor configured to:
• receive an indication to perform a backup of file system data, wherein the file system data includes a content file having a size greater than a threshold size;
• determine that the size of the content file is greater than the threshold size;
• in response to a determination that the size of the content file is greater than the threshold size, generate a plurality of component file metadata structures for the content file, wherein the plurality of component file metadata structure includes at least a first component file metadata structure having a first root node and a second component file metadata structure having a second root node;
• and
• store file metadata of the content file split across the plurality of component file metadata structures, wherein the plurality of component file metadata structures are associated with different portions of the content file, wherein the first component file metadata structure of the plurality of component file metadata structures stores file metadata corresponding to a first portion of the content file, wherein the first component file metadata corresponding to the first portion of the content file includes one or more references to locations of data chunks associated with the first portion of the content file;
• and
• a memory coupled to the processor and configured to provide the processor with instructions.
