File system indexing of backup slices for large virtual machines

A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method, the method comprising:

• obtaining, by a backup agent, a backup request for a full backup of a VM;
• in response to the backup request:
• performing a logical slicing of VM data associated with the VM to obtain a set of logical slices;
• initiating generation of a backup of each logical slice in the set of logical slices to obtain a set of backup slices;
• storing the set of backup slices in a backup storage system;
• after storing the set of backup slices, obtaining backup metadata associated with the VM from the backup storage system;
• performing, using the backup metadata, a slice file system analysis on each backup slice of the set of backup slices associated with the VM to obtain file system information for a portion of VM data stored in each backup slice of the set of backup slices;
• and
• generating, from each backup slice associated with the full backup, a file indexing system for each backup slice in the set of backup slices using the file system information.

A system, comprising:

• a processor;
• and
• memory comprising instructions, which when executed by the processor, perform a method, the method comprising:
