Invention of File Storage Device with Advanced Data Storage and Recovery Mechanisms

Strategic Insights -

The World Intellectual Property Organization has published patent WO/2011/121905, titled "FILE STORAGE DEVICE, DATA STORE METHOD AND DATA STORE PROGRAM," filed by NEC Corporation on March 11, 2011. The invention, credited to Japanese inventor Satoshi Yamakawa, presents an innovative file storage device and data storage method that enhances data recovery and storage efficiency. The device employs an extraction unit, a duplicate assessment unit, a store processing unit, and a restoration unit to manage data storage and retrieval.

Key Takeaways:

  • The invention proposes a file storage device that extracts independently available data from a file and assesses its presence in a store means.
  • The extraction unit extracts data that can be stored in a store means as an independent file, while the duplicate assessment unit evaluates whether the extracted data has been stored in the store means.
  • The store processing unit stores the independently available or remaining data that does not match the stored data in the store means, enabling efficient data storage and recovery.
  • The restoration unit, upon receiving a request from a client device, combines the independently available and remaining data to restore the original file.
  • This invention provides a novel approach to data storage and recovery, securing the extraction, assessment, and storage of data in a store means.
  • The use of the duplicate assessment unit ensures that only unique data is stored, minimizing storage space and enhancing data efficiency.
  • The device incorporates a store processing unit to manage data storage and recovery, streamlining the process and reducing errors.
