Abstract

An example embodiment includes a distributed file management system. The distributed file management system includes a central storage device that is communicatively coupled to data repositories configured to store one or more files. The central storage device includes a processor and a tangible computer-readable storage medium. The tangible computer-readable storage medium is communicatively coupled to the processor and has computer-executable instructions stored thereon that are executable by the processor to perform operations. The operations include receiving file access requests from the data repositories. The operations also include transmitting location information of files requested in the file access requests. The location information includes internet protocol (IP) addresses of the data repositories on which the files are stored. The operations also include receiving updated file indices from the data repositories indicating remote access to files and updating a central access log and a central file index to include the updated file indices.

Claims20

Dependent claims

A distributed file management system that is implemented for a user who is associated with each of a plurality of data repositories, the distributed file management system comprising:

a central storage device communicatively coupled to the plurality of data repositories that are configured to store one or more files, the central storage device including a processor and a tangible computer-readable storage medium communicatively coupled to the processor, the tangible computer-readable storage medium having computer-executable instructions stored thereon that are executable by the processor to perform operations including:
receiving a file access request from a first data repository, the file access request including a request for a file;
authenticating the first data repository as one of the plurality of data repositories included in the file management system;
transmitting authentication information of the first data repository to a second data repository on which the file is stored, the authentication information of the first data repository indicating that the first data repository is one of the plurality of data repositories, the first data repository is a secured device, and remote access by the first data repository does not introduce vulnerabilities;
transmitting authentication information of the second data repository to the first data repository, the authentication information of the second data repository indicating that the second data repository is one of the plurality of data repositories, the second data repository is a secured device, and remote access to the second data repository does not introduce vulnerabilities;
transmitting, to the first data repository, location information of the file requested in the file access request, the location information including an internet protocol (IP) address of the second data repository on which the file is stored and enabling direct access to the file by the first data repository;
receiving updated file indices from the first and the second data repositories indicating remote access to the file at the IP address by the first data repository;
and
updating a central access log and a central file index to include the updated file indices.

6 more elements

A method comprising:

receiving, from a first data repository, a file access request for a first file, the file access request including authentication information of the first data repository;
authenticating, based on the received authentication information, the first data repository as one of a plurality of data repositories included in a file management system that is implemented for a user who is associated with each of the plurality of data repositories;
retrieving location information of the first file, the location information including a network address of a second data repository that is one of the plurality of data repositories on which the first file is stored;
transmitting authentication information of the first data repository to the second data repository, the authentication information of the first data repository indicating that the first data repository is one of the plurality of data repositories, the first data repository is a secured device, and remote access to the first data repository does not introduce vulnerabilities;
transmitting authentication information of the second data repository to the first data repository, the authentication information of the second data repository indicating that the second data repository is one of the plurality of data repositories, the second data repository is a secured device, and remote access to the second data repository does not introduce vulnerabilities;
and
transmitting the location information to the first data repository, the location information enabling direct access to the first file at the network address by the first data repository.

4 more elements

One or more processors configured to execute computer instructions to cause one or more computing systems to perform operations for remotely accessing files in a distributed file management system that is implemented for a user who is associated with each of a plurality of data repositories, the operations comprising:

communicating a file access request to a central storage device, the file access request being for a first file stored on one of the plurality of data repositories that are also communicatively coupled to the central storage device;
receiving a network address of a second data repository;
receiving authentication information of the second data repository on which the first file is stored, the authentication information indicating that the second data repository is one of the plurality of data repositories, the second data repository is a secured device, and remote access to the second data repository does not introduce vulnerabilities;
and
in response to the received authentication information, remotely accessing the first file on the second data repository at the received network address of the second data repository.
