Storage system and methods for time continuum data retrieval

摘要

A method and system for storage of a data block for time continuum back-in-time data retrieval. The method comprises receiving a data block from a user node; updating an index stored in a memory respective of a time that the data block was received, wherein the time is a past time for retrieval of the data block; generating a hash number respective of contents of the data block; updating the index with the generated hash number; checking for existence of the generated hash number in a database; upon determination that the generated hash number does not exist in the database saving the data block in a storage device; increasing monotonously a transaction number respective of the generated hash number; and updating the index with the transaction number.

1. A method for storage of a data block for time continuum back-in-time data retrieval, comprising:
receiving a data block from a user node; updating an index stored in a memory respective of a time that the data block was received, wherein the time is a past time for retrieval of the data block; generating a hash number respective of contents of the data block; updating the index with the generated hash number; checking for existence of the generated hash number in a database; upon determination that the generated hash number does not exist in the database: saving the data block in a storage device; increasing monotonously a transaction number respective of the generated hash number; updating the index with the transaction number; receiving a request to retrieve the data block, the request including at least a past time respective of the data block to be retrieved; retrieving the transaction number respective of the past time; retrieving the data block from the storage device using the index that contains the retrieved transaction number; and providing the retrieved data block.
