FILE IMMUTABILITY USING A DEDUPLICATION FILE SYSTEM IN A PUBLIC CLOUD USING SELECTION DURATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240104057 titled 'FILE IMMUTABILITY USING A DEDUPLICATION FILE SYSTEM IN A PUBLIC CLOUD USING SELECTION DURATION

Simplified Explanation

The patent application describes a method for providing file immutability for cloud storage data by using a deduplicating filesystem and spawning a new filesystem to receive redirected live data, after which the old filesystem is expired. Data objects are stored in the cloud with a protection duration and a selection period to protect a subset of data objects. A retention lock is applied to the subset of data objects in cloud storage during the protection duration to prevent unauthorized deletion, modification, or movement of the data. A cloud bucket is created to store the subset of data objects, and a new filesystem is spawned for attachment to the cloud bucket. Upon expiration of the selection period, the retention locks are expired, and the new filesystem is destroyed.

• Data objects stored in the cloud have file immutability through a protection duration and selection period.
• Retention locks are applied to prevent unauthorized deletion, modification, or movement of the data.
• A new filesystem is spawned to receive live data, and the old filesystem is expired upon completion of the selection period.

Potential Applications

The technology described in the patent application could be applied in cloud storage services, data archiving solutions, and compliance-driven industries where data immutability is crucial.

Problems Solved

This technology solves the problem of ensuring the integrity and security of data stored in the cloud by providing file immutability through retention locks and a deduplicating filesystem.

Benefits

The benefits of this technology include enhanced data protection, compliance with regulatory requirements, prevention of unauthorized data tampering, and efficient management of data storage in the cloud.

Potential Commercial Applications

The technology could be commercially applied in cloud storage platforms, data management services, and industries with strict data retention policies, such as healthcare, finance, and legal sectors.

Possible Prior Art

One possible prior art for this technology could be existing solutions for data immutability in cloud storage, such as blockchain-based storage systems or encryption methods for securing data integrity.

Original Abstract Submitted

embodiments for providing file immutability for cloud storage data in a deduplicating filesystem and using a new filesystem that is spawned to receive redirected live data, after which the old filesystem is expired. data objects are stored in the cloud by defining a protection duration from a first date to a fixed future date and a selection period to select a subset of data objects to be protected during the protection period. a retention lock is applied to the subset of data objects stored in cloud storage during the protection duration, the retention lock preventing unauthorized deletion, modification or movement of the data. a cloud bucket is created for storing the subset of data objects and a new filesystem is spawned for attachment to the cloud bucket. upon expiration of the selection period, the retention locks are expired and the new filesystem is destroyed.
