FILE IMMUTABILITY USING A DEDUPLICATION FILE SYSTEM IN A PUBLIC CLOUD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240020275 titled 'FILE IMMUTABILITY USING A DEDUPLICATION FILE SYSTEM IN A PUBLIC CLOUD
Simplified Explanation
The abstract describes a method for ensuring data immutability in cloud storage by using a deduplication filesystem. The method involves setting a protection duration for data objects stored in the cloud, during which a retention lock is applied to prevent unauthorized deletion, modification, or movement of the data objects. A renew threshold date is defined within the protection duration, and a garbage collection operation is performed at this date to permanently delete dead data objects and retain live data objects. The retention lock is extended on the remaining live data objects and any subsequently written data objects after the garbage collection operation.
- The method provides data immutability in cloud storage by using a deduplication filesystem.
- It sets a protection duration for data objects, during which a retention lock is applied.
- The retention lock prevents unauthorized deletion, modification, or movement of the data objects.
- A renew threshold date is defined within the protection duration.
- A garbage collection operation is performed at the renew threshold date.
- The garbage collection operation permanently deletes dead data objects and retains live data objects.
- The retention lock is extended on the remaining live data objects and any new data objects.
Potential applications of this technology:
- Data storage in cloud environments where data immutability is crucial, such as legal or financial industries.
- Secure storage of sensitive data in cloud storage systems.
- Compliance with data retention regulations and policies.
Problems solved by this technology:
- Ensures data immutability by preventing unauthorized changes or deletions.
- Provides a method for securely storing and managing data in cloud storage.
- Simplifies compliance with data retention requirements.
Benefits of this technology:
- Enhanced data security and protection against unauthorized access or tampering.
- Simplified management of data retention and compliance.
- Efficient use of storage space by permanently deleting dead data objects.
- Improved data integrity and reliability in cloud storage systems.
Original Abstract Submitted
a method for providing data immutability using a deduplication filesystem for data objects stored in the cloud by defining a protection duration from a first date to a fixed future date, and applying a retention lock to one or more data objects stored in cloud storage during the protection duration, the retention lock preventing deletion, modification or movement of the data objects by an unauthorized entity. the method defines a renew threshold date within the protection duration, and performs a garbage collection (gc) operation at the renew threshold date to permanently delete dead data objects and carry forward live data objects, and extends the retention lock on remaining live data objects and subsequently written data objects upon completion of the gc operation.
