Publication number: US20220012360A1
Application number: 17/486,542

Abstract:
In a public cloud that stores data in a database system for a plurality of entities as primary data and as one or more secondary backup copies of the primary data, the data being stored in predefined data fields of data records, personal private data of each entity is stored encrypted using an encryption/decryption key that is unique to each different entity. The encryption/decryption keys are stored in the cloud in a key store of a key management system. To delete the personal private data of a particular entity, as to comply with the right to be forgotten pursuant to GDPR regulations, or otherwise, the encryption/decryption key for that particular entity is deleted from the key store to render permanently inaccessible all copies of that entity's personal private data.

Publication number: US20210397657A1
Application number: 17/467,604

Abstract:
The described technology is generally directed towards quasi-listing table entries that facilitate the efficient return of an object list in response to a query for relevant objects in a data storage system. A quasi-listing table entry is created when an object is created, and subsequently converted to a normal listing table entry. A normal listing table entry is converted to a quasi-listing table entry when an object is deleted, with the quasi-listing table entry subsequently deleted. When an object list request is received, a normal listing table entry can be used directly to add to the object list; only if a quasi-listing table entry is encountered (before it can be converted or deleted) does the object table need to be accessed to determine if the object actually exists. This eliminates most object table accesses, including those in remote geographic zones, thereby making object listing significantly more efficient.

Publication number: US20210389892A1
Application number: 17/446,270

Abstract:
A multi-stream restore method for reducing restore time of file data to service an external read request for file data stored by a data deduplication system employs a per-file read-ahead cache that is populated by multiple parallel internal read-ahead streams. The number of parallel read-ahead streams is dynamically variable based upon processing conditions and a set of heuristically pre-determined criteria that characterize the file data including a data access pattern that is sequential and a processing load that is below a predetermined threshold. Processing conditions are periodically monitored and adjustments to the multi-stream data access are made to optimize performance.
