Latest Patents

One of his latest patents is a technique for efficiently indexing data of an archival storage system. This indexing technique provides an index data structure for efficient retrieval of a snapshot from a long-term storage service (LTSS) of an archival storage system. The snapshot is generated from typed data of a logical entity, such as a virtual disk (vdisk). The data of the snapshot is replicated to a frontend data service of the LTSS sequentially and organized as one or more data objects for storage by a backend data service of LTSS in an object store of the archival storage system. Metadata associated with the snapshot, known as snapshot metadata, is recorded as a log and persistently stored on storage media local to the frontend data service. This metadata includes information describing the snapshot data, such as a logical offset range of a snapshot of the vdisk, and is used to construct the index data structure. Notably, the construction of the index data structure is deferred until after the entirety of the snapshot data has been replicated and received by the frontend data service.

Another significant patent involves extensive recovery point management using tags. This technique enables coordination of unrelated software components to facilitate extensive recovery point management on a snapshot or recovery point through the use of a flexible tag structure. The tag is organized and arranged as a {key=value,[value] . . . } structure, wherein the key denotes an operation that requires coordination between the unrelated software components, and the value(s) denote multi-cardinality that provides parameters for coordination of the operation. The multi-cardinality aspect of the flexible tag structure provides a set of values associated with the key of the tag, enabling a software component and/or protocol to insert its value(s) into the tag structure for interpretation. This technique thus provides an extensible model where multiple components and protocols use the tag to coordinate operations on the recovery point by conveying certain meanings and interpretations of the tag and its values.
