Publication number: 20200068038Abstract: The disclosed embodiments disclose techniques for managing cloud-based storage using a time-series database. A distributed cloud data management system (DCDMS) manages objects stored in a cloud storage system. The DCDMS leverages a distributed time-series database to track objects accessed via the DCDMS. During operation, the DCDMS receives a request to access an object using a path identifier and an object identifier. The DCDMS determines from the path identifier that the request is associated with one of its supported extended capabilities, and uses the previously tracked object operations that are stored in the time-series database to determine the actual target bucket in the cloud storage system that contains the requested object; the target bucket that contains the object may be different from the bucket identified in the path identifier that is received. The object identifier is then used to access the requested object from the target bucket to service the request.Type: ApplicationFiled: December 11, 2018Publication date: February 27, 2020Applicant: Panzura, Inc.Inventors: Jian Xing, Qian Zhang, Pu Paul Zhang

Patent number: 9268689Abstract: The present disclosure provides for performing virus scans at a storage device that stores one or more virtual machine disk image files (VMDK files). A secure AV module can coordinate communication between a file system on the storage device, a file system (FS) decoder, and an anti-virus engine to perform a virus scan of files contained within a VMDK file. A secure AV module can determine a subset of files that include changed data, where the subset of files is stored in a file system volume within a VMDK file. The secure AV module can use an FS decoder to translate file addresses relative to the file system volume into file addresses relative to the network storage file system. A secure AV module can provide the network storage file system addresses of the subset of files to the anti-virus engine, which can perform a virus scan on the files.Type: GrantFiled: March 26, 2012Date of Patent: February 23, 2016Assignee: Symantec CorporationInventors: Grace Jing Chen, Ronald Karr, Venkeepuram Satish, Charles Paul Jerian, Pu Paul Zhang
