Patent number: 11119860Abstract: One or more techniques and/or systems are provided for profiling a dataset. For example, a snapshot of a volume may be evaluated to identify a set of data characteristics, such as file and directory size information. A baseline dataset profile of a dataset of data within the volume may be constructed based upon the set of data characteristics. Histograms and graphs of directory counts and file counts may be constructed based upon the baseline dataset profile. An incremental dataset profile may be constructed for the dataset based upon an evaluation of the snapshot and a subsequent snapshot of the volume. Histograms and graphs of directories and files that are modified, created, and/or deleted may be constructed based upon the incremental dataset profile. Performance predictions, analytics, field diagnostics of performance issues, and/or scheduling of service execution may be implemented for a storage network hosting the volume based upon dataset profiles.Type: GrantFiled: July 2, 2019Date of Patent: September 14, 2021Assignee: NetApp Inc.Inventors: Krishna Murthy Chandraiah setty Narasingarayanapeta, Rakesh Bhargava M. R., Jose Mathew

Patent number: 11100044Abstract: A request is received to retrieve at least a portion of a file from a compressed data archived image stored in a backup storage device. The compressed data archived image comprises a backup of a file system having a number of directories and a number of files. The compressed data archived image comprises a file that includes a compression of the number of files. An address of the at least the portion of the file within the compressed data archived image is determined. The at least the portion of the file is retrieved at the address in the compressed data archived image, without decompressing the compressed data archived image.Type: GrantFiled: April 28, 2016Date of Patent: August 24, 2021Assignee: NetApp, Inc.Inventors: Sisir Shekhar, Rakesh Bhargava M R, Krishna Murthy Chandraiah setty Narasingarayanapeta

Patent number: 11086551Abstract: Techniques are provided for freeing and utilizing unused inodes. For example, an operation, targeting a first storage object of a first node having a replication relationship with a second storage object of a second node, is intercepted. A replication operation is created as a replication of the operation. The operation is implemented upon the first storage object and the replication operation is implemented upon the second storage object. A determination is made that the replication operation uses an inode no longer used by storage objects of the second node. The inode targeted by the replication operation is freed and utilized based upon the inode being a leaf inode. If the inode is a stream directory inode, then data streams of the stream directory inode are moved under a new private inode and the stream directory inode is released.Type: GrantFiled: March 19, 2019Date of Patent: August 10, 2021Assignee: NetApp, Inc.Inventors: Krishna Murthy Chandraiah setty Narasingarayanapeta, Rakesh Bhargava M.

Publication number: 20210081114Abstract: Techniques are provided for persistent hole reservation. For example, hole reservation flags of operations targeting a first storage object of a first node are replicated into replication operations targeting a second storage object of a second node during a transition operation to transition the first storage object and the second storage object from an asynchronous replication state to a synchronous replication state. In another example, the second storage object is grown to a size of a replication punch hole operation that failed due to targeting a file block number greater than an end of size of the second storage object.Type: ApplicationFiled: November 30, 2020Publication date: March 18, 2021Inventors: Krishna Murthy Chandraiah setty Narasingarayanapeta, Rakesh Bhargava M.R.

Publication number: 20200301948Abstract: Techniques are provided for timestamp consistency. An operation targeting a first storage object having a synchronous replication relationship with a second storage object is intercepted. A timestamp is assigned to the operation. A replication operation is created as a replication of the operation. The same timestamp is assigned to the replication operation. The operation is implemented upon the first storage object and the replication operation is implemented upon the second storage object.Type: ApplicationFiled: March 19, 2019Publication date: September 24, 2020Inventors: Krishna Murthy Chandraiah setty Narasingarayanapeta, Rakesh Bhargava M.R., Harsha Handral Sridhara

Patent number: 10684918Abstract: One or more techniques and/or computing devices are provided for restarting a dump backup. For example, a phase offset table is used to track a directory transfer phase offset and a file transfer phase offset of phases of a dump backup. An offset map is used to map inodes, of data being backed up, to offsets within a backup image within which the data is being backed up. The phase offset table and/or the offset map are evaluated using a bytes written value to identify a phase during which the dump backup aborted and to identify a restart point. Accordingly, the dump backup is restarted at the restart point. In this way, the dump backup may be restarted during any phase and/or at any point using the bytes written value, the phase offset table, and the offset map without the need for additional information such as a file history.Type: GrantFiled: March 16, 2016Date of Patent: June 16, 2020Assignee: NetApp Inc.Inventors: Krishna Murthy Chandraiah setty Narasingarayanapeta, Vijay Srinath, Rakesh Bhargava M R

Publication number: 20190311049Abstract: Techniques are provided for replay of metadata and data operations. During initial execution of operations, identifiers of objects modified by the execution of each operation are identified and stored in association with the operations. When the operations are to be replayed (e.g., executed again, such as part of a replication operation or as part of flushing content from a cache to persistent storage), the identifiers are evaluated to determine which operations are independent with respect to one another and which operations are dependent with respect to one another. In this way, independent operations are executed in parallel and dependent operations are executed serially with respect to the operations from the dependent operations depend.Type: ApplicationFiled: April 4, 2018Publication date: October 10, 2019Inventors: Rakesh Bhargava M R, Krishna Murthy Chandraiah setty Narasingarayanapeta
