| 20210034467 | TECHNIQUES FOR DUPLICATING INODE STATE TO PREVENT LOSS OF INODE METADATA - Techniques for performing processing to recover metadata may include: shadow top structures, and performing processing that uses the shadow top structures to recover information for an index node associated with an object of a file system having a file system logical address space. One of the shadow top structures is created for each metadata (MD) top node of a MD mapping structure used to determine storage locations of data stored at corresponding logical addresses in the file system logical address space. Each MD top node is used in determining storage locations for a specified subrange of logical addresses of the file system logical address space. Each shadow top structure corresponding to a MD top node describes each file system object mapped to a logical address included in the specified subrange of logical addresses of the file system address space associated with the corresponding MD top node. | 2021-02-04 |
| 20210034468 | METHOD AND SYSTEM FOR REDUNDANT DISTRIBUTION AND RECONSTRUCTION OF STORAGE METADATA - In general, the invention relates to a method for managing data, the method includes obtaining data from a host, applying an erasure coding procedure to the data to obtain a plurality of data chunks and at least one parity chunk, deduplicating the plurality of data chunks to obtain a plurality of deduplicated data chunks, generating storage metadata associated with the plurality of deduplicated data chunks and the at least one parity chunk, storing the storage metadata in an accelerator pool, storing, across a plurality of fault domains, the plurality of deduplicated data chunks and the at least one parity chunk, and initiating storage metadata distribution on the storage metadata across the plurality of fault domains. | 2021-02-04 |
| 20210034469 | OPTIMIZING SNAPSHOT IMAGE PROCESSING - Systems, methods, and machine-storage mediums for optimizing snapshot image processing are described. The system receives a first read request to read data from optimized snapshot information including snapshot information and cached snapshot information. The first read request includes a first offset identifying a first storage location and a first length. The snapshot information includes a full snapshot and at least one incremental snapshot. The system identifies a first portion of the data is stored in the snapshot information responsive to identifying the first portion of the data is not stored in the cache snapshot information. The system identifies a second portion of data is stored in the optimized snapshot information, reads the first portion of data and the second portion of data from the optimized snapshot information, and communicates the data, including the first and second portions of the data, to the job. | 2021-02-04 |

| 20210034471 | STREAMING DATABASE BACKUP USING CLUSTER LIVE MOUNTS - A database can be backed up and recovered by a cluster mapped to the database. Nodes of the cluster are mapped over channels to directories of the database. Scripts are generated. from one or more templates that specify the order and values to be executed to perform a database job, such as database backup or recovery. To initiate a given database job, a template can be executed that generates and populates scripts, which are processed on the host of the database to perform the database job in a nearly instant manner using the mapped nodes of the cluster. | 2021-02-04 |
| 20210034472 | METHOD AND SYSTEM FOR ANY-POINT-IN-TIME RECOVERY WITHIN A CONTINUOUS DATA PROTECTION SOFTWARE-DEFINED STORAGE - A method for managing data includes obtaining data from a host, applying an erasure coding procedure to the data to obtain a plurality of data chunks and at least one parity chunk, deduplicating the plurality of data chunks to obtain a plurality of deduplicated data chunks, generating storage metadata associated with the plurality of deduplicated data chunks and the at least one parity chunk, generating an object entry associated with the plurality of deduplicated data chunks and the at least one parity chunk, storing the storage metadata and the object entry in an accelerator pool, storing, across a plurality of fault domains, the plurality of deduplicated data chunks and the at least one parity chunk, and initiating metadata distribution on the storage metadata and the object entry across the plurality of fault domains. | 2021-02-04 |
| 20210034473 | DISTRIBUTED FRAMEWORK FOR TASK SPLITTING AND TASK ASSIGNMENTS IN A CONTENT INDEXING SYSTEM - An improved content indexing (CI) system is disclosed herein. For example, the improved CI system may include a distributed architecture of client computing devices, media agents, a single backup and CI database, and a pool of servers. After a file backup occurs, the backup and CI database may include file metadata indices and other information associated with backed up files. Servers in the pool of servers may, in parallel, query the backup and CI database for a list of files assigned to the respective server that have not been content indexed. The servers may then request a media agent to restore the assigned files from secondary storage and provide the restored files to the servers. The servers may then content index the received restored files. Once the content indexing is complete, the servers can send the content index information to the backup and CI database for storage. | 2021-02-04 |
| 20210034474 | STREAMING DATABASE RECOVERY USING CLUSTER LIVE MOUNTS - A database can be instantly recovered by a cluster mapped to the database. Nodes of the cluster are mapped over channels to directories of the database. Scripts are generated from one or more templates that specify the order and values to be executed to perform a database job, such as database recovery. To recover the database, a template is executed that generates and populates scripts, which are processed on the host of the database to recover the database in a nearly instant manner without transferring data files. | 2021-02-04 |
