  • Publication number: 20220382643
    Abstract: Described in detail herein are systems and methods for single instancing blocks of data in a data storage system. For example, the data storage system may include multiple computing devices (e.g., client computing devices) that store primary data. The data storage system may also include a secondary storage computing device, a single instance database, and one or more storage devices that store copies of the primary data (e.g., secondary copies, tertiary copies, etc.). The secondary storage computing device receives blocks of data from the computing devices and accesses the single instance database to determine whether the blocks of data are unique (meaning that no instances of the blocks of data are stored on the storage devices). If a block of data is unique, the single instance database stores it on a storage device. If not, the secondary storage computing device can avoid storing the block of data on the storage devices.

  • Publication number: 20220342852
    Abstract: A distributed, deduplicated storage system according to certain embodiments is arranged in a parallel configuration including multiple deduplication nodes. Deduplicated data is distributed across the deduplication nodes. The deduplication nodes can be networked together and communicate with one another according using a light-weight, customized communication scheme (e.g., a scheme based on FTP or HTTP). In some cases, deduplication management information including deduplication signatures and/or other metadata is stored separately from the deduplicated data in deduplication management nodes, improving performance and scalability.

  • Publication number: 20220043712
    Abstract: The disclosed enhancements optimize the use of the live browse cache and pseudo-disk storage areas, improving metadata handling so that it can be used more effectively to speed up live browse and file indexing of backup copies in a data storage management system. The enhancements operate granularly to identify within each extent being backed up smaller sectors that comprise metadata. The disclosed approach pre-fetches the metadata of the backup copy before allowing the file scan of the file indexing and/or the live browse operation to proceed. The backup operation, the file indexing operation, and the live browse operation are enhanced to handle the more granular metadata sectors without changing the granularity of the full extents generated and stored in the backup.

  • Patent number: 11188504
    Abstract: An information management system can manage the removal of data block entries in a deduplicated data store using working copies of the data block entries residing in a local data store of a secondary storage computing device. The system can use the working copies to identify data blocks for removal. Once the deduplication database is updated with the changes to the working copies (e.g., using a transaction based update scheme), the system can query the deduplication database for the database entries identified for removal. Once identified, the system can remove the database entries identified for pruning and/or the corresponding deduplication data blocks from secondary storage.

  • Patent number: 11169888
    Abstract: A storage system according to certain embodiments includes a client-side repository (CSR). The CSR may communicate with a client at a higher data transfer rate than the rate used for communication between the client and secondary storage. During copy operations, for instance, some or all of the data being backed up or otherwise copied to secondary storage is stored in the CSR. During restore operations, copies of the data stored in the CSR is accessed from the CSR instead of from secondary storage, improving performance. Remaining data blocks not stored in the CSR can be restored from secondary storage.

  • Publication number: 20210326214
    Abstract: The data storage system according to certain aspects can implement partial file restore, where only a portion of the secondary copy of a file is restored. Such portion may be designated by one or more application offsets for the file. The system may provide an in-chunk index that includes mapping information between the application offsets and the secondary copy offsets. Chunks may refer to logical data units in which secondary copies are stored, and the in-chunk index for a chunk may be stored in secondary storage with the chunk. Because the mapping information may not be provided at a fixed interval, the system can search through application offsets in the in-chunk index to locate the secondary copy offset corresponding to the portion application offset(s). In this manner, the system may restore the designated portion of the secondary copy in a fast and efficient manner by using the in-chunk index.

  • Publication number: 20210271758
    Abstract: This application relates to ransomware detection and data pruning management. Ransomware typically involves an I/O heavy process of encrypting data files and/or deleting or renaming the original files. Thus, ransomware attacks may be detected by analyzing the I/O activity in a given file system. In some embodiments, a software module running on a client machine manages copying, archiving, migrating, and/or replicating of primary data and restoring and/or pruning secondary data (e.g., backup copies of the primary data). When a potential ransomware attack is detected, the software module is immediately stopped so that the software module does not prune any data that may need to be restored. Upon receiving user input that indicates that the client machine is not under a ransomware attack, the software module is allowed to resume its operations, including pruning of the secondary data.
