  • Publication number: 20240143755
    Abstract: Example implementations relate to deduplication operations in a storage system. An example includes receiving data units of a backup stream to be stored in a deduplication storage system; performing a first matching operation to match the data units against a first container index of a plurality of container indexes, where the plurality of container indexes comprise metadata indicating storage locations of data units previously stored in the persistent storage; calculating a first ratio indicating the amount of deduplication that occurred during the first matching operation against the first container index; and in response to a determination that the first ratio violates a condition with respect to local ratio history data of the first container index, identifying at least one portion of the backup stream as being potentially affected by a ransomware attack.

  • Publication number: 20240086098
    Abstract: Example implementations relate to deduplication operations in a storage system. An example includes, in response to initiation of a new backup process to store a first stream of data, initializing a temporary sparse index to be stored in a memory of a deduplication storage system; identifying a cloned portion of the first data stream; identifying at least one container index associated with the cloned portion of the first data stream; identifying a set of hook points included in the at least one container index; and populating the temporary sparse index with a set of entries, the set of entries mapping the identified set of hook points to the at least one container index.

  • Patent number: 11836053
    Abstract: Example implementations relate to metadata operations in a storage system. An example storage system includes a machine-readable storage storing instructions executable by a processor to determine to generate a synthetic full backup based on data stream representations of a plurality of data streams. The instructions are also executable to, in response to a determination to generate the synthetic full backup, create a logical group including the data stream representations. The instructions are also executable to specify a cache resource allocation for the logical group, and generate the synthetic full backup from data stream representations using an amount of a cache resource limited by the cache resource allocation for the logical group.

  • Patent number: 11803483
    Abstract: Example implementations relate to storing manifest portions in a metadata cache. An example includes receiving, by a storage controller, a read request associated with a first data unit. In response to receiving the read request, the storage controller stores a manifest portion in a metadata cache, the stored manifest portion comprising a plurality of records, the plurality of records including a first record associated with the first data unit. The storage controller determines storage information of the first data unit using pointer information included in the first record of the stored manifest portion, and replaces the pointer information in the first record with the determined storage information of the first data unit.

  • Patent number: 11803518
    Abstract: Examples implementations relate to journals for metadata changes. An example includes detecting, by a storage controller, metadata changes associated with a container index of a deduplication storage system; recording, by the storage controller, the detected metadata changes in a journal associated with the container index, where the journal is included in a journal group comprising a plurality of journals; determining, by the storage controller, whether a filled amount of the journal exceeds a fill threshold; and, in response to a determination that the filled amount of the journal does not exceed the fill threshold, writing the journal group from memory to persistent storage.

  • Publication number: 20230259488
    Abstract: Example implementations relate to metadata operations in a storage system. An example includes a machine-readable medium storing instructions that upon execution cause a processor to: receive a data stream to be stored in persistent storage of a deduplication storage system; store data units of the data stream in a container entity group object according to arrival time, where the data units of the container entity group object are referenced by a plurality of container indexes; generate a data index to list each container index that references at least one data unit included in the container entity group object; and in response to a determination that the total size of the container entity group object exceeds the threshold size, transfer the container entity group object from memory to the persistent storage.

  • Publication number: 20230237048
    Abstract: Example implementations relate to metadata operations in a storage system. An example includes detecting, by a storage controller of a deduplication storage system, a housekeeping operation to perform updates to data of a set of container indexes of stored deduplicated data; in response to a detection of the housekeeping operation, the storage controller identifying, among the set of container indexes, a plurality of container indexes associated with a particular journal group, the particular journal group comprising a plurality of journals to store updates to data of the plurality of container indexes, respectively; and maintaining, by the storage controller, the particular journal group loaded in memory until all of the updates of the housekeeping operation to the plurality of container indexes have been stored in the respective journals of the particular journal group.

  • Patent number: 11593021
    Abstract: Example implementations relate to metadata operations in a storage system. An example method includes receiving, from a first stream process, a first write request for a first container index in memory. The method further includes, in response to a receipt of the first write request, sending a first token to the first stream process without writing the first container index to a persistent storage. The method further includes receiving, from a second stream process, a first completion request for the first container index. The method further includes, in response to a receipt of the first completion request, writing the first container index from the memory to the persistent storage.
