  • Patent number: 10896157
    Abstract: In an approach to maintain data integrity in a computer data storage system, a clone management table is generated for a clone file tree that includes a relationship between at least one parent file and a clone file. The parent file is restored by: (i) determining that the parent-child relationship exists between the parent file and the clone file based on an entry in the clone management table, (ii) restoring data blocks in the parent file to the file system based on an analysis of an entry in the clone management table for the parent file and an identification of data blocks included in the clone file, and (iii) generating a new instance of the parent file based on the data blocks included in the file system and the entry in the clone management table for the clone file tree.

  • Patent number: 10795788
    Abstract: A remote data replication method and a storage system, where a production array sends a data replication request to a disaster recovery array. The data replication request includes an identifier of a source object and a data block corresponding to the source object. The data block is stored in physical space of a hard disk of the production array. The disaster recovery array receives the data replication request. The disaster recovery array creates a target object when the disaster recovery array does not include an object having a same identifier as the source object. An identifier of the target object is the same as the identifier of the source object, the disaster recovery array writes the data block into the physical space. This may reduce bandwidth load between the production array and the disaster recovery array.

  • Patent number: 10747732
    Abstract: A virtual database administrator (VDBA) is implemented in a database server network to monitor back-up write events from the database servers on the network to a network back-up server and correct failed back-up attempts. The VDBA regularly polls the database servers for copies of event logs that include information about back-up attempts. The VDBA parses each of the event logs, searching for the back-up log entries indicating successful or failed back-up writes for particular databases. For failed back-up writes, the VDBA instructs the specific database server to retry the back-up write for the particular database. The back-up retry instructions are specific to the database server and cause a back-up retry limited to the particular database on the server that experienced the failure.

  • Patent number: 10101948
    Abstract: Provided are a computer program product, system, and method for an application to provide for, in one embodiment, using hierarchical storage management to respond to a request to delete a data set by migrating the data set to another storage tier in a storage system before deleting the data set from its current location. As a result, the data set is stored on another tier to provide an opportunity to reverse the decision to delete the data set. In one embodiment, a temporary interval of time is provided to reverse the deletion decision and restore the data set from the migrated data set, before the data set is permanently deleted.

  • Patent number: 10083095
    Abstract: Embodiments are described for analytic backup of datasets in a client-server network. A system or processor-based operation derives historical data about backup operations performed in a client-server computer network system and analyzes a present backup operation to be performed for a client computer dataset with respect to a plurality of parameters comprising data type, backup level/data density, backup method, and target storage type. A report comparing one or more past backup operations from the historical data to the present backup operation is generated and transmitted to a user of the client to facilitate selection of an optimum backup method for the present backup operation with respect to minimized backup operation time.

  • Patent number: 10055420
    Abstract: Methods, systems, and apparatus for optimizing a cache memory device of a storage system are described. In one embodiment, a first base segment tree representing a first full backup including data and metadata describing the data is cached in a cache memory device. Subsequently, a plurality of incremental segment trees representing incremental backups to the first full backup are cached in the cache memory device. Each of incremental segment trees corresponding to the changes to the first full backup, without modifying the first base segment tree in response to the changes. At least two of the incremental segment trees are merged into an updated incremental segment tree to reduce a storage space of the cache memory device to store the incremental segment trees. The updated incremental segment tree comprises data and metadata represented by two or more incremental segment trees.

  • Patent number: 10031816
    Abstract: The disclosed computer-implemented method for healing images in deduplication storage may include (i) detecting that a data segment stored within deduplication storage is corrupted by executing an algorithm on the data segment to generate a numerical identifier for the data segment and determining that the numerical identifier does not match a previously stored numerical identifier for the data segment, (ii) checking, during a backup operation, whether a digital fingerprint of a data segment of an image being backed up matches a digital fingerprint of the corrupted data segment that was taken prior to corruption and that is already stored within the deduplication storage, and (iii) appending the data segment from the image being backed up to a container that already contains the corrupted data segment rather than replacing the corrupted data segment. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 10025792
    Abstract: According to one embodiment, a method includes presenting a medium to more than one user as being exclusively occupied by whichever user attempts to access at least one file from the medium, writing a first file managed by a first user to a data partition of the medium, and storing a first user identifier (ID) that identifies the first user as metadata to an index partition of the medium in response to writing the first file managed by the first user. In another embodiment, a method includes reading metadata from an index partition of a medium from a first user of a plurality of users, extracting first file attribute information associated with a first user ID that indicates a first user from the metadata, and reading a first file based on the first file attribute information associated with the first user ID from a data partition of the medium.

  • Patent number: 9913296
    Abstract: The present invention relates to a wireless communication system, and more particularly to a method for enabling a station (STA) to perform a backoff in a wireless LAN system and an apparatus therefor. In a wireless LAN system according to an embodiment of the present invention, a method for enabling a station (STA) to perform a backoff includes the steps of: performing a first backoff procedure at a first primary channel for a transmission of a data unit having a size of a first channel width; performing a second backoff procedure at a second primary channel for a transmission of a data unit having a size equal to or greater than a second channel width; if a transmission opportunity (TXOP) is permitted as a result of the first backoff procedure, transmitting the data unit having a size of the first channel width; and if a TXOP is permitted as a result of the second backoff procedure, transmitting the data unit having a size equal to or greater than the second channel width.

  • Patent number: 9753814
    Abstract: In one example, a method is provided for backing up client data at a datacenter. Initially, an incremental backup is received from a client and stored at the datacenter. Next, a table of contents for the incremental backup is created, and differences identified between the incremental backup and a dataset previously stored at the datacenter. The offsets imposed by any new or modified blocks present in the incremental backup can then be identified and recorded, and used to identify respective data ranges in the incremental backup for any new and modified blocks, which data ranges can then be recorded. Next, a reference block can be created for each block of the previously stored dataset that was not modified in the incremental backup. The reference block can then be stored at the datacenter in association with the incremental backup.
