  • Publication number: 20230376386
    Abstract: A data backup server may obtain, for a set of databases that includes a primary database and a set of standby databases configured to be synchronized with the primary database. The data backup server may identify, based on the role information, a data backup group that includes a subset of the databases. In some examples, the first database may be included in the data backup group based on being a primary database, the one or more second databases may be included in the data backup group based at least in part on being standby databases of a first type, and the one or more third databases may be excluded from the data backup group based on being standby databases of a second type. The data backup server may then perform a backup procedure based on generating a snapshot of a database within the data backup group.

  • Patent number: 11513917
    Abstract: 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.

  • Patent number: 11467925
    Abstract: Systems and methods to export a database to a native database recovery, environment are described. The system includes a native database recovery environment that includes a target host. The target host receives file information and script information, over a network, via directories from a backup host. The backup host utilizes foreign snapshot files and foreign incremental files to store the file information in the foreign database recovery environment. The file information includes native snapshot files and native incremental files. The script information includes scripts that are executed by the target host in the native database recovery environment. The target host executes the scripts to mount the directories, open the database, restore the database, recover the database to a point-in-time, and unmount the directories.

  • Patent number: 11461122
    Abstract: A database can be instantly cloned from a source device to a target device by a cluster mapped to a database to be cloned. 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 cloning the database to the target device using the mappings. To clone the database, a template can be executed that generates and populates scripts, which can be executed on the target device to provide a functioning cloned database using the mapped cluster.

  • Publication number: 20220276937
    Abstract: Systems and methods for an extended recovery of an exported database are described. The method includes communicating a database from a source host operating in a native database recovery environment, the database being communicated to a backup host operating in a foreign database recovery environment, the native database recovery environment including native snapshot files and native incremental files for storing the database, the foreign database recovery environment including foreign snapshot files and foreign incremental files for storing the database. The method further includes receiving file information and script information, at the source host, the file information including the native snapshot files and the native incremental files, the script to perform operations for causing a recovering of the database in the foreign database recovery environment based on the changes to the database in the foreign database recovery environment after the point-in-time.

  • Patent number: 11360860
    Abstract: Systems and methods to export a database from a foreign database recovery environment are described. The system includes the foreign database recovery environment that includes a backup host that receives the database from a source host operating in a native database recovery environment. The backup host utilizes foreign snapshot files and foreign incremental files for restoring the database. The backup host receives export information. The export information includes a target host, a point-in-time, and a database name identifying the database for export from the backup host to the target host. The backup host initiates a job that generates script information, creates directories, materializes file information, and communicates the script information and the file information, via the directories, to the target host.

  • Patent number: 10204002
    Abstract: A method, article of manufacture, and apparatus for maintaining a cache index inside a deduplicated storage system is discussed. A determination is made to flush a cache buffer to the cache index, wherein both the cache buffer and the cache index comprise a plurality of cache buckets, wherein the cache buckets are stored on a plurality of logical data blocks. A write is initiated to at least one of the plurality of logical data blocks, wherein the write comprises at least one of the cache buckets. An error is received in response to the write request. The error is stored in a memory on the deduplicated storage system.
