  • Publication number: 20250086070
    Abstract: Systems and methods to utilize a tablespace to export to a native database recovery environment are described. The system receives file information and script information at a source host that operates in a native database recovery environment. The file information and the script information are received from a backup host that utilizes foreign snapshot files and foreign incremental files for storing the file information. The file information includes native snapshot files and native incremental files. The script information includes one or more scripts that execute, at the source host, to perform operations comprising: mounting the directories; opening an auxiliary database; restoring a tablespace in the auxiliary database; recovering the tablespace in the auxiliary database based on the native incremental files; exporting the tablespace metadata information from the auxiliary database; recovering the tablespace in the database based on the tablespace metadata information; and unmounting the directories.

  • Patent number: 11604761
    Abstract: Systems and methods for utilizing tablespace to export from a foreign database recovery environment are described. The system includes a backup host that operates in a foreign database recovery environment and receives a database from a source host operating in a native database recovery environment. The backup host receives export information including a tablespace identifier and a point-in-time. The tablespace includes file information for export from the backup host to the source host. A job is initiated on the backup host to generate script information (including logic for execution on the source host to recover the tablespace, at the point-in-time, in the database on the source host), create directories on the backup host, materialize file information including snapshots of the database and incremental changes to the database, and communicate the file information and the script information, via the directories, to the source host.

  • 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: 11194761
    Abstract: Systems and methods to optimize utilization of a tablespace for export from a native database recovery environment are described. The system receives a database from a source host, operating in a native database recovery environment, at a backup host operating in a foreign database recovery environment. The foreign database recovery environment utilizes foreign snapshot files and foreign incremental files for storing the database. The system receives a tablespace identifier that identifies a tablespace and a point-in-time that identifies file information for export from the backup host to the source host. The backup host initiates a job to generate script information; create directories; materialize the file information; utilize an auxiliary database to generate tablespace metadata information; and communicate the tablespace metadata information and the script information and the file information, via the directories, and over a network, to the source host, to enable the source host to recover the tablespace.
