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.

Utilizing a tablespace to export to a native database recovery environment

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.

Extended recovery of an exported database

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.

Utilizing a tablespace to export from a foreign database recovery environment

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.

Streaming database recovery using cluster live mounts

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.

Exporting a database to a native database recovery environment

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.

Streaming database cloning using cluster live mounts

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.

Exporting a database from a foreign database recovery environment

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.

Optimizing utilization of a tablespace for exporting from a foreign database recovery environment

A database can be backed up and 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 backup or recovery. To initiate a given database job, a template can be executed that generates and populates scripts, which are processed on the host of the database to perform the database job in a nearly instant manner using the mapped nodes of the cluster.
