Method and system for synchronizing backup and cloning schedules
Synchronizing backup and cloning schedules is described. A determination is made whether any session is running disk backup. A determination is made whether a backup file is stored in a file recovery area if no session is running disk backup. A determination is made whether a successful clone copy was created of the backup file if the backup file is stored in the file recovery area. A clone copy of the backup file is created if the successful clone copy was created of the backup file. The clone copy is stored on an external destination node.
1. A system for synchronizing backup and cloning schedules, the system comprising:
a processor-based application executed on a computer and configured to:
determine whether any session is running disk backup for a remotely-located database for a database system by querying a dynamic view of a backup and recovery tool of the database system and determining if the backup and recovery tool of the database system is in process of storing a backup file into a file recovery area;
determine, in response to a determination that no session is running disk backup, whether a backup file for the remotely-located database is stored in a file recovery area and is pending verification of whether the backup file requires cloning by querying a backup catalog view associated with the backup and recovery tool;
determine, in response to a determination that the backup file is stored in the file recovery area and is pending verification of whether the backup file requires cloning, whether a current clone copy of the backup file stored in the file recovery area has been successfully created by comparing a time when the backup file was stored in the file recovery area with a time when a most recent successful clone copy was created of any backup file stored in the file recovery area, the most recent successful clone copy being stored on an external destination node that is external to the database system backed up by the backup file;
create, in response to a determination by the comparison of storage times indicating that the current clone copy was not successfully created of the backup file, the current clone copy of the backup file based on the backup file stored in the file recovery area; and
store the current clone copy on the external destination node.
2. The system of claim 1 , wherein the backup file comprises one of a full backup file and an incremental backup file.
3. The system of claim 1 , wherein the external destination node comprises at least one of an external disk and a tape.
4. The system of claim 1 , wherein the processor-based application is further configured to
receive a request to recover the current clone copy;
recover the current clone copy from the external destination node; and
restore the current clone copy to a database associated with the backup file.
5. The system of claim 1 , wherein the file recovery area resides on a disk.
6. A computer-implemented method for synchronizing backup and cloning schedules, the method comprising:
determining whether any session is running disk backup for a remotely-located database for a database system by querying a dynamic view of a backup and recovery tool of the database system and determining if the backup and recovery tool of the database system is in process of storing a backup file into a file recovery area;
determining, in response to a determination that no session is running disk backup, whether a backup file for the remotely-located database is stored in a file recovery area and is pending verification of whether the backup file requires cloning by querying a backup catalog view associated with the backup and recovery tool;
determining, in response to a determination that the backup file is stored in the file recovery area and is pending verification of whether the backup file requires cloning, whether a current clone copy of the backup file stored in the file recovery area has been successfully created by comparing a time when the backup file was stored in the file recovery area with a time when a most recent successful clone copy was created of any backup file stored in the file recovery area, the most recent successful clone copy being stored on an external destination node that is external to the database system backed up by the backup file;
creating, in response to a determination by the comparison of storage times indicating that the current clone copy was not successfully created of the backup file, the current clone copy of the backup file based on the backup file stored in the file recovery area; and
storing the current clone copy on the external destination node.
7. The method of claim 6 , wherein the backup file comprises one of a full backup file and an incremental backup file.
8. The method of claim 6 , wherein the external destination node comprises at least one of an external disk and a tape.
9. The method of claim 6 , wherein the method further comprises:
receiving a request to recover the current clone copy;
recovering the current clone copy from the external destination node; and
restoring the current clone copy to a database associated with the backup file.
10. The method of claim 6 , wherein the file recovery area resides on a disk.
11. A computer program product, comprising a non-transitory computer-readable medium having a computer-readable program code embodied therein, the computer-readable program code adapted to be executed by one or more processors to implement a method for synchronizing backup and cloning schedules, the method comprising:
determining whether any session is running disk backup for a remotely-located database for a database system by querying a dynamic view of a backup and recovery tool of the database system and determining if the backup and recovery tool of the database system is in process of storing a backup file into a file recovery area;
determining, in response to a determination that no session is running disk backup, whether a backup file for the remotely-located database is stored in a file recovery area and is pending verification of whether the backup file requires cloning by querying a backup catalog view associated with the backup and recovery tool;
determining, in response to a determination that the backup file is stored in the file recovery area and is pending verification of whether the backup file requires cloning, whether a current clone copy of the backup file stored in the file recovery area has been successfully created by comparing a time when the backup file was stored in the file recovery area with a time when a most recent successful clone copy was created of any backup file stored in the file recovery area, the most recent successful clone copy being stored on an external destination node that is external to the database system backed up by the backup file;
creating, in response to a determination by the comparison of storage times indicating that the current clone copy was not successfully created of the backup file, the current clone copy of the backup file based on the backup file stored in the file recovery area; and
storing the current clone copy on the external destination node.
12. The computer program product of claim 11 , wherein the backup file comprises one of a full backup file and an incremental backup file.
13. The computer program product of claim 11 , wherein the external destination node comprises at least one of an external disk and a tape.
14. The computer program product of claim 11 , wherein the method further comprises:
receiving a request to recover the current clone copy;
recovering the current clone copy from the external destination node; and
restoring the current clone copy to a database associated with the backup file.
