Abstract
A method of disaster recovery testing continues to maintain a data collection and it continues to maintain a backup data collection. The method includes creating a disaster recovery control file based on a standard control file. An instance of the backup data collection is protected. A standard output pool is established for recording changes to the backup data collection occurring under control of the standard control file. A disaster recovery output pool is established for recording changes to the backup data collection occurring under control of the disaster recovery control file. Disaster recovery testing is conducted under control of the disaster recovery control file.
Claims10
For use with a storage system including a first tape cartridge storage facility, a second tape cartridge storage facility, and a virtual tape subsystem, wherein a standard control file contains information for managing the storage system, and wherein the first tape cartridge storage facility maintains a data collection, and the second tape cartridge storage facility maintains a backup data collection, a method of disaster recovery testing with the backup data collection at the second tape cartridge storage facility while continuing to maintain the data collection and to maintain the backup data collection, the method comprising:
- creating a disaster recovery control file based on the standard control file;
- protecting an instance of the backup data collection;
- establishing a standard output pool for recording changes to the backup data collection occurring under control of the standard control file after protecting the instance;
- establishing a disaster recovery output pool for recording changes to the backup data collection occurring under control of the disaster recovery control file after protecting the instance;
- and
- conducting the disaster recovery testing under control of the disaster recovery control file.
A storage system including a first tape cartridge storage facility, a second tape cartridge storage facility, and a virtual tape subsystem, wherein a standard control file contains information for managing the storage system, and wherein the first tape cartridge storage facility maintains a data collection, and the second tape cartridge storage facility maintains a backup data collection, the storage system further including control logic executable to perform a method of disaster recovery testing with the backup data collection at the second tape cartridge storage facility while continuing to maintain the data collection and to maintain the backup data collection, the control logic being programmed to:
- create a disaster recovery control file based on the standard control file;
- protect an instance of the backup data collection;
- establish a standard output pool for recording changes to the backup data collection occurring under control of the standard control file after protecting the instance;
- establish a disaster recovery output pool for recording changes to the backup data collection occurring under control of the disaster recovery control file after protecting the instance;
- and
- conduct the disaster recovery testing under control of the disaster recovery control file.
