Abstract
A storage management program is provided with a function of determining a suspension/continuation of a remote backup based on an operation-at-failure management table, and accomplishes the suspension/continuation of the backup based on the application in which a failure has occurred and the mode of this failure. The storage management program is also provided with a function of computing a change in the quantity of data from the last backup before the occurrence of the failure until the first backup after the occurrence of the failure, and determining the suspension/continuation of the backup, enabling to suspend/continue the backup in line with the operating status of the application.
Claims14
A management which is coupled to a host computer that has an application and a storage system that has a disk device providing a volume used by the application and carries out a backup to the volume, comprising:
- a memory;
- and
- a CPU that executes a program in the memory,
- wherein the memory comprising:
- operation-at-failure management information;
- and
- a storage management program,
- wherein the operation-at-failure management information being information that associates an operation at the time of failure denoting the backup operation with an application identifier, an identifier of the type of failure that has occurred in the application, and the failure type, and
- wherein the CPU executing the storage management program, in a case where there is a failure in the application, receives from the host computer a failure notification that includes the identifier of the failed application and the failure type,
- wherein the CPU executing the storage management program refers the failure notification and the operation-at-failure management information and deciding the operation at the time of failure for the application in which the failure has occurred, and
- wherein the CPU executing the storage management program sends to the storage system a command to execute the decided operation at the time of failure.
