Abstract

A storage unit stores information indicating a backup history of data associated with each of a plurality of virtual machines operating on one or more information processing apparatuses. An operation unit determines an order of migrating each of the plurality of virtual machines to one or more other information processing apparatuses, based on the information indicating the backup history. The operation unit controls the information processing apparatus so as to migrate each of the virtual machines in the order.

Claims

1. An information processing apparatus comprising:

a memory configured to store information indicating a backup history of data associated with each of a plurality of virtual machines operating on one or more apparatuses; and

a processor configured to perform a procedure including determining an order of migrating each of the plurality of virtual machines to one or more other apparatuses, based on the information indicating the backup history, and controlling the one or more apparatuses so as to migrate each of the plurality of virtual machines in the order.

2. The information processing apparatus according to claim 1, wherein the determining includes determining the order, based on a time at which a backup has been performed for each of the plurality of virtual machines.

3. The information processing apparatus according to claim 2, wherein the determining includes determining the order so as to preferentially migrate a virtual machine having a larger time difference between the time at which a backup has been performed and current time.

4. The information processing apparatus according to claim 1, wherein the determining includes determining the order, based on whether a backup performed for each of the plurality of virtual machines has succeeded or failed.

5. The information processing apparatus according to claim 4, wherein the determining includes determining the order so as to preferentially migrate a virtual machine whose backup has failed.

6. The information processing apparatus according to claim 1, wherein the determining includes determining the order, based on information indicating an installation site of a storage device which is a storage destination of data which has been backed up.

7. The information processing apparatus according to claim 6, wherein the determining includes determining the order so as to preferentially migrate a virtual machine whose storage device which is a storage destination of backed up data is installed at a site located in an area which is affected by an influence of a disaster.

8. The information processing apparatus according to claim 1, wherein the determining includes determining the order for a virtual machine operating on an apparatus which is affected by an influence of a disaster, among the one or more apparatuses.

9. The information processing apparatus according to claim 8, wherein the memory stores information indicating an area in which the one or more apparatuses are installed, and

upon reception of information indicating an area which is affected by an influence of a disaster notified from a warning apparatus, the determining includes identifying an apparatus affected by the influence of the disaster, based on the information stored in the memory.

10. The information processing apparatus according to claim 1, wherein

the memory stores information indicating importance of each of the plurality of virtual machines, and

the determining includes determining the order, based on the information indicating the backup history and the information indicating the importance.

11. A non-transitory computer-readable storage medium storing a computer program that causes a computer to perform a procedure comprising:

determining an order of migrating each of a plurality of virtual machines to one or more other apparatuses, based on information indicating backup history of data associated with each of the plurality of virtual machines operating on one or more apparatuses, and

controlling the one or more apparatuses so as to migrate each of the plurality of virtual machines in the order.

12. A virtual machine migration method comprising:

determining, by a processor, an order of migrating each of a plurality of virtual machines to one or more other apparatuses, based on information indicating backup history of data associated with each of the plurality of virtual machines operating on one or more apparatuses, and

controlling, by the processor, the one or more apparatuses so as to migrate each of the plurality of virtual machines in the order.
