US 2012/0072685 A1 · METHOD AND APPARATUS FOR BACKUP OF VIRTUAL MACHINE DATA

Abstract

Embodiments of the invention provide backup of virtual machine data and preferably simplify the backup system, especially in the virtual machine environment that uses an external storage subsystem. A system includes a storage system coupled via a network to a server and a management server. The storage system includes a plurality of storage volumes. The server includes virtual machines running thereon and has virtual machine data stored on the storage volumes. The management server comprises a processor, a memory, and a backup control module, which is configured to detect a virtual machine on the server which is suspended or terminated; identify one or more storage volumes which are used by the detected virtual machine; and direct the storage system to create a backup volume of the determined one or more storage volumes to back up data of the identified one or more storage volumes.

A computer-readable storage medium storing a plurality of instructions for controlling a data processor to control backup of virtual machine data in a system including a storage system coupled via a network to a server and a management server, the storage system including a plurality of storage volumes, the server including a plurality of virtual machines running thereon and having virtual machine data stored on the storage volumes, the plurality of instructions comprising:

instructions that cause the data processor to detect a virtual machine on the server which is suspended or terminated;
instructions that cause the data processor to identify one or more storage volumes which are used by the detected virtual machine;
and
instructions that cause the data processor to direct the storage system to create a backup volume of the determined one or more storage volumes to back up data of the identified one or more storage volumes.
