BACKUP MANAGEMENT METHOD
First Claim
1. A storage system comprising a management computer, a host computer and a storage device, whereinthe host computer provides a first virtual machine and a second virtual machine to the host computer;
- the host computer, based on an instruction from the management computer, creates a first snapshot file of the first virtual machine at a first time specified by the management computer, and stores the first snapshot file in a first logical volume of the storage device;
the storage device, based on an instruction from the management computer, replicates in a second logical volume of the storage system the first logical volume;
the management computer manages the first time in association with the first virtual machine snapshot file as the first snapshot file creation time; and
the management computer, in a case where the host computer creates a second snapshot file of the second virtual machine at a second time that is before the first time and stores the second snapshot file in the first logical volume, manages the second snapshot file creation time and a snapshot file of the second virtual machine in association with the first snapshot file creation time and a snapshot file of the first virtual machine.

Abstract
Restoration of all virtual machines are managed in respect of each restoration time thereof in a case where virtual machines at certain time in the past are restored under a server virtualization environment in which a plurality of virtual machines are constituted. A host computer creates a first snapshot of a first virtual machine at a first time specified by a management computer, and stores the first snapshot in a first logical volume of a storage device. Next, the storage system replicates in a second logical volume the first logical volume. In a case where the host computer creates a second snapshot of a second virtual machine at a second time that is before the first time and stores the second snapshot in the first logical volume, the management computer manages or displays the second snapshot creation time and snapshot information in association with the first snapshot creation time and snapshot information, respectively.

6. A management computer which is connected to a host computer that constitutes a first virtual machine and a second virtual machine, and is connected to a storage device having a first logical volume and a second logical volume, wherein
the management computer, in order to restore the first virtual machine at a first time specified by the management computer, instructs the host computer to create a first snapshot file of the first virtual machine at the first time, and to store the first snapshot file in the second logical volume of the storage device; -
the management computer instructs the storage device to replicate in the second logical volume of the storage device the first logical volume; the management computer manages the first time in association with the first virtual machine snapshot file as the first snapshot file time; and the management computer, in a case where the host computer creates a second snapshot file of the second virtual machine at a second time that is before the first time and stores the second snapshot file in the first logical volume, manages the second snapshot file creation time and the second virtual machine snapshot file in association with the first snapshot file creation time and the first virtual machine snapshot file. - View Dependent Claims (7, 8, 9, 10)

11. A backup management method for a first virtual machine constituting to a host computer in a storage system comprising a management computer, the host computer and a storage device, wherein
the host computer, based on an instruction from the management computer, creates a first snapshot file of a first virtual machine at a first time specified by the management computer, and stores the first snapshot file in a first logical volume of the storage device; -
the storage device, based on an instruction from the management computer, replicates in a second logical volume of the storage system the first logical volume; the management computer manages the first time in association with the first virtual machine snapshot file as the first snapshot file creation time; and the management computer, in a case where the host computer creates a second snapshot file of a second virtual machine, which is constituted to the host computer, at a second time that is before the first time, and stores the second snapshot file in the first logical volume, manages the second snapshot file creation time and a snapshot file of the second virtual machine in association with the first snapshot file creation time and a snapshot file of the first virtual machine. - View Dependent Claims (12, 13, 14, 15)
