Abstract

The present invention aims to reduce the amount of backup to be transferred, and reduce the recovery time, in the case of a server device built in a virtual environment. A VM 10 connects a plurality of volumes 21 and 22 , starts up software installed on the volume 21 from the volume 21 , stores DB data in the volume 22 , and acquires snapshots of the volumes 21 and 22 at different intervals for each, thereby backing up the images 31 and 32.

First claim

The invention claimed is:

1. A backup restoration method for a virtual environment, comprising:
connecting to a plurality of volume storages including (i) a first volume storage for a first backup target that changes at a first frequency, wherein the first volume storage includes software, and (ii) a second volume storage for a second backup target that changes at a second frequency, wherein the second volume storage includes database data;
running a virtual machine by starting up the software installed on the first volume storage of the plurality of volume storages; and
backing up the first backup target, as a first image on a remote storage, at a first interval corresponding to the first frequency, and backing up the second backup target, as a second image on the remote storage, at a second interval corresponding to the second frequency;
determining that the first volume storage and the second volume storage failed;
creating, from the first image of the remote storage, a new first volume storage that stores the software;
attaching to the new first volume storage and starting up the software included in the new first volume storage; and
creating, from the second image of the remote storage, a new second volume storage that stores the database data, and attaching to the new second volume storage.

2. The backup restoration method according to claim 1 , further comprising:
transferring images respectively backed up from the plurality of volume storages.

3. The backup restoration method according to claim 1 , wherein the virtual machine operates as a session control server, and data in a database is stored in the second volume storage that is different from the first volume storage on which the software is installed.

4. A backup restoration device configured to perform operations comprising:
connecting to a plurality of volume storages including (i) a first volume storage for a first backup target that changes at a first frequency, wherein the first volume storage includes software, and (ii) a second volume storage for a second backup target that changes at a second frequency, wherein the second volume storage includes database data;
running a virtual machine by starting up the software installed on the first volume storage of the plurality of volume storages; and
backing up the first backup target, as a first image on a remote storage, at a first interval corresponding to the first frequency, and backing up the second backup target, as a second image on the remote storage, at a second interval corresponding to the second frequency;
determining that the first volume storage and the second volume storage failed;
creating, from the first image of the remote storage, a new first volume storage that stores the software;
attaching to the new first volume storage and starting up the software included in the new first volume storage; and
creating, from the second image of the remote storage, a new second volume storage that stores the database data, and attaching to the new second volume storage.

5. The backup restoration device according to claim 4 , wherein the operations further comprise:
transferring images respectively backed up from the plurality of volume storages.

6. The backup restoration device according to claim 4 , wherein the virtual machine operates as a session control server, and data in a database is stored in the second volume storage that is different from the first volume storage on which the software is installed.
