Abstract
The active server A101 notifies its own operating status to the administration server 106, and the administration server 106 acquires a snapshot and copies a disk according to the policy established by a user. When the active server A101 or the active disk 113 fails, the administration server 106 chooses a backup server A104 and a status storage disk A114 to be booted and restarts them by using the snapshot according to the policy.
