For automatically applying update to snapshots of a virtual machine (VM), a cloned virtual machine is created reproducing a state of an existing first snapshot of a virtual machine, a first virtual NIC in the cloned VM is disabled, an update is applied to the cloned VM to which a second virtual NIC has been added, the second virtual NIC is deleted from the cloned VM to which the update has been applied, the first virtual NIC is enabled, and a second snapshot of the cloned VM is generated with the enabled first virtual NIC wherein the second snapshot is associated with the virtual machine.

Applying update to snapshots of virtual machine

A technique to execute a backup process efficiently when an identical file is owned by multiple persons in order to decrease storage capacity and traffic volume requirements. In a backup system including a backup execution terminal, backup destination terminals, and a management server, the backup execution terminal executes a deemed backup process for deeming the file identical to the target file and owned on the backup destination terminals to be a backup duplicate of the target file, or an actual backup process for sending the target file to the management server, each of the backup destination terminals stores the backup execution terminal and the file identical to the target file in association with each other at the time of the deemed backup, and the management server stores the target file sent from the backup execution terminal at the time of the actual backup.

Executing a file backup process

A technique to enable the user of storage clouds to use of a plurality of storage clouds without the user of storage clouds being aware of which data is being entrusted to which storage cloud and without sacrificing safety or ease-of-use by selecting at least one storage cloud to store an entity file storable in a cloud-utilizing terminal from among a plurality of storage clouds connected via a network to the cloud-utilizing terminal. This technique includes referencing the attributes or context of an entity file, or the attributes of a virtual folder and each attribute of a plurality of storage clouds, in response to the creation or update of the entity file in the virtual folder in the cloud-utilizing terminal, and selecting at least one storage cloud from among a plurality of storage clouds for storing the entity file so as to satisfy predefined rules.

Selecting storage cloud for storage of entity files from plurality of storage clouds

Configuration information and a system log are acquired for each of virtual servers running on an external computer, and the acquired system logs are analyzed. Relation information on the relation between the acquired configuration information and a configuration item indicating an existing snapshot, which is acquired from the same virtual server and stored, is extracted on the basis of the analysis result. Identification information for identifying the acquired configuration information is generated on the basis of the extracted relation information, and the acquired configuration information and system log are stored as a configuration item indicating a snapshot in association with the generated identification information.
