Using the [Snapshot] page, snapshots can be taken and restored for the virtual server.
These are supported if the server virtualization software is VMware, Hyper-V, or Citrix XenServer.
If the server virtualization software is Citrix XenServer, the corresponding virtual server must be stopped when taking a snapshot.
To take the restore them, the target virtual server must be inactive.
Snapshot is managed by the generation. Snapshots of older generations will be deleted if snapshots that are older than three generations are to be taken.
Contact the system administrator if it is necessary to take snapshots over 4 or more generations.
Note
The server will enter an error state if an error occurs while taking or restoring snapshots.
When this occurs, a character string "Error" and [x] button will be displayed on the [Snapshot] column of the relevant row on the [Server List] page. To clear the error state, click the [X] button.
The backup products that support the virtual server backup operations located on the server virtualization software must be used to back up the virtual server to a disk or tape device that is not the disk device the virtual server is running on.
NICs cannot be added to or deleted from a server that has snapshots. When adding or deleting NICs, delete all snapshots of the server beforehand.
Even if a created snapshot is not deleted, contact the System Administrator if it is not displayed in the [Snapshot] window.
