Using the Snapshot page, snapshots can be taken and restored for the virtual server.
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 function for taking and restoring snapshots is supported if the virtualization software is either VMware or Hyper-V. If the virtualization software is RHEL-KVM, there is no function for taking and restoring snapshots.
Also, there is no function for taking and restoring snapshots for Solaris container management servers.
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 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.
When the configuration is modified after taking the snapshots and those snapshots are restored, the server may be restored to the state before the configuration was modified. It is recommended that new snapshots be taken after the configuration is modified.
Even if a created snapshot is not deleted, contact the System Administrator if it is not displayed in the Snapshort window.
