2. Restoration

Use Flow
STEP 1. Precheck
  • Check the information on the network setting. When using vFirewall or vLoad Balancer and a virtual server in operation that you would like to restore is registered with the settings shown below, cancel the settings temporarily for restoration.

Target Setting Item
vFirewall IP address group, filter rule, NAT/NAPT rule, route
vLoad Balancer Real server, group, route
VPN Connection (compatible with the Customer Portal) Routing


  • Restoration data is overwritten on the target virtual server. Since it is necessary to delete a virtual server from network appliance settings for the sake of system processing, you are asked to check and make settings in advance.
STEP 2. Executing a restoration
  • Execute a restoration at the Customer Portal. See “Executing a Restoration” (on page ).
STEP 3. Checking the completion of a restoration
  • A restoration is completed in about 30 minutes from the status “Successful” in the reception of an email message about the completion of a restoration (if you have made a setting to receive email messages) or in the backup report at the Customer Portal.

STEP 4. Starting operation
  • Push the PowerOn button on the operation screen of the virtual server. Do not push any other button but this one. When you push the PowerOn button for the first time, a guest OS customization is executed, which continues about 30 minutes. During this period, do not operate the virtual server and do not check the operation of a guest OS.
