Managing Virtual Server for SAP Backup Images

Create a backup image from an existing virtual server for SAP. Also, delete an already created backup image.

When a backup image has been created for a virtual server for SAP, if the system stops operating properly for some reason, it is possible to restore the virtual server for SAP from the backup image.

Tip: When it is necessary to temporarily maintain the status of a system due to updating of an application, etc., use the snapshot function. Backup images should be used when it is necessary to create a regular backup for a system that will be retained for a long time.
Note: This function is only provided in Eastern Japan Region 1 and Western Japan Region 2.

Creating a Backup Image

To create a backup image from a virtual server for SAP that has been created, specify the following items.

Table 1. Creating a Backup Image (List of Items That Can Be Set)
Item Description Required
Name

Specify a name for the backup image. The characters that you specify must meet the following specifications:

  • Specify 32 characters or less using alphanumeric characters and underscores (_)
  • Use an alphabetic character as the first character
  • The name must be unique within the project
 Yes
Type Specify "backup." Yes
Resource ID of Virtual Server for SAP Specify the resource ID of the target virtual server for SAP for which you want to create a backup image Yes
Comment

Specify a comment (character string) to set for the backup image. The characters that you specify must meet the following specifications:

  • Specify double-byte and single-byte characters other than percent signs (%), backslashes (\), double quotation marks ("), and newline characters
  • Specify at least 1 character, and no more than 96 characters
  
Disk Specify whether to back up only the system disk, or to also back up all of the data disks  
Note:
  • As a target for which you want to create a backup image, specify a virtual server for SAP that has been started before.
  • When creating a backup image, stop the target virtual server for SAP in advance.

Re-creating a Virtual Server Using a Backup Image

When a virtual server for SAP stops operating correctly, re-create the virtual server for SAP from a backup image. To re-create a virtual server for SAP, specify the following items.

Important: When a virtual server for SAP has been re-created from a backup image, the re-created virtual server for SAP is considered to be a different virtual server from the one used to create the backup. Be careful, as an additional charge from the OS provision service will be incurred for the re-created virtual server.
Tip: After re-creating a virtual server for SAP from a backup image, delete the original virtual server for SAP that was used as the source for backup image creation. Immediately after a virtual server for SAP is created, it will be in the "stopped" state. Start the virtual server for SAP as necessary.
