Function

This API is used to create a full-ECS image from an ECS, Cloud Server Backup Service (CSBS) backup, or Cloud Backup and Recovery (CBR) backup. The API is an asynchronous one. If it is successfully called, the cloud system receives the request to create a full-ECS image. However, you need to use the asynchronous job query API to query the image creation status. For details, see Querying the Status of an Asynchronous Job.

Constraints (Creating a Full-ECS Image from an ECS)

When creating a full-ECS image from an ECS, ensure that the ECS has been properly configured, or the image creation may fail.
A Windows ECS used to create a full-ECS image cannot have a spanned volume, or data may be lost when ECSs are created from that image.
A Linux ECS used to create a full-ECS image cannot have a physical disk group or a logical disk that contains multiple physical disks, or data may be lost when ECSs are created from that image.
A full-ECS image cannot be exported or replicated.
When creating a full-ECS image from a Windows ECS, you need to set the SAN policy of the ECS to OnlineAll. Otherwise, EVS disks attached to the ECSs created from the image may be offline. For details, see "Creating a Full-ECS Image from an ECS" > "Setting the ECS SAN Policy to OnlineAll" in Image Management Service User Guide.

Constraints (Creating a Full-ECS Image from a CSBS Backup)

When creating a full-ECS image from a CSBS backup, ensure that the source ECS of the CSBS backup has been properly configured, or the image creation may fail.
If an ECS is in Stopped state, do not start it when you are using it to create a full-ECS image.
A CSBS backup used to create a full-ECS image cannot have shared disks.
Only an available CSBS backup can be used to create a full-ECS image. A CSBS backup can be used to create only one full-ECS image.
A full-ECS image cannot be exported or replicated.

Constraints (Creating a Full-ECS Image from a CBR Backup)

When creating a full-ECS image from a CBR backup, ensure that the source ECS of the CBR backup has been properly configured, or the image creation may fail.
A CBR backup can be used to create only one full-ECS image.
If an ECS is in Stopped state, do not start it when you are using it to create a full-ECS image.
A full-ECS image created from a CBR backup can be shared with other tenants. However, if it is a shared CBR backup, the full-ECS image created from it cannot be shared.
A full-ECS image cannot be exported or replicated.

Request

Parameters for creating a full-ECS image using an ECS

Parameter	Mandatory	Type	Description
name	Yes	String	Specifies the image name. For detailed description, see Image Attributes.
description	No	String	Provides supplementary information about the image. For detailed description, see Image Attributes.
tags	No	Array of strings	Lists the image tags. This parameter is left blank by default. Use either tags or image_tags.
image_tags	No	Array of objects	Lists the image tags. This parameter is left blank by default. Use either tags or image_tags. For details about image_tags, see Table 1.
instance_id	Yes	String	Specifies the ECS ID. This parameter is required when an ECS is used to create a full-ECS image. To obtain the ECS ID, perform the following operations: Log in to the management console. Under Computing, click Elastic Cloud Server. In the ECS list, click the name of the ECS and view its ID.
enterprise_project_id	No	String	Specifies the enterprise project that the image belongs to. If the value is 0 or left blank, the image belongs to the default enterprise project. If the value is a UUID, the image belongs to the enterprise project corresponding to the UUID. For more information about enterprise projects and how to obtain enterprise project IDs, see Enterprise Management User Guide.
max_ram	No	Integer	Specifies the maximum memory of the image in the unit of MB. This parameter is not configured by default.
min_ram	No	Integer	Specifies the minimum memory of the image in the unit of MB. The default value is 0.
vault_id	No	String	Specifies the ID of the vault to which an ECS is to be added or has been added. To create a full-ECS image from an ECS, create a backup from the ECS and then use the backup to create a full-ECS image. If a CBR backup is created, vault_id is mandatory. If a CSBS backup is created, vault_id is optional. You can obtain the vault ID from the CBR console or section "Querying the Vault List" in Cloud Backup and Recovery API Reference.

Parameters in the request body when a CSBS backup or CBR backup is used to create a full-ECS image

Parameter	Mandatory	Type	Description
name	Yes	String	Specifies the image name. For detailed description, see Image Attributes.
description	No	String	Provides supplementary information about the image. For detailed description, see Image Attributes.
tags	No	Array of strings	Lists the image tags. This parameter is left blank by default. Use either tags or image_tags.
image_tags	No	Array of objects	Lists the image tags. This parameter is left blank by default. Use either tags or image_tags. For details about image_tags, see Table 1.
backup_id	Yes	String	Specifies the CSBS backup ID or CBR backup ID. To obtain the CSBS backup ID, perform the following operations: Log in to the management console. Under Storage, click Cloud Server Backup Service. In the backup list, expand details of the backup to obtain its ID. To obtain the CBR backup ID, perform the following operations: Log in to the management console. Under Storage, click Cloud Backup and Recovery. On the displayed Cloud Server Backup page, click the Backups tab and obtain the backup ID from the backup list.
enterprise_project_id	No	String	Specifies the enterprise project that the image belongs to. If the value is 0 or left blank, the image belongs to the default enterprise project. If the value is a UUID, the image belongs to the enterprise project corresponding to the UUID. For more information about enterprise projects and how to obtain enterprise project IDs, see Enterprise Management User Guide.
max_ram	No	Integer	Specifies the maximum memory of the image in the unit of MB. This parameter is not configured by default.
min_ram	No	Integer	Specifies the minimum memory of the image in the unit of MB. The default value is 0, indicating that the memory is not restricted.
whole_image_type	No	String	Specifies the method of creating a full-ECS image. If a CBR backup is used to create a full-ECS image, this parameter is mandatory and the value must be CBR. In this case, backup_id is the CBR backup ID. If a CSBS backup is used to create a full-ECS image, this parameter can be left blank and the default value CSBS will be used. In this case, backup_id is the CSBS backup ID.

**Table 1** Data structure of the image_tags field
Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the tag key.
value	Yes	String	Specifies the tag value.
