创建云硬盘快照
功能介绍
创建云硬盘快照。
调用方法
请参见如何调用API。
URI
POST /v2/{project_id}/cloudsnapshots
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
project_id |
是 |
String |
项目ID。 获取方法请参见"获取项目ID"。 |
请求参数
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
X-Auth-Token |
是 |
String |
用户Token。 通过调用IAM服务获取用户Token接口获取(响应消息头中X-Subject-Token的值)。 |
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
snapshot |
是 |
CreateSnapshotOption object |
快照信息。 |
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
volume_id |
是 |
String |
源云硬盘的ID。 |
force |
否 |
Boolean |
强制创快照标示,默认为false。 当force标记为false时,云硬盘处于挂载状态时,不能强制创建快照。 当force标记为true时,即使云硬盘处于挂载状态时,仍可以创建快照。 |
metadata |
否 |
Map<String,String> |
云硬盘快照的元数据信息。 |
description |
否 |
String |
云硬盘快照描述,最大支持85个字符。 最小长度:0 最大长度:255 |
name |
否 |
String |
云硬盘快照名称。最大支持64个字符。 对云硬盘创建备份时,同时会创建以autobk_snapshot_为名称前缀的快照,云硬盘控制台对此类快照会有操作限制。 因此建议不要创建以autobk_snapshot_为名称前缀的快照,避免影响快照的正常使用。 最小长度:0 最大长度:255 |
