ALIYUN::ECS::Snapshot类型用于创建磁盘快照。

语法

{
  "Type": "ALIYUN::ECS::Snapshot",
  "Properties": {
    "SnapshotName": String,
    "Timeout": Integer,
    "Description": String,
    "DiskId": String,
    "Tags": List,
    "InstantAccess": Boolean,

属性

属性名称 类型 必须 允许更新 描述 约束
DiskId String 是 否 将要创建磁盘快照的磁盘ID。 无
SnapshotName String 否 否 快照的显示名称。 长度为2~128个字符。必须以英文字母或汉字开头，不能以http://和https://开头。可包含英文字母、汉字、数字、半角冒号（:）、下划线（_）或短划线（-）。

为防止和自动快照的名称冲突，不能以auto开头。
Timeout Integer 否 否 创建快照的超时时间。 设置此时间会延长创建资源栈的超时时间。如果快照在指定的时间内没有创建完成，则整个资源栈将创建失败。请根据磁盘的大小，数据的多少，设置合理的超时时间。

取值范围：200~1440。

默认值：200。

单位：分钟。
Description String 否 否 快照的描述。 快照的描述。长度为2~256个字符，不能以http://和https://开头。

默认值：空。
Tags List 否 是 标签。 最多支持添加20个标签。

更多信息，请参见Tags属性。

InstantAccess Boolean 否 否 是否开启快照极速可用功能。 取值：
  • true：开启。仅ESSD云盘支持开启该功能。
  • false（默认值）：关闭。即创建普通快照。
InstantAccessRetentionDays Integer 否 否 设置快照极速可用功能的保留时间，保留时间到期后快照将自动释放。 该参数仅在InstantAccess取值为true时生效。

取值范围：1~65,535。

单位：天。

Tags语法

"Tags": [
  {
    "Key": String,
    "Value": String

Value String 否 否 标签值。 长度为0~128个字符，不能以aliyun和acs:开头，不能包含http://或者https:// 。

返回值

Fn::GetAtt

SnapshotId：快照ID。
