VM 还原点的跨区域复制
本文介绍了如何将虚拟机 (VM) 还原点复制到另一个区域。
先决条件
若要跨区域复制还原点，需要在目标区域中预先创建 restorePointCollection 资源。
在复制还原点之前，请详细了解跨区域复制及其限制。
在目标区域中创建还原点集合
将现有 VM 还原点从一个区域复制到另一个区域的第一步是，通过引用源区域的 restorePointCollection 在目标区域中创建 restorePointCollection 资源。
URI 请求
PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/restorePointCollections/{restorePointCollectionName}&api-version={api-version}
请求正文
{
"name": "name of target restorePointCollection resource",
"location": "location of target restorePointCollection resource",
"tags": {
"department": "finance"
},
"properties": {
"source": {
"id": "/subscriptions/{subid}/resourceGroups/{resourceGroupName}/providers/microsoft.compute/restorePointCollections/{restorePointCollectionName}"
}
}
}
响应
请求响应包括状态代码和一组响应头。
状态代码
该操作将在创建期间返回 201，在更新期间返回 200。
响应正文
{
"name": "name of the copied restorePointCollection resource",
"id": "CSM Id of copied restorePointCollection resource",
"type": "Microsoft.Compute/restorePointCollections",
"location": "location of the copied restorePointCollection resource",
"tags": {
"department": "finance"
},
"properties": {
"source": {
"id": "/subscriptions/{subid}/resourceGroups/{resourceGroupName}/providers/microsoft.compute/restorePointCollections/{restorePointCollectionName}",
"location": "location of source RPC"
}
}
}
在目标区域中创建 VM 还原点
下一步是通过引用源区域中需要复制的还原点来触发目标 RestorePointCollection 资源中的还原点复制操作。
URI 请求
PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/restorePointCollections/{restorePointCollectionName}/restorePoints/{restorePointName}&api-version={api-version}
请求正文
{
"name": "name of the restore point resource",
"properties": {
"sourceRestorePoint": {
"id": "/subscriptions/{subid}/resourceGroups/{resourceGroupName}/providers/microsoft.compute/restorePointCollections/{restorePointCollectionName}/restorePoints/{restorePointName}"
}
}
}
注意
sourceRestorePoint 的位置是根据源 RestorePointCollection 中的所在位置推断出来的。
响应
请求响应包括状态代码和一组响应头。
状态代码
此操作的运行时间较长，因此会在创建过程中返回 201。 客户端应使用该操作来进行状态轮询。 为此，提供了 location 和 Azure-AsyncOperation 标头。
在还原点创建过程中，ProvisioningState 在 GET 还原点 API 响应中显示为 Creating。 如果创建失败，ProvisioningState 将显示为 Failed。 启动跨区域的数据复制时，ProvisioningState 将设置为 Succeeded。
注意
你可以通过在目标 VM 还原点上调用 GET 实例视图（?$expand=instanceView）来跟踪复制状态。 有关如何执行此操作的步骤，请参阅“获取 VM 还原点复制状态”部分。仅当所有磁盘还原点的复制都成功时，VM 还原点才被视为可用（可用于还原 VM）。

获取 VM 还原点复制状态
启动 VM 还原点的复制后，可通过在目标 VM 还原点上调用 GET 实例视图 (?$expand=instanceView) 来跟踪复制状态。
