# AWS::SSMIncidents::ReplicationSet
<a name="aws-resource-ssmincidents-replicationset"></a>

The `AWS::SSMIncidents::ReplicationSet` resource specifies a set of Amazon Web Services Regions that Incident Manager data is replicated to and the Amazon Key Management Service (Amazon KMS key used to encrypt the data.

## Syntax
<a name="aws-resource-ssmincidents-replicationset-syntax"></a>

To declare this entity in your Amazon CloudFormation template, use the following syntax:

### JSON
<a name="aws-resource-ssmincidents-replicationset-syntax.json"></a>

```
{
  "Type" : "AWS::SSMIncidents::ReplicationSet",
  "Properties" : {
      "[DeletionProtected](#cfn-ssmincidents-replicationset-deletionprotected)" : Boolean,
      "[Regions](#cfn-ssmincidents-replicationset-regions)" : [ ReplicationRegion, ... ],
      "[Tags](#cfn-ssmincidents-replicationset-tags)" : [ Tag, ... ]
    }
}
```

### YAML
<a name="aws-resource-ssmincidents-replicationset-syntax.yaml"></a>

```
Type: AWS::SSMIncidents::ReplicationSet
Properties:
  [DeletionProtected](#cfn-ssmincidents-replicationset-deletionprotected): Boolean
  [Regions](#cfn-ssmincidents-replicationset-regions): 
    - ReplicationRegion
  [Tags](#cfn-ssmincidents-replicationset-tags): 
    - Tag
```

## Properties
<a name="aws-resource-ssmincidents-replicationset-properties"></a>

`DeletionProtected`  <a name="cfn-ssmincidents-replicationset-deletionprotected"></a>
Determines if the replication set deletion protection is enabled or not. If deletion protection is enabled, you can't delete the last Region in the replication set.  
*Required*: No  
*Type*: Boolean  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Regions`  <a name="cfn-ssmincidents-replicationset-regions"></a>
Specifies the Regions of the replication set.  
*Required*: Yes  
*Type*: Array of [ReplicationRegion](aws-properties-ssmincidents-replicationset-replicationregion.md)  
*Minimum*: `1`  
*Maximum*: `3`  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Tags`  <a name="cfn-ssmincidents-replicationset-tags"></a>
A list of tags to add to the replication set.  
*Required*: No  
*Type*: Array of [Tag](aws-properties-ssmincidents-replicationset-tag.md)  
*Maximum*: `50`  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

## Examples
<a name="aws-resource-ssmincidents-replicationset--examples"></a>

### Create a replication set
<a name="aws-resource-ssmincidents-replicationset--examples--Create_a_replication_set"></a>

The following example creates a replication set.

**Note**  
We recommend creating a replication set and response plan using a single template. For a demonstration, see the examples for [AWS::SSMIncidents::ResponsePlan](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/aws-resource-ssmincidents-responseplan.html#aws-resource-ssmincidents-responseplan--examples).
