Properties

Actions

[Event-based policies only] The actions to be performed when the event-based policy is activated. You can specify only one action per policy.

Required: No

Type: Array of Action

Minimum: 1

Maximum: 1

Update requires: No interruption

CopyTags

[Default policies only] Indicates whether the policy should copy tags from the source resource to the snapshot or AMI. If you do not specify a value, the default is false.

Default: false

Required: No

Type: Boolean

Update requires: No interruption

CreateInterval

[Default policies only] Specifies how often the policy should run and create snapshots or AMIs. The creation frequency can range from 1 to 7 days. If you do not specify a value, the default is 1.

Default: 1

Required: No

Type: Integer

Minimum: 1

Update requires: No interruption

CrossRegionCopyTargets

[Default policies only] Specifies destination Regions for snapshot or AMI copies. You can specify up to 3 destination Regions. If you do not want to create cross-Region copies, omit this parameter.

Required: No

Type: Json

Minimum: 0

Maximum: 3

Update requires: No interruption

EventSource

[Event-based policies only] The event that activates the event-based policy.

Required: No

Type: EventSource

Update requires: No interruption

Exclusions

[Default policies only] Specifies exclusion parameters for volumes or instances for which you do not want to create snapshots or AMIs. The policy will not create snapshots or AMIs for target resources that match any of the specified exclusion parameters.

Required: No

Type: Exclusions

Update requires: No interruption

ExtendDeletion

[Default policies only] Defines the snapshot or AMI retention behavior for the policy if the source volume or instance is deleted, or if the policy enters the error, disabled, or deleted state.

By default (ExtendDeletion=false):

  • If a source resource is deleted, Amazon Data Lifecycle Manager will continue to delete previously created snapshots or AMIs, up to but not including the last one, based on the specified retention period. If you want Amazon Data Lifecycle Manager to delete all snapshots or AMIs, including the last one, specify true.

  • If a policy enters the error, disabled, or deleted state, Amazon Data Lifecycle Manager stops deleting snapshots and AMIs. If you want Amazon Data Lifecycle Manager to continue deleting snapshots or AMIs, including the last one, if the policy enters one of these states, specify true.

If you enable extended deletion (ExtendDeletion=true), you override both default behaviors simultaneously.

If you do not specify a value, the default is false.

Default: false

Required: No

Type: Boolean

Update requires: No interruption

Parameters

[Custom snapshot and AMI policies only] A set of optional parameters for snapshot and AMI lifecycle policies.

Note

If you are modifying a policy that was created or previously modified using the Amazon Data Lifecycle Manager console, then you must include this parameter and specify either the default values or the new values that you require. You can't omit this parameter or set its values to null.

Required: No

Type: Parameters

Update requires: No interruption

PolicyLanguage

The type of policy to create. Specify one of the following:

  • SIMPLIFIED To create a default policy.

  • STANDARD To create a custom policy.

Required: No

Type: String

Allowed values: SIMPLIFIED | STANDARD

Update requires: No interruption

PolicyType

The type of policy. Specify EBS_SNAPSHOT_MANAGEMENT to create a lifecycle policy that manages the lifecycle of Amazon EBS snapshots. Specify IMAGE_MANAGEMENT to create a lifecycle policy that manages the lifecycle of EBS-backed AMIs. Specify EVENT_BASED_POLICY to create an event-based policy that performs specific actions when a defined event occurs in your Amazon Web Services account.

The default is EBS_SNAPSHOT_MANAGEMENT.

Required: No

Type: String

Allowed values: EBS_SNAPSHOT_MANAGEMENT | IMAGE_MANAGEMENT | EVENT_BASED_POLICY

Update requires: No interruption

ResourceLocations

[Custom snapshot and AMI policies only] The location of the resources to backup.

  • If the source resources are located in a Region, specify CLOUD. In this case, the policy targets all resources of the specified type with matching target tags across all Availability Zones in the Region.

  • [Custom snapshot policies only] If the source resources are located in a Local Zone, specify LOCAL_ZONE. In this case, the policy targets all resources of the specified type with matching target tags across all Local Zones in the Region.

  • If the source resources are located on an Outpost in your account, specify OUTPOST. In this case, the policy targets all resources of the specified type with matching target tags across all of the Outposts in your account.

Required: No

Type: Array of String

Minimum: 1

Maximum: 1

Update requires: No interruption

ResourceType

[Default policies only] Specify the type of default policy to create.

  • To create a default policy for EBS snapshots, that creates snapshots of all volumes in the Region that do not have recent backups, specify VOLUME.

  • To create a default policy for EBS-backed AMIs, that creates EBS-backed AMIs from all instances in the Region that do not have recent backups, specify INSTANCE.

Required: No

Type: String

Allowed values: VOLUME | INSTANCE

Update requires: No interruption

ResourceTypes

[Custom snapshot policies only] The target resource type for snapshot and AMI lifecycle policies. Use VOLUME to create snapshots of individual volumes or use INSTANCE to create multi-volume snapshots from the volumes for an instance.

Required: No

Type: Array of String

Minimum: 1

Maximum: 1

Update requires: No interruption

RetainInterval

[Default policies only] Specifies how long the policy should retain snapshots or AMIs before deleting them. The retention period can range from 2 to 14 days, but it must be greater than the creation frequency to ensure that the policy retains at least 1 snapshot or AMI at any given time.
