                • Interval (integer) –

                  The period after which to deprecate the cross-Region AMI copies. The period must be less than or equal to the cross-Region AMI copy retention period, and it can’t be greater than 10 years. This is equivalent to 120 months, 520 weeks, or 3650 days.

              If the schedule has a count-based retention rule, this parameter specifies the number of oldest AMIs to deprecate. The count must be less than or equal to the schedule’s retention count, and it can’t be greater than 1000.

            • Interval (integer) –

              If the schedule has an age-based retention rule, this parameter specifies the period after which to deprecate AMIs created by the schedule. The period must be less than or equal to the schedule’s retention period, and it can’t be greater than 10 years. This is equivalent to 120 months, 520 weeks, or 3650 days.

            • IntervalUnit (string) –

              The unit of time in which to measure the Interval.

          • ArchiveRule (dict) –

            [Snapshot policies that target volumes only] The snapshot archiving rule for the schedule. When you specify an archiving rule, snapshots are automatically moved from the standard tier to the archive tier once the schedule’s retention threshold is met. Snapshots are then retained in the archive tier for the archive retention period that you specify.

            For more information about using snapshot archiving, see Considerations for snapshot lifecycle policies.

            • RetainRule (dict) –

              Information about the retention period for the snapshot archiving rule.

              • RetentionArchiveTier (dict) –

                Information about retention period in the Amazon EBS Snapshots Archive. For more information, see Archive Amazon EBS snapshots.

                • Count (integer) –

                  The maximum number of snapshots to retain in the archive storage tier for each volume. The count must ensure that each snapshot remains in the archive tier for at least 90 days. For example, if the schedule creates snapshots every 30 days, you must specify a count of 3 or more to ensure that each snapshot is archived for at least 90 days.

                • Interval (integer) –

                  Specifies the period of time to retain snapshots in the archive tier. After this period expires, the snapshot is permanently deleted.

                • IntervalUnit (string) –

                  The unit of time in which to measure the Interval. For example, to retain a snapshots in the archive tier for 6 months, specify Interval=6 and IntervalUnit=MONTHS.

      • Parameters (dict) –

        [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.

        • ExcludeBootVolume (boolean) –

          [Snapshot policies that target instances only] Indicates whether to exclude the root volume from multi-volume snapshot sets. The default is false. If you specify true, then the root volumes attached to targeted instances will be excluded from the multi-volume snapshot sets created by the policy.

        • NoReboot (boolean) –

          [AMI policies only] Indicates whether targeted instances are rebooted when the lifecycle policy runs. true indicates that targeted instances are not rebooted when the policy runs. false indicates that target instances are rebooted when the policy runs. The default is true (instances are not rebooted).

        • ExcludeDataVolumeTags (list) –

          [Snapshot policies that target instances only] The tags used to identify data (non-root) volumes to exclude from multi-volume snapshot sets.

          If you create a snapshot lifecycle policy that targets instances and you specify tags for this parameter, then data volumes with the specified tags that are attached to targeted instances will be excluded from the multi-volume snapshot sets created by the policy.

          • (dict) –

            Specifies a tag for a resource.

            • Key (string) –

              The tag key.

            • Value (string) –

              The tag value.

      • EventSource (dict) –

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

        • Type (string) –

          The source of the event. Currently only managed CloudWatch Events rules are supported.

        • Parameters (dict) –

          Information about the event.

          • EventType (string) –

            The type of event. Currently, only snapshot sharing events are supported.

          • SnapshotOwner (list) –

            The IDs of the Amazon Web Services accounts that can trigger policy by sharing snapshots with your account. The policy only runs if one of the specified Amazon Web Services accounts shares a snapshot with your account.

            • (string) –

          • DescriptionRegex (string) –

            The snapshot description that can trigger the policy. The description pattern is specified using a regular expression. The policy runs only if a snapshot with a description that matches the specified pattern is shared with your account.

            For example, specifying ^.*Created for policy: policy-1234567890abcdef0.*$ configures the policy to run only if snapshots created by policy policy-1234567890abcdef0 are shared with your account.

      • Actions (list) –

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

        • (dict) –

          [Event-based policies only] Specifies an action for an event-based policy.

              Note

                The target Region.

              • EncryptionConfiguration (dict) –

                • Encrypted (boolean) –

                  To encrypt a copy of an unencrypted snapshot when encryption by default is not enabled, enable encryption using this parameter. Copies of encrypted snapshots are encrypted, even if this parameter is false or when encryption by default is not enabled.

                • CmkArn (string) –

                  The Amazon Resource Name (ARN) of the KMS key to use for EBS encryption. If this parameter is not specified, the default KMS key for the account is used.
