StartBackupJob - AWS Backup


Starts an on-demand backup job for the specified resource.

Request Syntax

PUT /backup-jobs HTTP/1.1 Content-type: application/json { "BackupOptions": { "string" : "string" }, "BackupVaultName": "string", "CompleteWindowMinutes": number, "IamRoleArn": "string", "IdempotencyToken": "string", "Lifecycle": { "DeleteAfterDays": number, "MoveToColdStorageAfterDays": number, "OptInToArchiveForSupportedResources": boolean }, "RecoveryPointTags": { "string" : "string" }, "ResourceArn": "string", "StartWindowMinutes": number }

URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in JSON format.


The backup option for a selected resource. This option is only available for Windows Volume Shadow Copy Service (VSS) backup jobs.

Valid values: Set to "WindowsVSS":"enabled" to enable the WindowsVSS backup option and create a Windows VSS backup. Set to "WindowsVSS""disabled" to create a regular backup. The WindowsVSS option is not enabled by default.

Type: String to string map

Key Pattern: ^[a-zA-Z0-9\-\_\.]{1,50}$

Value Pattern: ^[a-zA-Z0-9\-\_\.]{1,50}$

Required: No


The name of a logical container where backups are stored. Backup vaults are identified by names that are unique to the account used to create them and the AWS Region where they are created.

Type: String

Pattern: ^[a-zA-Z0-9\-\_]{2,50}$

Required: Yes


A value in minutes during which a successfully started backup must complete, or else AWS Backup will cancel the job. This value is optional. This value begins counting down from when the backup was scheduled. It does not add additional time for StartWindowMinutes, or if the backup started later than scheduled.

Like StartWindowMinutes, this parameter has a maximum value of 100 years (52,560,000 minutes).

Type: Long

Required: No


Specifies the IAM role ARN used to create the target recovery point; for example, arn:aws:iam::123456789012:role/S3Access.

Type: String

Required: Yes


A customer-chosen string that you can use to distinguish between otherwise identical calls to StartBackupJob. Retrying a successful request with the same idempotency token results in a success message with no action taken.

Type: String

Required: No


The lifecycle defines when a protected resource is transitioned to cold storage and when it expires. AWS Backup will transition and expire backups automatically according to the lifecycle that you define.

Backups transitioned to cold storage must be stored in cold storage for a minimum of 90 days. Therefore, the “retention” setting must be 90 days greater than the “transition to cold after days” setting. The “transition to cold after days” setting cannot be changed after a backup has been transitioned to cold.

Resource types that can transition to cold storage are listed in the Feature availability by resource table. AWS Backup ignores this expression for other resource types.

This parameter has a maximum value of 100 years (36,500 days).

Type: Lifecycle object

Required: No


The tags to assign to the resources.

Type: String to string map

Required: No


An Amazon Resource Name (ARN) that uniquely identifies a resource. The format of the ARN depends on the resource type.

Type: String

Required: Yes


A value in minutes after a backup is scheduled before a job will be canceled if it doesn't start successfully. This value is optional, and the default is 8 hours. If this value is included, it must be at least 60 minutes to avoid errors.

This parameter has a maximum value of 100 years (52,560,000 minutes).

During the start window, the backup job status remains in CREATED status until it has successfully begun or until the start window time has run out. If within the start window time AWS Backup receives an error that allows the job to be retried, AWS Backup will automatically retry to begin the job at least every 10 minutes until the backup successfully begins (the job status changes to RUNNING) or until the job status changes to EXPIRED (which is expected to occur when the start window time is over).

Type: Long

Required: No

Response Syntax

HTTP/1.1 200 Content-type: application/json { "BackupJobId": "string", "CreationDate": number, "IsParent": boolean, "RecoveryPointArn": "string" }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.


Uniquely identifies a request to AWS Backup to back up a resource.

Type: String


The date and time that a backup job is created, in Unix format and Coordinated Universal Time (UTC). The value of CreationDate is accurate to milliseconds. For example, the value 1516925490.087 represents Friday, January 26, 2018 12:11:30.087 AM.

Type: Timestamp


This is a returned boolean value indicating this is a parent (composite) backup job.

Type: Boolean


Note: This field is only returned for Amazon EFS and Advanced DynamoDB resources.

An ARN that uniquely identifies a recovery point; for example, arn:aws:backup:us-east-1:123456789012:recovery-point:1EB3B5E7-9EB0-435A-A80B-108B488B0D45.
