How do I turn on DynamoDB point-in-time recovery?

2 分的閱讀內容

I want to use point-in-time recovery for Amazon DynamoDB, but I don't know how to turn it on.

Short description

To turn on point-in-time recovery (PITR) for your DynamoDB instance, use one of the following methods:

DynamoDB console
AWS Command Line Interface (AWS CLI)
AWS CloudFormation
DynamoDB API

Note: DynamoDB charges for PITR based on the size of each DynamoDB table, including table data and local secondary indexes. To determine your backup charges, DynamoDB continuously monitors the size of the tables that have PITR turned on. You're billed for PITR usage until you turn off PITR for each table.

Resolution

DynamoDB console

Complete the following steps:

Open the DynamoDB console.
In the navigation pane, choose Tables, and then select your table.
Under Backups, for the Point-in-time recovery (PITR) option, choose Edit.
Select Turn on point-in-time recovery, and then choose Save changes.

AWS CLI

Note: If you receive errors when you run AWS CLI commands, then see Troubleshoot AWS CLI errors. Also, make sure that you're using the most recent AWS CLI version.

Run the update-continuous-backups command with the point-in-time-recovery-specification setting turned on:

aws dynamodb update-continuous-backups \
 --table-name <table-name>\
 --point-in-time-recovery-specification PointInTimeRecoveryEnabled=true

CloudFormation

Use the AWS::DynamoDB::Table resource with the PointInTimeRecoverySpecification property turned on:

Resources:
  iotCatalog:
    Type: AWS::DynamoDB::Table
      Properties:
      ...
      PointInTimeRecoverySpecification:
        PointInTimeRecoveryEnabled: true

DynamoDB API

Run the UpdateContinuousBackups API operation with the PointInTimeRecoverySpecification parameter turned on.

Request syntax example:

{
   "PointInTimeRecoverySpecification": { 
      "PointInTimeRecoveryEnabled": boolean
   },
   "TableName": "string"
}

Response syntax example:

{
   "ContinuousBackupsDescription": { 
      "ContinuousBackupsStatus": "string",
      "PointInTimeRecoveryDescription": { 
         "EarliestRestorableDateTime": number,
         "LatestRestorableDateTime": number,
         "PointInTimeRecoveryStatus": "string"
      }
   }
}
