継続的バックアップアカウントの最新の復元可能タイムスタンプを取得する

[アーティクル]
08/15/2024

適用対象: NoSQL MongoDB Gremlin Table

この記事では、継続的バックアップモードでアカウントの最新の復元可能タイムスタンプを取得する方法について説明します。 Azure PowerShell と Azure CLI を使用して復元可能な最新の時刻を取得する方法を説明し、PowerShell コマンドと CLI コマンドの要求と応答の形式を示します。

この機能は、Azure Cosmos DB API for NoSQL コンテナー、MongoDB 用 API、Table API、Gremlin グラフ用 API でサポートされています。

重要

複数リージョン書き込みアカウントの場合、最新の復元可能なタイムスタンプは、競合解決タイムスタンプ (crts)によって決定されます。これは、以下に示すメソッドからは返されません。 Azure Cosmos DB の変更フィードを使用し、コンテナーに ConflictResolvedTimestamp(crts) を含むドキュメントを返す方法については、こちらの GitHub サンプルを参照してください。

SQL コンテナー

PowerShell

Get-AzCosmosDBSqlContainerBackupInformation -AccountName <System.String> `
  -DatabaseName <System.String> `
  [-DefaultProfile <Microsoft.Azure.Commands.Common.Authentication.Abstractions.Core.IAzureContextContainer>] `
  -Location <System.String> `
  -Name <System.String> `
  -ResourceGroupName <System.String> [<CommonParameters>]

要求のサンプル:

Get-AzCosmosDBSqlContainerBackupInformation -ResourceGroupName "rg" `
  -AccountName "sqlpitracc" `
  -DatabaseName "db1" `
  -Name "container1" `
  -Location "eastus"

応答の例 (UTC 形式):

LatestRestorableTimestamp
-------------------------
10/26/2021 6:24:25 PM

CLI

az cosmosdb sql retrieve-latest-backup-time -g {resourcegroup} \
  -a {accountname} \
  -d {db_name} \
  -c {container_name} \
  -l {location}

要求のサンプル:
