De meest recente herstelbare tijdstempel voor continue back-upaccounts ophalen

Artikel
04/25/2024

VAN TOEPASSING OP: Nosql MongoDB Gremlin Tabel

In dit artikel wordt beschreven hoe u de meest recente herstelbare tijdstempel voor accounts met continue back-upmodus kunt ophalen. In dit artikel wordt uitgelegd hoe u de meest recente tijd krijgt die kan worden toegepast met behulp van Azure PowerShell en Azure CLI, en hoe u de aanvraag- en antwoordindeling voor de PowerShell- en CLI-opdrachten krijgt.

Deze functie wordt ondersteund voor Azure Cosmos DB-API voor NoSQL-containers, API voor MongoDB, Table-API en API voor Gremlin-grafieken.

Belangrijk

Voor schrijfaccounts voor meerdere regio's wordt de meest recente restorable timestamp bepaald door een tijdstempel voor conflictoplossing (crts). Dit wordt niet geretourneerd door de onderstaande methoden. Zie hier het GitHub-voorbeeld voor meer informatie over het gebruik van de wijzigingenfeed van Azure Cosmos DB en het retourneren van documenten in ConflictResolvedTimestamp(crts) een container.

SQL-container

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>]

Voorbeeldaanvraag:

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

SQL-database

Gebruik het volgende script om de meest recente tijdstempel voor een database op te halen. Dit script doorloopt alle containers in de opgegeven database en retourneert het minimale tijdstempel van de meest recente restorable tijdstempel van alle containers.

Function Get-LatestRestorableTimestampForSqlDatabase {

  [Parameter(Position = 0, mandatory = $true)]
  [string] $resourceGroupName,

  [string] $databaseName,
  [Parameter(Position = 3, mandatory = $true)]
  [string] $location)
