Obtenha o carimbo de data/hora restaurável mais recente para contas de backup contínuo

Artigo
12/16/2024

APLICA-SE A: NoSQL MongoDB Gremlin Tabela

Este artigo descreve como obter o carimbo de data/hora restaurável mais recente para contas com o modo de backup contínuo. Ele explica como obter o tempo restaurável mais recente usando o Azure PowerShell e a CLI do Azure e fornece o formato de solicitação e resposta para os comandos PowerShell e CLI.

Esse recurso é suportado para a API do Azure Cosmos DB para contêineres NoSQL, API para MongoDB, API de tabela e API para gráficos Gremlin.

Importante

Para contas de gravação de várias regiões, o carimbo de data/hora restaurável mais recente é determinado por um carimbo de data/hora de resolução de conflitos (crts).

Contêiner SQL

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>]

Pedido de amostra:

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

Exemplo de resposta (em formato UTC):

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}
