Dapatkan stempel waktu terbaru yang dapat dipulihkan untuk akun cadangan berkelanjutan

Artikel
08/15/2024

BERLAKU UNTUK: NoSQL MongoDB Gremlin Meja

Pelajari cara mendapatkan stempel waktu terbaru yang dapat dipulihkan untuk akun yang diaktifkan dengan mode pencadangan berkelanjutan. Ini menjelaskan cara mendapatkan waktu terbaru yang dapat dipulihkan menggunakan Azure PowerShell dan Azure CLI, dan menyediakan format permintaan dan respons untuk perintah PowerShell dan CLI.

Fitur ini didukung untuk AZURE Cosmos DB API untuk kontainer NoSQL, API untuk MongoDB, Table API, dan API untuk grafik Gremlin.

Penting

Untuk akun tulis multi-wilayah, tanda waktu terbaru yang dapat di-restorable ditentukan oleh tanda waktu resolusi konflik (crts). Ini tidak dikembalikan oleh metode yang tercantum di bawah ini. Lihat sampel GitHub di sini untuk mempelajari cara menggunakan Umpan Perubahan Azure Cosmos DB dan mengembalikan dokumen dengan ConflictResolvedTimestamp(crts) dalam kontainer.

Kontainer 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>]

Permintaan sampel:

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

Respons sampel (dalam format 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}

Permintaan sampel:

az cosmosdb sql retrieve-latest-backup-time -g "rg" \
  -a "sqlpitracc" \
