Ottenere il timestamp ripristinabile più recente per gli account con backup continuo

Articolo
08/15/2024

SI APPLICA A: NoSQL MongoDB Gremlin Tabella

Questo articolo illustra come ottenere il timestamp ripristinabile più recente per gli account abilitati con la modalità di backup continuo. Illustra come ottenere il tempo ripristinabile più recente usando Azure PowerShell e l'interfaccia della riga di comando di Azure e fornisce il formato di richiesta e risposta per i comandi di PowerShell e dell'interfaccia della riga di comando.

Questa funzionalità è supportata per l'API Azure Cosmos DB per i contenitori NoSQL, l'API per MongoDB, l'API Table e l'API per i grafici Gremlin.

Importante

Per gli account di scrittura in più aree, il timestamp ripristinabile più recente è scoraggiato da un timestamp di risoluzione dei conflitti (crts). Questo non viene restituito dai metodi elencati di seguito. Vedere l'esempio di GitHub qui per informazioni su come usare il feed di modifiche di Azure Cosmos DB e restituire documenti con ConflictResolvedTimestamp(crts) in un contenitore.

Contenitore 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>]

Richiesta di esempio:

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

Risposta di esempio (in 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}

Richiesta di esempio:

az cosmosdb sql retrieve-latest-backup-time -g "rg" \
  -a "sqlpitracc" \
  -d "db1" \
  -c "container1" \
  -l "eastus"

Risposta di esempio (in formato UTC):

{
  "continuousBackupInformation": {
    "latestRestorableTimestamp": "10/26/2021 5:27:45 PM"
  }
}

Database SQL

Usare lo script seguente per ottenere il timestamp ripristinabile più recente per un database. Questo script esegue l'iterazione di tutti i contenitori all'interno del database specificato e restituisce il timestamp minimo ripristinabile più recente di tutti i contenitori.

Function Get-LatestRestorableTimestampForSqlDatabase {
[CmdletBinding()]
param(
  [Parameter(Position = 0, mandatory = $true)]
  [string] $resourceGroupName,
  [Parameter(Position = 1, mandatory = $true)]
  [string] $accountName,
  [Parameter(Position = 2, mandatory = $true)]
  [string] $databaseName,
  [Parameter(Position = 3, mandatory = $true)]
  [string] $location)

Write-Host "Latest restorable timestamp for a database is minimum of restorable timestamps of all the underlying containers"
Write-Host

Write-Debug "Listing all containers in database: $databaseName"
$containers = Get-AzCosmosDBSqlContainer -ResourceGroupName $resourceGroupName -AccountName $accountName -DatabaseName $databaseName

If (-Not $containers) {

}

Write-Debug "Found $($containers.Length) containers under database $databaseName"

$latestRestorableTimestampForDatabase = [DateTime]::MaxValue
foreach ($container in $containers) {
    Write-Debug "Getting latest restorable timestamp for container: $($container.Name)"

    $latestRestorableTimestampForContainer = Get-AzCosmosDBSqlContainerBackupInformation -ResourceGroupName $resourceGroupName -AccountName $accountName -DatabaseName $databaseName -Name $container.Name -Location $location

    Write-Debug "Latest Restorable Timestamp for container $($container.Name): $($latestRestorableTimestampForContainer.LatestRestorableTimestamp)"

    $latestRestorableTimestampForContainerDateTime = [DateTime]$latestRestorableTimestampForContainer.LatestRestorableTimestamp

    If ($latestRestorableTimestampForContainerDateTime -lt $latestRestorableTimestampForDatabase) {
        Write-Debug "Latest Restorable Timestamp for container $($container.Name) is less than current database restorable timestamp: $latestRestorableTimestampForDatabase"

    throw "Error: Failed to retrieve latest backup timestamp for database: $databaseName"
}

Write-Debug "Latest Restorable Timestamp in UTC for database $($databaseName): $latestRestorableTimestampForDatabase"
