    Note

    This option moves all the archivable recovery points to the Vault-archive tier.

You can monitor the progress in backup jobs.

You can move all recommended recovery points for selected Azure Virtual Machines to the Vault-archive tier. Learn about recommendation set for Azure Virtual Machine.

Follow these steps:

  1. Select the Virtual Machine whose recovery points you want to move to the Vault-archive tier.

  2. Select click here to view recommended recovery points.

Note

To ensure cost savings, you need to move all the recommended recovery points to the Vault-archive tier. To verify, follow steps 1 and 2. If the list of recovery points is empty in step 3, all the recommended recovery points are moved to the Vault-archive tier.

Restore

To restore the recovery points that are moved to archive, you need to add the required parameters for rehydration duration and rehydration priority.

Get started

  1. Download the latest version of PowerShell from GitHub.

  2. Run the following cmdlet in PowerShell:

    install-module -name Az.RecoveryServices -Repository PSGallery -RequiredVersion 4.4.0 -AllowPrerelease -force
    
  3. Connect to Azure using the Connect-AzAccount cmdlet.

  4. Sign into your subscription:

    Set-AzContext -Subscription "SubscriptionName"
    
  5. Get the vault:

    $vault = Get-AzRecoveryServicesVault -ResourceGroupName "rgName" -Name "vaultName"
    
  6. Get the list of backup items:

    • For Azure Virtual Machines

      $BackupItemList = Get-AzRecoveryServicesBackupItem -vaultId $vault.ID -BackupManagementType "AzureVM" -WorkloadType "AzureVM"
      
    • For SQL Server in Azure Virtual Machines

      $BackupItemList = Get-AzRecoveryServicesBackupItem -vaultId $vault.ID -BackupManagementType "AzureWorkload" -WorkloadType "MSSQL"
      
  7. Get the backup item.

    • For Azure Virtual Machines

      $bckItm = $BackupItemList | Where-Object {$_.Name -match '<vmName>'}
      
    • For SQL Server in Azure Virtual Machines

      $bckItm = $BackupItemList | Where-Object {$_.FriendlyName -eq '<dbName>' -and $_.ContainerName -match '<vmName>'}
      
  8. (Optional) Add the date range for which you want to view the recovery points. For example, if you want to view the recovery points from the last 120 days, use the following cmdlet:

     $startDate = (Get-Date).AddDays(-120)
     $endDate = (Get-Date).AddDays(0) 
    

    Note

    To view recovery points for a different time range, modify the start and the end date accordingly.

    By default, it's taken for the last 30 days.

Check the archivable status of all recovery points

You can now check the archivable status of all recovery points of a backup item using the following cmdlet:

$rp = Get-AzRecoveryServicesBackupRecoveryPoint -VaultId $vault.ID -Item $bckItm -StartDate $startdate.ToUniversalTime() -EndDate $enddate.ToUniversalTime() 

$rp | select RecoveryPointId, @{ Label="IsArchivable";Expression={$_.RecoveryPointMoveReadinessInfo["ArchivedRP"].IsReadyForMove}}, @{ Label="ArchivableInfo";Expression={$_.RecoveryPointMoveReadinessInfo["ArchivedRP"].AdditionalInfo}}

Check archivable recovery points

$rp = Get-AzRecoveryServicesBackupRecoveryPoint -VaultId $vault.ID -Item $bckItm -StartDate $startdate.ToUniversalTime() -EndDate $enddate.ToUniversalTime() -IsReadyForMove $true -TargetTier VaultArchive

This lists all recovery points associated with a particular backup item that are ready to be moved to archive (from the start date to the end date). You can also modify the start dates and the end dates.

Check why a recovery point can't be moved to archive

$rp = Get-AzRecoveryServicesBackupRecoveryPoint -VaultId $vault.ID -Item $bckItm -StartDate $startdate.ToUniversalTime() -EndDate $enddate.ToUniversalTime() -IsReadyForMove $false -TargetTier VaultArchive
$rp[0].RecoveryPointMoveReadinessInfo["ArchivedRP"]

Where $rp[0] is the recovery point for which you want to check why it's not archivable.

Sample output

IsReadyForMove  AdditionalInfo
--------------  --------------
False           Recovery-Point Type is not eligible for archive move as it is already moved to archive tier

The recovery points associated with a virtual machine are incremental. When you move a particular recovery point to archive, it's converted into a full backup, and then moved to archive. So, the cost savings associated with moving to archive depends on the churn of the data source.

Therefore, Azure Backup provides a recommended set of recovery points that might save cost, if moved together.

Note

  • The cost savings depends on various reasons and might not be the same for every instance.
  • Cost savings are ensured only when you move all recovery points contained in the recommendation set to the Vault-archive tier.
$RecommendedRecoveryPointList = Get-AzRecoveryServicesBackupRecommendedArchivableRPGroup -Item $bckItm -VaultId $vault.ID

Move to archive

Move-AzRecoveryServicesBackupRecoveryPoint -VaultId $vault.ID -RecoveryPoint $rp[0] -SourceTier VaultStandard -DestinationTier VaultArchive

Where, $rp[0] is the first recovery point in the list. If you want to move other recovery points, use $rp[1], $rp[2], and so on.

This cmdlet moves an archivable recovery point to archive. It returns a job that can be used to track the move operation, both from portal and with PowerShell.

View archived recovery points

This cmdlet returns all archived recovery points.

$rp = Get-AzRecoveryServicesBackupRecoveryPoint -VaultId $vault.ID -Item $bckItm -Tier VaultArchive -StartDate $startdate.ToUniversalTime() -EndDate $enddate.ToUniversalTime()

Restore with PowerShell

For recovery points in archive, Azure Backup provides an integrated restore methodology. The integrated restore is a two-step process.

  1. Involves rehydrating the recovery points stored in archive.
  2. Temporarily store it in the Vault-standard tier for a duration (also known as the rehydration duration) ranging from a period of 10 to 30 days. The default is 15 days. There are two different priorities of rehydration – Standard and High priority. Learn more about rehydration priority.

Note

  • The rehydration duration once selected can't be changed and the rehydrated recovery points stay in the standard tier for the rehydration duration.
  • The additional step of rehydration incurs cost.

For more information about various restore methods for Azure Virtual Machines, see Restore an Azure VM with PowerShell.

Restore-AzRecoveryServicesBackupItem -VaultLocation $vault.Location -RehydratePriority "Standard" -RehydrateDuration 15 -RecoveryPoint $rp -StorageAccountName "SampleSA" -StorageAccountResourceGroupName "SArgName" -TargetResourceGroupName $vault.ResourceGroupName -VaultId $vault.ID

To restore SQL Server, follow these steps. The Restore-AzRecoveryServicesBackupItem cmdlet requires two additional parameters, RehydrationDuration and RehydrationPriority.

View jobs

To view the move and restore jobs, use the following PowerShell cmdlet:

Get-AzRecoveryServicesBackupJob -VaultId $vault.ID

Move recovery points to Archive tier at scale

You can now use sample scripts to perform at scale operations. Learn more about how to run the sample scripts. You can download the scripts from here.

You can perform the following operations using the sample scripts provided by Azure Backup:

  • Move all eligible recovery points for a particular database/all databases for a SQL server in Azure VM to Archive tier.
  • Move all recommended recovery points for a particular Azure Virtual Machine to Archive tier.

You can also write a script as per your requirements or modify the above sample scripts to fetch the required backup items.
