Verify backup files before restore in another server

[DanielEriksson-Avega]

Hi!
I have a case where I take backups (full + transactions) from an on-prem database, these backups are copied to a storage account in azure. I am using these backups to refresh a test database to point in time in another location. But sometimes backups are not properly copied and the restore will not be done.

I want to verify the backup files before even stop the test application and trying to restore the database.
fyi: I cant read the backup history from the source system, only the backup file in the storage account.

I have been trying to use a combination of the commands and got something like below.
Is this the way to do it or is there any other/more effective way of verifying the files before executing the restore command?

$blobs = Get-AzStorageBlob -Context $context -Container 'mycontainer'
$filteredblobs = ($blobs).ICloudBlob.Uri.AbsoluteUri
$backups = Get-DbaBackupInformation -SqlInstance 'mytestserver' -Path $filteredblobs -AzureCredential AzureCredentials -DirectoryRecurse
$FilteredBackups = $backups | Select-DbaBackupInformation -RestoreTime $pointintime -DatabaseName 'mysourcedb'
$formattedbackups = $FilteredBackups | Format-DbaBackupInformation -ReplaceDatabaseName 'mytargetdb'
$formattedbackups | Test-DbaBackupInformation -SqlInstance 'mytestserver' -WithReplace
$PassedDbs = $formattedbackups | Where-Object {$_.IsVerified -eq $True}

if($PassedDbs)
{
Write-Output 'Backup is okay'
#restore-DbaDatabase
}
