`<CommonParameters>`

This cmdlet supports Microsoft PowerShell common parameters. For more information on common parameters, see [ Microsoft Docs](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_commonparameters?view=powershell-7).

## Output Object
The cmdlet returns the `VBRAzureBlobServer` object that contains settings of Microsoft Azure Blob storage as unstructured data source.

## Examples

::: example
### Modifying Settings of Microsoft Azure Blob Storage Added as Unstructured Data Source

This example shows how to set the high speed for Veeam Backup & Replication to read data from Microsoft Azure Blob storage added as unstructured data source to the inventory.

```
$server = Get-VBRUnstructuredServer -Name "Azure OS"
Set-VBRAzureBlobServer -Server $server -BackupIOControlLevel High
```

Perform the following steps:

1. Run the [`Get-VBRUnstructuredServer`](get-vbrunstructuredserver.md) cmdlet. Specify the `Name` parameter values. Save the result to the `$server` variable.
2. Run the `Set-VBRAzureBlobServer` cmdlet. Set the `$server` variable as the `Server` parameter value. Set the `High` option for the `BackupIOControlLevel` parameter.
