## Examples

::: example
### Modifying Cache Folder Settings for Mount Server

This example shows how to specify a new cache folder for the `WinSrv2047` mount server. The mount server will keep cache in the `C:\Backup\Veeam\IRCache\` folder instead of the default `C:\ProgramData\Veeam\Backup\IRCache\` folder.

```
$server = Get-VBRServer -Name "WinSrv2047"
$mountoptions = New-VBRRepositoryMountServerOptions -MountServer $server -EnableVPowerNFS -MountFolder "C:\ProgramData\Veeam\Backup\IRCache\"
Set-VBRRepositoryMountServerOptions -Options $mountoptions -MountFolder "C:\Backup\Veeam\IRCache\"
```

Perform the following steps:

1. Run the [`Get-VBRServer`](get-vbrserver.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$server` variable.
2. Run the [`New-VBRRepositoryMountServerOptions`](new-vbrrepositorymountserveroptions.md) cmdlet. Specify the `MountServer`, `EnableVPowerNFS` and `MountFolder` parameters. Save the result to the `$mountoptions` variable.
3. Run the `Set-VBRRepositoryMountServerOptions` cmdlet. Set the `$mountoptions` variable as the `Options` parameter value. Specify the `MountFolder` parameter value.
