## Output Object
The cmdlet returns the `VBRCDPProxy` object that contains CDP proxies to the backup infrastructure settings.

## Examples

::: example
### Example 1. Modifying CDP Proxy Cache Size

This example shows how to modify a size of the cache that is used by the `Proxy05` CDP proxy.

```
$proxy = Get-VBRCDPProxy -Name "Proxy05"
Set-VBRCDPProxy -Proxy $proxy -CacheSize "25"
```

Perform the following steps:

1. Run the [`Get-VBRCDPProxy`](get-vbrcdpproxy.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$proxy` variable.
2. Run the `Set-VBRCDPProxy` cmdlet. Set the `$proxy` variable as the `Proxy` parameter value. Specify the `CacheSize` parameter value.

:::

::: example
### Example 2. Modifying CDP Proxy Cache Location

This example shows how to modify a path to the folder where the `Proxy05` CDP proxy keeps the cache.

```
$proxy = Get-VBRCDPProxy -Name "Proxy05"
Set-VBRCDPProxy -Proxy $proxy -CachePath "C:\CacheFolder"
```

Perform the following steps:

1. Run the [`Get-VBRCDPProxy`](get-vbrcdpproxy.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$proxy` variable.
2. Run the `Set-VBRCDPProxy` cmdlet. Set the `$proxy` variable as the `Proxy` parameter value. Specify the `CachePath` parameter value.
