::: example
### Example 2: Rescanning Specific Backup Proxy Servers

This example shows how to rescan backup proxy servers with the `172.17.53.53` and `172.17.51.60` IP addresses.

```
$proxy1 = Get-VBOProxy -Hostname 172.17.53.53
$proxy2 = Get-VBOProxy -Hostname 172.17.51.60
Sync-VBOProxy -Proxy ($proxy1, $proxy2)
```

Perform the following steps:

1. Run the [`Get-VBOProxy`](get-vboproxy.md) cmdlet. Specify the `Hostname` parameter value. Save the result to the `$proxy1` variable.
2. Run the [`Get-VBOProxy`](get-vboproxy.md) cmdlet. Specify the `Hostname` parameter value. Save the result to the `$proxy2` variable.
3. Run the `Sync-VBOProxy` cmdlet. Set the `$proxy1` and `$proxy2` variables as the `Proxy` parameter value.
