## Examples

::: example
### Example 1. Adding Amazon S3 External Repository

This example shows how to add the Amazon S3 object storage repository named `New Repository` as an external repository into the backup infrastructure.

```
$account = Get-VBRAmazonAccount
$connect = Connect-VBRAmazonS3Service -Account $account -RegionType Global -ServiceType ExternalRepository
$bucket = Get-VBRAmazonS3Bucket -Connection $connect -Name "veeam-tw"
$folder = Get-VBRAmazonS3Folder -Name "frozenbucket" -Bucket $bucket -Connection $connect
Add-VBRAmazonS3ExternalRepository -Name "New Repository" -AmazonS3Folder $folder -Connection $connect
```

Perform the following steps:

1. Run the [`Get-VBRAmazonAccount`](get-vbramazonaccount.md) cmdlet. Save the result to the `$account` variable.
2. Run the [`Connect-VBRAmazonS3Service`](connect-vbramazons3service.md) cmdlet. Set the `$account` variable as the `Account` parameter value. Specify the `RegionType` and `ServiceType` parameter values. Save the result to the `$connect` variable.
3. Run the [`Get-VBRAmazonS3Bucket`](get-vbramazons3bucket.md) cmdlet. Set the `$connect` variable as the `Connection` parameter value. Specify the `Name` parameter value. Save the result to the `$bucket` variable.
4. Run the [`Get-VBRAmazonS3Folder`](get-vbramazons3folder.md) cmdlet. Specify the `Name` parameter value. Set the `$bucket` variable as the `Bucket` parameter value. Set the `$connect` variable as the `Connection` parameter value. Save the result to the `$folder` variable.
5. Run the `Add-VBRAmazonS3ExternalRepository` cmdlet. Specify the following settings:

   - Specify the `Name` parameter value.
   - Set the `$folder` variable as the `AmazonS3Folder` parameter value.
   - Set the `$connect` variable as the `Connection` parameter value.

### Example 2. Adding Amazon S3 External Repository and Decrypting the Imported Backup Files

This example shows how to add Amazon S3 object storage repository named `New Repository` as an external repository into the backup infrastructure. Veeam Backup & Replication will decrypt backup files that are imported from the external repository.

```
$account = Get-VBRAmazonAccount
$connect = Connect-VBRAmazonS3Service -Account $account[1] -RegionType Global -ServiceType ExternalRepository
$bucket = Get-VBRAmazonS3Bucket -Connection $connect -Name "veeam-tw"
$folder = Get-VBRAmazonS3Folder -Name "frozenbucket" -Bucket $bucket -Connection $connect
$securepassword = Read-Host -Prompt "Enter password" -AsSecureString
$key = Add-VBREncryptionKey -Password $securepassword
Add-VBRAmazonS3ExternalRepository -Name "New Repository" -AmazonS3Folder $folder -Connection $connect -DecryptBackups -DecryptionKey $key
```

Perform the following steps:

1. Run the [`Get-VBRAmazonAccount`](get-vbramazonaccount.md) cmdlet. Save the result to the `$account` variable.
2. Run the [`Connect-VBRAmazonS3Service`](connect-vbramazons3service.md) cmdlet. Specify the `Account`, `RegionType` and `ServiceType` parameter values. Save the result to the `$connect` variable.
3. Run the [`Get-VBRAmazonS3Bucket`](get-vbramazons3bucket.md) cmdlet. Set the `$connect` variable as the `Connection` parameter value. Specify the `Name` parameter value. Save the result to the `$bucket` variable.
4. Run the [`Get-VBRAmazonS3Folder`](get-vbramazons3folder.md) cmdlet. Specify the `Name` parameter value. Set the `$bucket` variable as the `Bucket` parameter value. Set the `$connect` variable as the `Connection` parameter value. Save the result to the `$folder` variable.
5. Run the [`Read-Host`](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/read-host?view=powershell-6) cmdlet. Specify the message which the console will display as a prompt. Specify the `AsSecureString` parameter. Save the result to the `$securepassword` variable.
6. Run the [`Add-VBREncryptionKey`](add-vbrencryptionkey.md) cmdlet. Specify the `Password` parameter. Save the result to the `$key` variable.
7. Run the `Add-VBRAmazonS3ExternalRepository` cmdlet. Specify the following settings:

   - Specify the `Name` parameter value.
   - Set the `$folder` variable as the `AmazonS3Folder` parameter value.
   - Set the `$connect` variable as the `Connection` parameter value.
   - Provide the `DecryptBackups` parameter.
   - Set the `$key` variable as the `DecryptionKey` parameter value.
