# S3 Compatible Settings

If you have selected to store backup files on an S3 compatible storage, specify the following settings:

1. [Account settings](#storage).
2. [Bucket settings](#bucket).

## Specifying Account Settings {#storage}

The **Account** step of the wizard is available if you have chosen to save backup files on an S3 compatible storage.

::: note

You can store backups only in the S3 compatible storage repositories that are accessible over the HTTPS protocol.

:::

To connect to the S3 compatible storage, specify the following:

1. In the **Service point** field, specify the address of your S3 compatible storage.

   If you want to connect to the repository using an IPv6 address and port number, you must use the following format: `IPv6:port`, where:

   - `IPv6` is the IPv6 address of the object storage.
   - `port` is the number of the port that Veeam Agent will use to connect to the object storage.

   For example: `https://2001-db8-1--bb8-c0b8-112.ipv6-literal.net:9000`

   If you want to connect to the repository using AWS PrivateLink for Amazon S3, use the following format: `bucket.<VPC_endpoint_ID>.s3.<region>.vpce.amazonaws.com`, where:

   - `VPC_endpoint_ID` is the unique VPC endpoint ID that Veeam Agent will use to access the cloud storage.
   - `region` is the AWS Region where the VPC endpoint and the S3 bucket are located.

   For example: `bucket.vpce-0abc123def456ghi7-01234567.s3.ap-northeast-1.vpce.amazonaws.com`

   To learn more about AWS PrivateLink for Amazon S3, see [AWS Documentation](https://docs.aws.amazon.com/AmazonS3/latest/userguide/privatelink-interface-endpoints.html#accessing-bucket-and-aps-from-interface-endpoints).

2. In the **Region** field, specify a storage region based on your regulatory and compliance requirements. 
3. In the **Access key** field, enter an access key ID.
4. In the **Secret key** field, enter a secret access key.

## Specifying Bucket Settings {#bucket}

The **Bucket** step of the wizard is available if you have chosen to save backup files on an S3 compatible storage and specified account settings to connect to the storage.

Specify settings for the bucket on the storage:

1. In the **Bucket** field, specify a bucket on the storage:

   1. Click **Browse**.
   2. In the **Buckets** window, select the necessary bucket and click **OK**.

2. In the **Folder** field, specify a folder in the bucket:

   1. Click **Browse**.
   2. In the **Folders** window, select the necessary folder and click **OK**.

   ::: tip

   You can also create a new folder in the bucket. To do this:

   1. In the **Folders** window, click **New Folder**.
   2. In the **Creating new folder** dialog window, enter a name for the folder and click **OK**.

   :::

3. In the **Retention policy** field, specify the number of days for which you want to store backup files in the target location. After this period is over, Veeam Agent will remove from the backup chain any restore points that are older than the specified retention period. By default, Veeam Agent keeps backup files for 7 days. The maximum retention period is limited to 9999 days. To learn more, see [Backup Retention Policy](retention.md).
4. To specify the GFS retention policy, select the **Keep certain full backups longer for archival purposes** check box and press **Configure**. In the **Configure GFS** window, specify how weekly, monthly and yearly full backups must be retained. For details, see [Specify GFS Retention Policy](backup_job_gfs_settings.md).
5. Select the **Make recent backups immutable for** check box to enable backup immutability and specify the immutability settings:

   - Select **For the entire duration of the retention policy** if you want the immutability period to depend on the retention policy of a backup job. This option is selected by default when you enable immutability for a backup job.

     ::: important

     Consider the following:

     - If the job retention exceeds the immutability period, the actual retention is counted as the job retention policy + the block generation period.
     - If the immutability period exceeds the job retention period, the actual retention is counted as the immutability period + the block generation period.

     For more information, see [How Backup Immutability Works](backup_immutability_hiw.md).

     :::

   - Select **For the minimum duration** if you want to specify a minimum immutability period manually. In the **Minimum immutability duration** field, specify the period in days. By default, Veeam Agent sets the period to 30 days.

     In this case, backup job retention settings are not considered in the calculation of the immutability period.

6. Click **Advanced** to specify additional backup job settings. For details, see [Specify Advanced Backup Settings](backup_job_advanced.md).
7. After you specified the bucket settings, click **Next**. Veeam Agent will create a new backup repository in the configured cloud storage location.
