# Move a Backup Repository
In May 2024, we started to introduce regions with contract-owned buckets, providing enhanced performance and resilience. Contract-owned buckets are available in the `eu-central-3` region or in the `us-central-1` region. A new 92-character access key is required for this region.
To move a backup repository to one of these regions, follow these steps (example configuration for region `eu-central-3`):
1\. **Create a new access key:** Check your access key length in the [Key Management](https://docs.ionos.com/cloud/backup-and-storage/ionos-object-storage/concepts/key-management). If it is 20 characters long, you need to create a new 92-character key compatible with all regions. For more information, see [Generate a Key](https://docs.ionos.com/cloud/backup-and-storage/ionos-object-storage/get-started/generate-key).
2\. **Create a new contract-owned bucket with an Object Lock:** Create a new contract-owned bucket in the `eu-central-3` region with Object Lock enabled. For more information, see [Create a Bucket](https://docs.ionos.com/cloud/backup-and-storage/ionos-object-storage/get-started/create-bucket) and refer to the "contract-owned buckets" section.

**Note:** Select the **No default retention** option as the mode for the Object Lock.
{% endhint %}
3\. **Set up Veeam storage optimization:** To do so, follow the steps in [Set up Veam storage optimization](#set-up-veeam-storage-optimization).
4\. **Create backup repository:** Creta an Object Storage as an object repository in Veeam. To do so, follow the steps in [Create Object Storage as an object repository in Veeam](https://docs.ionos.com/cloud/backup-and-storage/ionos-object-storage/s3-tools/add-backup-repository#create-object-storage-as-an-object-repository-in-veeam).
5\. **Move the backup repository:** You need to move the backup repository to the new Object Storage region. To do so, follow these steps:
* Right-click on the **Backup Jobs** name in the **Object Storage** section of the **Backup** tab and select **Move backup**.
* Specify the target repository to move backups to and click **OK**. The migration of your backup repository will start. The data will be transferred directly from one region to another.
**Result:** The Veeam backup repository is successfully moved to the `eu-central-3` Object Storage region.
## Set up Veeam storage optimization
1\. Click the **Backup** section under **Jobs**.
2\. Select the required backup job, right-click on it, and choose **Edit** in the menu.
3\. Click **Storage**, go to **Advanced Settings** and change the tab to **Storage**.
{% hint style="info" %}
**Note:** We recommend using at least 4 MB in Veeam to benefit from better performance, and 8 MB storage blocks are a preferred choice, but these blocks are unavailable in the interface by default and must be enabled via a registry key.
{% endhint %}
4\. In the **Storage optimization** dropdown list, choose 4 MB or 8 MB (marked as "not recommended"). Disregard this "not recommended" mark that you see in the web interface.
5\. *(Optional)* If you want to benefit from better performance, follow the instructions to enable 8 MB blocks:
* Open the Registry Editor.
* Navigate to `Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication`
* Add a new `DWORD` (32-bit) value named `UIShowLegacyBlockSize`.
* Set the value of `UIShowLegacyBlockSize` to 1. Now, the 8 MB block option will be available in the interface.
* To apply the new storage configuration as the default for all future backup jobs, click **Save as Default** at the bottom of the Advanced Settings screen. This will ensure the settings are automatically used for any new backup jobs created.
{% hint style="success" %}
**Result:** The Veeam storage optimization is successfully set up.
{% endhint %}
