### Set up storage settings

Choose the settings for the storage:

* **Deduplication type** - enable or disable data deduplication. For more details, please refer to the [Deduplication](https://docs.cloudback.it/managing-backups/data-deduplication) documentation
* **Archive type** - enable or disable archive password protection. For more details, please refer to the [Password-Protected Archives](https://docs.cloudback.it/security-and-compliance/password-protected-archives) documentation
* **Archive name pattern** - configure the archive name pattern, which is used to generate the name of the backup archive. For more details, please refer to the [Archive Name Pattern](https://docs.cloudback.it/managing-backups/archive-name-pattern) documentation

### Create a new Amazon S3 Glacier Vault

To upload backups to Amazon S3 Glacier, you need to have a vault. You can find more information on how to create a vault in the [Amazon S3 Glacier documentation](https://docs.aws.amazon.com/amazonglacier/latest/dev/getting-started-create-vault.html). After creating a vault, you need to provide the Vault ARN in the `Step 1` field. If you already have a vault, you can just provide the ARN of the existing vault.

### Apply vault access policy

After you type a vault ARN in the `Step 1` field, Cloudback will generate a vault access policy for you. The generated policy document is available in the `Step 2` field. You need to apply this policy to the vault to allow Cloudback to access it. For more information on how to apply the vault access policy, please refer to the corresponding [Amazon S3 Glacier documentation page](https://docs.aws.amazon.com/amazonglacier/latest/dev/vault-access-policy.html).

### Save storage

Click on `Save` button to save the new storage. You can also use a `Test` button to check if the storage is configured correctly. After saving the storage, you can use it for storing backups of your repositories.

All storage settings can be changed later in the `Storages` page. To edit the storage settings, click on the `Edit` button next to the storage you want to edit.

## Change the storage for a repository

You can change the storage for a particular repository in the [Repository Details](https://docs.cloudback.it/dashboard/repository-details) page. Also, you can assign it to multiple repositories through the [Bulk Operations](https://docs.cloudback.it/managing-backups/bulk-operations).
