# Backup to Object Storage
[Veeam Backup & Replication](https://www.veeam.com/products/veeam-data-platform/backup-recovery.html) offers two options for backup to the Object Storage:
1\. Direct backup to Object Storage
2\. Backup to Object Storage as a capacity tier in the [Scale-out Backup Repository (SOBR)](https://docs.ionos.com/support/general-information/glossary-of-terms#scale-out-backup-repository-sobr).
## Direct backup to Object Storage
Follow these steps to configure direct backup:
1\. **Add Object Storage Repository:** In Veeam Backup & Replication, navigate to the backup infrastructure and add a new object storage repository, selecting S3 compatible and providing your IONOS Object Storage credentials. We recommend using the `eu-central-3` region for Veeam backups.
2\. **Configure Backup Jobs:** Set up or modify backup jobs to target the newly added IONOS Object Storage repository.
For more information, see [Add Backup Repository](/cloud/~/revisions/NfgM5VQuRjXRMfbR25yK/storage-and-backup/s3-object-storage/s3-tools/veeam-backup-and-replication/add-backup-repository.md).
## Backup using SOBR
[SOBR](https://docs.ionos.com/support/general-information/glossary-of-terms#sobr) in Veeam enables you to create a highly flexible and scalable backup storage solution by combining multiple storage resources into a single repository. It allows moving data from performance to capacity tiers automatically to optimize storage usage and cost.
Follow these steps to configure SOBR with Object Storage:
1\. **Create Performance Tier:** Add your primary, fast storage devices (local or network) as the performance tier in Veeam Backup & Replication.
2\. **Add Capacity Tier:** Integrate IONOS Object Storage as the capacity tier, allowing Veeam to offload older backup files to cost-effective object storage.
3\. **Policy Configuration:** Configure policies to define how and when data should be moved between the performance and capacity tiers.
In Veeam 12, both Performance and Capacity Tiers support multiple buckets without any limit and apply to users as follows:
* Existing users upgrading to v12 should consider setting up a new SOBR with multiple buckets, as Veeam does not redistribute existing VM backups across newly added buckets.
* For new users planning to integrate IONOS Object Storage in the Capacity Tier with a traditional SOBR configuration, it is advisable to start with multiple buckets.
Veeam automatically allocates VM backups across these buckets. While adding new buckets is possible later as well, Veeam does not reallocate existing VM backups to these new buckets; only new VM backups will utilize them. Utilizing multiple buckets in the Capacity Tier removes the necessity for multiple SOBRs.
## Recommended settings
| **Minimal Veeam Version** | Veeam 11a CP4 (11.0.1.126120220302) brings an important special fix when using [Object Lock](/cloud/~/revisions/NfgM5VQuRjXRMfbR25yK/storage-and-backup/s3-object-storage/settings/object-lock.md). |
| ---------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Recommended Object Storage regions** | `eu-central-3`. For more information, see [Endpoints](/cloud/~/revisions/NfgM5VQuRjXRMfbR25yK/storage-and-backup/s3-object-storage/s3-endpoints.md). |
| **Backup Job Storage Optimization** | Minimum—4 MB, recommended—8 MB and this option must be enabled via a registry key. For more information, see [Apply 8 MB blocks in the storage optimization setting](/cloud/~/revisions/NfgM5VQuRjXRMfbR25yK/storage-and-backup/s3-object-storage/s3-tools/veeam-backup-and-replication/recommended-settings.md#apply-8-mb-blocks-in-the-storage-optimization-setting). |
| **Immutability Retention Period** | The immutability retention period must be less or equal to the backup retention period. |
| **Object Storage Repository Task Limit** | Create a bucket for every 100 VMs or 200 TB of data to be backed up (Performance or Capacity Tier, depending on the use case). |
For more information, see [Recommended Settings](/cloud/~/revisions/NfgM5VQuRjXRMfbR25yK/storage-and-backup/s3-object-storage/s3-tools/veeam-backup-and-replication/recommended-settings.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.ionos.com/cloud/~/revisions/NfgM5VQuRjXRMfbR25yK/storage-and-backup/s3-object-storage/s3-tools/veeam-backup-and-replication/backup-to-object-storage.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
