+# Object Storage
+
+GitLab supports using an object storage service for holding numerous types of data.
+In a high availability setup, it's recommended over [NFS](high_availability/nfs.md) and
+in general it's better in larger setups as object storage is
+typically much more performant, reliable, and scalable.
+
+## Options
+
+Object storage options that GitLab has tested, or is aware of customers using include:
+
+- SaaS/Cloud solutions such as [Amazon S3](https://aws.amazon.com/s3/), [Google cloud storage](https://cloud.google.com/storage).
+- On-premises hardware and appliances from various storage vendors.
+- MinIO. We have [a guide to deploying this](https://docs.gitlab.com/charts/advanced/external-object-storage/minio.html) within our Helm Chart documentation.
+
+## Configuration guides
+
+For configuring GitLab to use Object Storage refer to the following guides:
+
+1. Make sure the [`git` user home directory](https://docs.gitlab.com/omnibus/settings/configuration.html#moving-the-home-directory-for-a-user) is on local disk.
+1. Configure [database lookup of SSH keys](operations/fast_ssh_key_lookup.md)

+
+## Warnings, limitations, and known issues
+
+### Use separate buckets
+
+Using separate buckets for each data type is the recommended approach for GitLab.
+
+A limitation of our configuration is that each use of object storage is separately configured.
+[We have an issue for improving this](https://gitlab.com/gitlab-org/gitlab/-/issues/23345)
+and easily using one bucket with separate folders is one improvement that this might bring.
+
+There is at least one specific issue with using the same bucket:
+when GitLab is deployed with the Helm chart restore from backup
+[will not properly function](https://docs.gitlab.com/charts/advanced/external-object-storage/#lfs-artifacts-uploads-packages-external-diffs-pseudonymizer)
+unless separate buckets are used.
+
+One risk of using a single bucket would be that if your organisation decided to
+migrate GitLab to the Helm deployment in the future. GitLab would run, but the situation with
+backups might not be realised until the organisation had a critical requirement for the backups to work.
+
+### S3 API compatability issues
+
+Not all S3 providers [are fully compatible](../raketasks/backup_restore.md#other-s3-providers)
+with the Fog library that GitLab uses. Symptoms include:
+
+```plaintext
+411 Length Required
+```
+
+### GitLab Pages requires NFS
+
+If you're working to [scale out](high_availability/README.md) your GitLab implementation and
+one of your requirements is [GitLab Pages](../user/project/pages/index.md) this currently requires
+NFS. There is [work in progress](https://gitlab.com/gitlab-org/gitlab-pages/issues/196)
+to remove this dependency. In the future, GitLab Pages may use
+[object storage](https://gitlab.com/gitlab-org/gitlab/-/issues/208135).
+
+The dependency on disk storage also prevents Pages being deployed using the
+[GitLab Helm chart](https://gitlab.com/gitlab-org/charts/gitlab/-/issues/37).
+
+### Incremental logging is required for CI to use object storage
+
+If you configure GitLab to use object storage for CI logs and artifacts,
+[you must also enable incremental logging](job_artifacts.md#using-object-storage).
+
+### Proxy Download
+
+A number of the use cases for object storage allow client traffic to be redirected to the
+object storage back end, like when Git clients request large files via LFS or when
+downloading CI artifacts and logs.
+
+When the files are stored on local block storage or NFS, GitLab has to act as a proxy.
+This is not the default behaviour with object storage.
+
+The `proxy_download` setting controls this behaviour: the default is generally `false`.
+Verify this in the documentation for each use case. Set it to `true` so that GitLab proxies
+the files.
+
+When not proxying files, GitLab returns an
+[HTTP 302 redirect with a pre-signed, time-limited object storage URL](https://gitlab.com/gitlab-org/gitlab/-/issues/32117#note_218532298).
+This can result in some of the following problems:
+
+- If GitLab is using non-secure HTTP to access the object storage, clients may generate
+`https->http` downgrade errors and refuse to process the redirect. The solution to this
+is for GitLab to use HTTPS. LFS, for example, will generate this error:
+
+   ```plaintext
+   LFS: lfsapi/client: refusing insecure redirect, https->http
+   ```
+
+- Clients will need to trust the certificate authority that issued the object storage
+certificate, or may return common TLS errors such as:
+
+   ```plaintext
+   x509: certificate signed by unknown authority
+   ```
+
+- Clients will need network access to the object storage. Errors that might result
+if this access is not in place include:
+
+   ```plaintext
+   Received status code 403 from server: Forbidden
+   ```
+
+Getting a `403 Forbidden` response is specifically called out on the
+[package repository documentation](packages/index.md#using-object-storage)
+as a side effect of how some build tools work.
+
+### ETag mismatch
+
+Using the default GitLab settings, some object storage back-ends such as
+[MinIO](https://gitlab.com/gitlab-org/gitlab/-/issues/23188)
+and [Alibaba](https://gitlab.com/gitlab-org/charts/gitlab/-/issues/1564)
+might generate `ETag mismatch` errors.
+
+When using GitLab direct upload, the
+[workaround for MinIO](https://gitlab.com/gitlab-org/charts/gitlab/-/issues/1564#note_244497658)
+is to use the `--compat` parameter on the server.
+
+We are working on a fix to GitLab component Workhorse, and also
+a workaround, in the mean time, to
+[allow ETag verification to be disabled](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/18175).
