# Geo with Object storage **(PREMIUM SELF)**
|
|
|
|
Geo can be used in combination with Object Storage (AWS S3, or other compatible object storage).
|
|
|
|
Currently, **secondary** sites can use either:
|
|
|
|
- The same storage bucket as the **primary** site.
|
|
- A replicated storage bucket.
|
|
- Local storage, if the primary uses local storage.
|
|
|
|
The storage method (local or object storage) for files is recorded in the database, and the database
|
|
is replicated from the **primary** Geo site to the **secondary** Geo site.
|
|
|
|
When accessing an uploaded object, we get its storage method (local or object storage) from the
|
|
database, so the **secondary** Geo site must match the storage method of the **primary** Geo site.
|
|
|
|
Therefore, if the **primary** Geo site uses object storage, the **secondary** Geo site must use it too.
|
|
|
|
To have:
|
|
|
|
- GitLab manage replication, follow [Enabling GitLab replication](#enabling-gitlab-managed-object-storage-replication).
|
|
- Third-party services manage replication, follow [Third-party replication services](#third-party-replication-services).
|
|
|
|
[Read more about using object storage with GitLab](../../object_storage.md).

|
## Enabling GitLab-managed object storage replication
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/10586) in GitLab 12.4.
|
|
|
|
WARNING:
|
|
This is a [**beta** feature](https://about.gitlab.com/handbook/product/#beta) and is not ready yet for production use at any scale. The main limitations are a lack of testing at scale and no verification of any replicated data.
|
|
|
|
**Secondary** sites can replicate files stored on the **primary** site regardless of
|
|
whether they are stored on the local file system or in object storage.
|
|
|
|
To enable GitLab replication:
|
|
|
|
1. On the top bar, select **Menu > Admin**.
|
|
1. On the left sidebar, select **Geo > Nodes**.
|
|
1. Select **Edit** on the **secondary** site.
|
|
1. In the **Synchronization Settings** section, find the **Allow this secondary node to replicate content on Object Storage**
|
|
checkbox to enable it.
|
|
|
|
For LFS, follow the documentation to
|
|
[set up LFS object storage](../../lfs/index.md#storing-lfs-objects-in-remote-object-storage).
|
|
|
|
For CI job artifacts, there is similar documentation to configure
|
|
[jobs artifact object storage](../../job_artifacts.md#using-object-storage)
|
|
|
|
For user uploads, there is similar documentation to configure [upload object storage](../../uploads.md#using-object-storage)
|
|
|
|
If you want to migrate the **primary** site's files to object storage, you can
|
|
configure the **secondary** in a few ways:
|
|
|
|
- Use the exact same object storage.
|
|
- Use a separate object store but leverage your object storage solution's built-in
|
|
replication.
|
|
- Use a separate object store and enable the **Allow this secondary node to replicate
|
|
content on Object Storage** setting.
|
|
|
|
GitLab does not currently support the case where both:
|
|
|
|
- The **primary** site uses local storage.
|
|
- A **secondary** site uses object storage.
|
|
|
|
## Third-party replication services
|
|
|
|
When using Amazon S3, you can use
|
|
[Cross-Region Replication (CRR)](https://docs.aws.amazon.com/AmazonS3/latest/dev/crr.html) to
|
|
have automatic replication between the bucket used by the **primary** site and
|
|
the bucket used by **secondary** sites.
|
|
|
|
If you are using Google Cloud Storage, consider using
|
|
[Multi-Regional Storage](https://cloud.google.com/storage/docs/storage-classes#multi-regional).
|
|
Or you can use the [Storage Transfer Service](https://cloud.google.com/storage-transfer/docs/),
|
|
although this only supports daily synchronization.
|
|
|
|
For manual synchronization, or scheduled by `cron`, see:
|
|
|
|
- [`s3cmd sync`](https://s3tools.org/s3cmd-sync)
|
|
- [`gsutil rsync`](https://cloud.google.com/storage/docs/gsutil/commands/rsync)
