+# Geo with Object storage **[PREMIUM ONLY]**
+
+Geo can be used in combination with Object Storage (AWS S3, or
+other compatible object storage).
+
+## Configuration
+
+At this time it is required that if object storage is enabled on the
+**primary** node, it must also be enabled on each **secondary** node.
+
+**Secondary** nodes can use the same storage bucket as the **primary** node, or
+they can use a replicated storage bucket. At this time GitLab does not
+take care of content replication in object storage.
+
+For LFS, follow the documentation to
+[set up LFS object storage](../../../workflow/lfs/lfs_administration.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-core-only)
+
+You should enable and configure object storage on both **primary** and **secondary**
+nodes. Migrating existing data to object storage should be performed on the
+**primary** node only. **Secondary** nodes will automatically notice that the migrated
+files are now in object storage.
+
+## Replication
+
+When using Amazon S3, you can use
+[CRR](https://docs.aws.amazon.com/AmazonS3/latest/dev/crr.html) to
+have automatic replication between the bucket used by the **primary** node and
+the bucket used by **secondary** nodes.
+
+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/),
+although this only supports daily synchronization.
+
+For manual synchronization, or scheduled by `cron`, please have a look at:
+
+- [`s3cmd sync`](http://s3tools.org/s3cmd-sync)
+- [`gsutil rsync`](https://cloud.google.com/storage/docs/gsutil/commands/rsync)
