# Replicate a bucket to another region

Replication copies new objects written to a bucket into a bucket in another region, Delhi or Chennai.
This gives you a copy of incoming data in a second region.

## Before you begin

- A source bucket and a destination bucket, both in the same project, in different regions. Create the destination in the other region first; see
  [Create a bucket](/tir/tir-object-storage/how-to/create-a-bucket/).
- Object versioning on for both buckets; see
  [Use object versioning](/tir/tir-object-storage/how-to/use-object-versioning/).
- Matching encryption: replication works only between two encrypted buckets or between two
  unencrypted buckets.
- A destination that is free of other replication rules. A bucket can be the source of one rule only.
  Replication runs one way, from the source to its one destination, and stops there.
- Permission to create datasets in the project. A Member gets it through a policy that allows creating datasets. Setting up a rule needs create and update permission, enabling or disabling it needs update
  permission, and removing it needs delete and update permission.

## Create the rule

1. In the list, select the bucket's row and open the **Replication** tab. It lists the conditions
   for a rule, the same ones as in **Before you begin**.
2. Select **Configure Replication Rule**, or open the bucket's **Actions** menu and select
   **Replication Rule**.
3. Choose **Destination Region**. It offers the regions your account can use, other than the bucket's
   own. If the list is empty, the dialog says "No region is available as a replication destination for
   this bucket."
4. Choose **Destination Bucket**. The list offers only eligible buckets; when it is empty, the dialog says "No eligible bucket in
   `<region>`. A destination has to be in this project, have versioning enabled, match this bucket's
   encryption settings, and not already be part of another replication rule."
5. Select **Save**. The portal shows "Replication rule created successfully".

Replication copies only objects written after the rule exists; objects already in the bucket stay
in the source only.

## Manage the rule

The **Replication** tab lists the rule with **Source** and **Destination**, each with its region,
**Status** (**Active** or **Disabled**), **Created On**, and **Actions**. **Configure Replication Rule**
is available only before a rule exists.

- **Disable** stops copying new objects and keeps the objects already replicated. **Enable**
  starts copying new objects again.
- **Delete** removes the rule and keeps the objects already copied.

To suspend a bucket's versioning or delete the bucket, delete its rule first.

## Check the replication

The rule shows **Active** on the **Replication** tab. Upload an object to the source bucket, then look for it in the **Data Objects** tab of the destination bucket.

New objects now reach the other region. For help with a message, see
