8.9. Replicating S3 data between datacenters¶

Acronis Cyber Infrastructure can store replicas of S3 cluster data and keep them up to date in multiple geographically distributed datacenters with S3 clusters based on Acronis Cyber Infrastructure. Geo-replication reduces the response time for local S3 users accessing the data in a remote S3 cluster or remote S3 users accessing the data in a local S3 cluster, as they do not need to have an Internet connection.

Geo-replication schedules the update of the replicas as soon as any data is modified. Geo-replication performance depends on the speed of Internet connection, the redundancy mode, and cluster performance.

If you have multiple datacenters with enough free space, it is recommended to set up geo-replication between S3 clusters residing in these datacenters.

To set up geo-replication between S3 clusters, exchange tokens between datacenters by doing the following:

1. In the admin panel of a remote datacenter, open the Storage services > S3 > Geo-replication screen.

   

2. In the section of the home S3 cluster, click Token. On the Get token pane, copy the token.

3. In the admin panel of the local datacenter, open the Storage services > S3 > Geo-replication screen, and then click Add datacenter.

   

4. Enter the copied token, and then click Add.

5. Configure the remote S3 cluster the same way.

After you enable geo-replication for the clusters, you can replicate their data per bucket, as described in Managing geo-replication in S3 buckets.
