Replicating Volumes

On Compute Cloud@Customer, you can asynchronously replicate a boot volume, block volume, or volume group to a different infrastructure and synchronize the data at regular intervals. A replica is not a backup. A backup is a point-in-time copy that enables you to return to a previous version of a volume or volume group. A replica is always the current version of the data. Although a replica is different from a backup, a replica can be used for recovery. A replica can also be used as the source to create a new volume.

Note

Before you can configure storage replication, you must submit a request for Oracle Support to configure infrastructure peering. See Creating a Support Request. To access support, sign in to the Oracle Cloud Console as described in Sign In to the OCI Console.

Each volume or volume group can have only one replica. To create a replica on a different infrastructure, see Updating Replication Configuration for a Volume.

You cannot resize a volume that has replication enabled. When you resize a volume that has replication enabled, you must disable replication, which deletes the replica. After the volume is resized, you can re-enable replication for the volume. See Enabling Replication When You Update a Volume.

Replication cannot be enabled for a volume that is in a DR configuration.
