# Replication Group Options for OpenStack

When you configure a replication group for an OpenStack destination, identify source VMs, and then provide values for replication to the OpenStack destination site.

You can replicate to OpenStack from OpenStack streaming backups.

Note

Before you can add an instance to a replication group, the instance must be backed up at least one time.

## Content Options

- Hypervisors: Select the hypervisor for the source VMs.

  When you edit an existing replication group, you cannot change this value.

- Name: Enter a descriptive name for the replication group, or change the name.

- Select VM group: Select an existing VM group, or select Create new VM group to add specific VMs and create a new VM group.

  When you edit an existing replication group, you cannot change this value.

- Select VMs: Select specific virtual machines to be replicated, and then click OK.

  You can select VMs from the specified VM group.

- Plan: When you choose to create a new VM group, select a previously defined backup plan for the group.

## Target Options

- Recovery target: Select a previously defined recovery target or click Create new to create a new recovery target.

  When you edit an existing replication group, you cannot change this value.

- Access node: Select a VSA proxy that can perform the replication operation.

### Advanced Options

- Unconditionally overwrite if it already exists: When you select this option, the first replication operation replaces an existing instance with the same name in the target location, even if the destination instance is running.

  Replication operations from incremental backups are not affected by this setting. Subsequent incremental backups and replication updates are applied to the destination instance without overwriting the instance. If the destination instance is currently running, the replication operation fails.

- Select copy: Select the copy of backup data to use to create destination instances.

## Override Options

To change the destination settings for specific VMs, select the VMs from the Virtual machine list.

To apply any override changes to an existing replication group, you must run a new replication job after making the changes. Any overrides made between a replication job and a failover job will not take effect until the next replication and failover jobs. You can enter the following information:

- VM display name to: Enter the display name for the destination instance, or enter a prefix or suffix to apply to multiple instances.

  You can change this value only when adding a new instance.

- Availability zone: Select the destination zone.

  You can change this value only when adding a new instance.

- Additional options:

  - Volume type: Select a volume type that is defined for the zone of the source volumes.

  - Flavor: Select a flavor that is at or above the original configuration.

  - Security group: Select a predefined security group that defines the required network access.

  - Key pair: Select a key pair that identifies the ownership for the converted instance.

  - Network interface: Select a network interface that is available in the destination.
