The replication policies are sets of rules controlled by the service provider that define and control the replication attributes on a VMware Cloud Director organization level.

Replication Attributes Enforced by Replication Policies

The service provider can assign a single replication policy to multiple VMware Cloud Director organizations to control the following replication attributes:

  • Migration
    • Whether an organization can be used as a replication destination for incoming migrations.
    • Whether an organization can be used as a replication source for outgoing migrations.
  • Protection
    • Whether an organization can be used as a replication destination for incoming protections.
    • Whether an organization can be used as a replication source for outgoing protections.
  • Whether custom SLA settings are allowed in the replications or to use preset SLA profiles. For more information, see Configuring SLA Profiles.
  • The maximum number of rotated instances, automatically managed and subjected to an automatic retention, per single replication. For more information, see Using Instances.
  • The maximum number of stored instances, manually managed and not subjected to an automatic retention, per single replication. For more information, see Using Instances.
  • The minimum allowed Recovery Point Objective (RPO) for an organization. For more information, see Using Replications.
  • Events and Notifications tenants settings changes, allowing tenants to manage their event notifications. For more information, see Events and Notifications and Configure Tenants Events in the VMware Cloud Director Availability Administration Guide.
  • General limits:
    • The maximum number of replications, including both replications and protections that can be created for an organization. Deselecting this limit allows unlimited number of incoming replications.
    • The maximum throughput allowed per each VMware Cloud Director Availability On-Premises Appliance. For more information, see Bandwith Throttling in the VMware Cloud Director Availability Administration Guide.

Default Policy

The default replication policy applies to all organizations that are not associated with a custom replication policy.

Note: By default, the Default Policy does not allow any protections. Neither incoming nor outgoing protections are allowed, unless you modify the Default Policy, for all organizations not assigned with a custom policy.

To enable protections when only using the default policy, without creating custom policies, you must modify the default policy attributes and allow incoming and or outgoing protections.

Table 1. Default Policy Attributes
Setting Default Value
Policy name Default Policy
Incoming migrations Selected. In both directions, the migrations are allowed by default.
Outgoing migrations
Incoming protections Deselected. In both directions, the protections are disallowed by default.
Outgoing protections
Custom SLA settings Selected
Max rotated instances per protection Unavailable. To select and configure the maximum number of rotated or stored instances or RPO, first select the incoming protections.
Max stored instances per protection
Minimum allowed RPO
Settings changes Selected
Limit the number of configured replications Deselected (unlimited). To select and configure the limit for the number of configured replications, the incoming migrations, or incoming protections, or both must be selected.
Bandwidth throttling Deselected (unlimited)

New Replication Validation

When creating a protection or a migration, the New Replication wizard validates the replication attributes of the policy that is assigned to the organization.
  • Whether the destination organization allows incoming migrations.
  • Whether the source organization allows outgoing migrations.
  • Whether the destination organization allows incoming protections.
  • Whether the source organization allows outgoing protections.
  • Whether the assigned replication policy to the destination organization allows setting custom SLA settings in the replication or must be using the preset SLA profiles.
  • Whether the number of rotated instances per replication of the new replication complies with the policy that is assigned to the destination organization.
  • Whether the number of stored instances per replication of the new replication complies with the policy that is assigned to the destination organization.
  • Whether the RPO of the new replication is higher than or equal to the minimum RPO of the policy that is assigned to the destination organization.
  • Whether the total number of allowed incoming virtual machine replications, both migrations and protections, incoming from on-premises sites and from cloud sites, does not exceed the limit that is assigned to the destination organization.
  • Whether the network throughput per each VMware Cloud Director Availability On-Premises Appliance does not exceed the maximum throughput of the policy that is assigned to the destination organization.

If any of these replication attributes is violated, the new replication cannot be created.
