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

As a service provider you 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 set 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.
  • General limits
    • The maximum number of replications that can be created for an organization.
    • The maximum throughput allowed per each VMware Cloud Director Availability On-Premises Appliance. For more information, see Bandwidth Throttling.

Default Policy

The default replication policy applies to all organizations that are not associated with a custom replication policy. If only using the default policy, without creating custom policies, to enable the replications, you must modify the default policy attributes to allow incoming and or outgoing migrations and or protections.

Table 1. Default Policy Attributes
Setting Default Value
Policy name Default Policy
Incoming migrations Enabled
Outgoing migrations Enabled
Incoming protections Disabled
Outgoing protections Disabled
Custom SLA settings Enabled
Max rotated instances per protection Not available *
Max stored instances per protection Not available *
Minimum allowed RPO Not available *
Limit the number of configured replications Disabled
Bandwidth throttling Disabled

* To select and configure the maximum number of rotated or stored instances or RPO, you must first select the incoming protections.

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.

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 assigned replication policy to the destination organization allows custom SLA settings to be set in the replication or to use the set SLA profiles.
  • 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 on the destination organization the total number of allowed virtual machine replications is not exceeding, including both incoming from on-premises and cloud replications.
  • 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.

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