Replication policies are sets of rules that define and control the replication attributes on a VMware Cloud Director organization level.

Replication Attributes Enforced by Replication Policies

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

  • Whether custom SLA settings are allowed in the replications or to use set SLA profiles. For more information, see Configuring SLA Profiles.
  • Whether an organization can be used as a replication source for outgoing replications.
  • Whether an organization can be used as a replication destination for incoming replications.
  • The maximum number of virtual machine replications that can be created for an organization.
  • The maximum number of point-in-time instances, subjected to an automatic retention, per single replication. For more information, see Using Instances.
  • The maximum number of stored instances, not subjected to an automatic retention, per single replication. For more information, see Using Instances.
  • The maximum throughput allowed per a VMware Cloud Director Availability On-Premises Appliance. For more information, see Bandwidth Throttling.
  • The minimum allowed Recovery Point Objective (RPO) for an organization. For more information, see Using Replications.

Default Replication Policy

The default replication policy applies to organizations that are not associated with a custom replication policy. The service providers might use only the default replication policy. In this case, to enable replication, the default replication policy attributes must be modified to allow incoming and or outgoing replications.

Table 1. Default Replication Policy Attributes
Setting Default Value
Policy name Default Policy
Allow custom SLA settings Enabled
Allow outgoing replications Disabled *
Allow incoming replications Disabled **
Maximum number of VM replications Not available **
Max point-in-time instances per replication Not available **
Max stored instances per replication Not available **
Enable bandwidth throttling Disabled
Minimum allowed RPO Not available **
Note: * By default, the Default Policy does not allow any replications. The state of incoming replications controls the remaining ** settings. To allow incoming and or outgoing replications, the Default Policy must be modified or a custom replication policy must be created and assigned to the organizations.

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 source organization allows outgoing replications.
  • Whether the destination organization allows incoming replications.
  • 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 point-in-time 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 the replication attributes is violated, the replication cannot be created.
