Workload Policies

Trilio’s tenant driven backup service gives tenants control over backup policies. However, sometimes it may be too much control to tenants and the cloud admins may want to limit what policies are allowed by tenants. For example, a tenant may become overzealous and only uses full backups every 1 hr interval. If every tenant were to pursue this backup policy, it puts a severe strain on cloud infrastructure. Instead, if cloud admin can define predefined backup policies and each tenant is only limited to those policies then cloud administrators can exert better control over backup service.

Workload policy is similar to nova flavor where a tenant cannot create arbitrary instances. Instead, each tenant is only allowed to use the nova flavors published by the admin.
