Workload Quotas

Trilio enables OpenStack administrators to set Project Quotas against the usage of Trilio.

The following Quotas can be set:

• Number of Workloads a Project is allowed to have

• Number of Snapshots a Project is allowed to have

• Number of VMs a Project is allowed to protect

• Amount of Storage a Project is allowed to use on the Backup Target
