End-of-contract data extraction The replication virtual machines are stored in a mixture of VMware and proprietary formats.
You can only get access to available recovery points via
the provided failover mechanism in Live or Test modes. When a VM is failed over, the data is available in
the same format in which it was stored. Professional services will be required to
extract and return consumer generated data. Such
services will be quantified based on the volume and nature of the consumer generated data. Professional
services will be based on our standard rate card
End-of-contract process The customer has the right to terminate the agreement at any point and must give notice to terminate
before the contract end date. Each agreement carries an economic break point, any termination of the
