What is the Recovery Point Objective in this plan?

A customer has two data centers (Site A and Site B) and in each data center there is an Isilon
cluster. They are replicating data between the sites using SyncIQ.
You have been reviewing their disaster recovery plan and found the following:
The policies specify that SyncIQ runs a replication job every four hours and that the job finishes
within one hour.
Three additional hours will be needed to get servers and the network redirected to work from
Site B.

What is the most likely reason the failback policy does not replicate data to the primary cluster?

An Isilon customer created a SyncIQ policy to replicate data from a primary cluster to an offsite
secondary cluster. The primary cluster becomes unavailable, and the customer has completed a
failover onto the secondary cluster.
The primary cluster becomes available again, so the customer would like to fail back data to the
primary cluster. The failback process does not replicate data.
What is the most likely reason the failback policy does not replicate data to the primary cluster?
