Once the server in the Active group is restored to normal operation, and a CMS server requests
for the recordings and data occurred during the time the active server failed, the requests will
be fulfilled by a shared volume on the redundant server. Due to the concerns with network
bandwidth and processing power, the restored active server does not synchronize its recording
pool with that on the redundant server after the failover and failback process.
