Cisco Cisco Unified IP Interactive Voice Response (IVR) 8.0(1) インストールガイド

The BARS must be configured so that only one server in the Cisco CRS 
cluster is the data source server. In this way, a scheduled backup will not back 
up the cluster multiple times. However, even though only one server in the 
Cisco CRS cluster is configured as the data source server, all nodes in the 
cluster must be configured as backup targets.

For detailed information about installing, configuring, and operating the 
BARS, refer to the latest version of Cisco IP Telephony Backup and Restore 
System (BARS) Administration Guide, which is available at this URL:

After you complete an upgrade or a restore procedure from a Cisco CRS 
4.0(x) deployment that includes high availability, follow these steps to 
confirm that the procedure is successful:

Start and log in to the Cisco CRS Administration application, choose 
System > Datastore Control Center, and click the Historical link.

For the server for which the Replication Type is Publication Snapshot 
Agent, make sure that the Replication Status is in STOPPED state and 
that the LastAction shows “A snapshot of n article(s) was generated.” If 
the LastAction shows something else while the Replication Status is in 
STOPPED state, click the radio button for the Publication Snapshot 
Agent and then click Restart.

For server for which the Replication Type is Subscription Agent, make 
sure that the Replication Status is in RUNNING state and that the 
LastAction shows “No data needed to be merged.” If the Replication 
Status is in STOPPED state, click the radio button for the Publication 
Snapshot Agent and then click Restart, then click the radio button for the 
Subscription Agent and then click Restart.

Repeat these steps for the Repository and the Agent Datastores.
