Cisco Cisco Unified IP Interactive Voice Response (IVR) 8.0(1) Installation Guide

The restore process restores Cisco CRS deployment and configuration settings to 
their values that are stored in the most recent BARS backup, replacing any 
changes that you have made since that backup. For example, if you added or 
removed servers, software components, or languages after the last backup, these 
changes will not remain after the restore. Similarly, any configuration changes 
that you made in Cisco CRS Administration after the last backup will revert to 
their last back-up values.

The Cisco CRS restore process also checks all servers in the cluster, and reinstalls 
or repairs missing or corrupted Cisco CRS binary files, shortcuts, and registry 
entries for every server in the Cisco CRS cluster. (This process is equivalent to 
running the recover procedure on every server in the cluster.)

You can perform the restore procedure from any server in the Cisco CRS cluster. 
The restore process can take up to an hour to complete.

You can browse into the Cisco CRS Administration application while you are 
performing a restore procedure, but the upgrade process prevents you from 
making configuration changes during this time.

Make sure to perform the tasks in the 

 before you start the recover procedure.

Also, make sure that Internet Explorer is configured for use with the BARS, as 
described in the 

In addition, make sure to use a valid archive file during the restore process. 
Otherwise, the process might fail or complete with improper configuration 
information.
