Backup and Restore Requirements

AB.

DRS (Disaster Recovery System) is a feature in Cisco Unified Communications Manager that allows for backup and restore of the system configuration and user data. When performing a restore operation, it is important to ensure that certain settings between the backup source and restore target are the same to avoid any issues.

The two settings that must be the same between the backup source and restore target with DRS in Cisco Unified Communications Manager are:

A. Server Hostname: The hostname of the server must be the same between the backup source and restore target. This is because the hostname is used to identify the server and ensure that the correct data is being restored to the correct server.

B. Server IP Address: The IP address of the server must also be the same between the backup source and restore target. This is because the IP address is used to identify the server on the network and ensure that the correct data is being restored to the correct server.

The other options listed, C. Cluster Security Password, D. NTP Servers, E. Domain Name, and F. Certificate Information, do not need to be the same between the backup source and restore target with DRS in Cisco Unified Communications Manager.

C. Cluster Security Password: The cluster security password is used to encrypt sensitive data in the system configuration backup. It does not need to be the same between the backup source and restore target as long as the password is known and entered correctly during the restore operation.

D. NTP Servers: The NTP (Network Time Protocol) servers are used to synchronize the system clock on the server. They do not need to be the same between the backup source and restore target as long as the correct NTP servers are configured on the restore target.

E. Domain Name: The domain name is used to identify the server on the network. It does not need to be the same between the backup source and restore target as long as the correct domain name is configured on the restore target.

F. Certificate Information: The certificate information is used to secure communication between servers and devices. It does not need to be the same between the backup source and restore target as long as the correct certificates are installed on the restore target.

In summary, when using DRS to backup and restore a Cisco Unified Communications Manager system, it is important to ensure that the server hostname and IP address are the same between the backup source and restore target.
