This guide provides an overview of the Disaster Recovery System, describes how to use the Disaster Recovery System, and provides procedures for completing various backup and restore related tasks.
Cisco Disaster Recovery System (Cisco DRS), which can be invoked from Cisco Unified Contact Center Express Administration, provides full data backup and restore capabilities for all servers in a Cisco Unified Contact Center Express (Unified CCX) cluster. The system automatically activates both the Master Agent and the Local Agent immediately after installation on the server and in case of HA setup it is activated on all nodes in the cluster. While a backup or restore is running, you cannot perform any Operating System (OS) Administration tasks because Cisco DRS blocks all OS Administration requests by locking the platform API. To access Cisco DRS, choose Disaster Recovery System from the Navigation drop-down list box in the upper-right corner of the Cisco Unified CCX Administration window. The system automatically activates the Master Agent service on each node of the cluster, but the Master Agent is functional only on the first node. You can access the MA through Cisco DRS user interface to perform activities such as configuring backup devices, scheduling backups by adding new backup schedules, viewing or updating an existing schedule, displaying status of executed schedules, and performing system restoration. Navigate to Cisco Unified CCX Administration, select Disaster Recovery System from the Navigation drop-down list box in the upper-right corner of the Cisco Unified CCX Administration window, and click Go.
Log in to the Disaster Recovery System with the same Platform Administrator username and password that you use to log in to Cisco Unified Operating System Administration. Navigate to Cisco Unified CCX Administration, select Disaster Recovery System from the Navigation menu in the upper-right corner of the Cisco Unified CCX Administration window, and click Go.
Sign in to the Disaster Recovery System by using the same administrator username and password that you use for Cisco Unified Communications Operating System Administration.
Log in to the Cisco DRS by using the same Platform Administrator username and password that you use to log in to Cisco Unified Operating System Administration.
When performing a system data restoration, you can choose which node in the cluster you want to restore considering both stand alone (SA) and high availability (HA).
When you restore from a disaster recovery situation, phones no longer recognize their configuration or ITL files after the DRS restore if the restored server was the TFTP server. When you try to install a new version or a COP file, you get the The system is currently locked by another process. So from Cisco Unified CM Administration page, select the Cisco Unified Serviceability option from the Navigation drop-down menu, and click Go. 5 Preface Purpose, page v Audience, page v Related Documents, page v Obtaining Documentation and Submitting a Service Request, page vi Cisco Product Security Overview, page vi Purpose The Disaster Recovery System Administration Guide for Cisco Unified Communications Manager provides an overview of the Disaster Recovery System, describes how to use the Disaster Recovery System, and provides procedures for completing various backup-related tasks and restore-related tasks. 7 CHAPTER 1 Disaster Recovery System Overview Disaster Recovery System, page 1 Supported Features and Components, page 2 System Requirements, page 2 Master Agent, page 4 Local Agents, page 4 Log In to Disaster Recovery System, page 5 Disaster Recovery System The Disaster Recovery System (DRS), which can be invoked from Cisco Unified Communications Manager Administration, or from any IM and Presence Service node, provides full data backup and restore capabilities for all servers in a Cisco Unified Communications Manager cluster. 8 Supported Features and Components Disaster Recovery System Overview The system automatically starts the Master Agent on the publisher node, and starts the Local Agent on all cluster nodes. 9 Disaster Recovery System Overview System Requirements versions of Cisco Unified Communications Manager. 10 Master Agent Disaster Recovery System Overview Titan Cisco does not support using the SFTP product freeftpd. 11 Disaster Recovery System Overview Log In to Disaster Recovery System Log In to Disaster Recovery System Use the following procedure to access the Disaster Recovery System on Cisco Unified Communications Manager (Unified Communications Manager) nodes, or on IM and Presence nodes. 21 CHAPTER 3 Restore Procedures Restore Quick Reference, page 15 Restore Scenarios, page 16 Restore s and Tips, page 16 Restore Node Or Cluster to Last Known Good Configuration, page 18 Restore Entire Cluster, page 20 Restore the First Node Only, page 21 Restore Subsequent Cluster Nodes, page 23 Restore Cluster in One Step After Publisher Rebuilds, page 23 Check Current Restore Job Status, page 25 Troubleshooting, page 26 Restore Quick Reference The following procedure provides a quick, high-level reference to the major steps, in chronological order, that you must perform to do a restore procedure by using the Disaster Recovery System.

For issues with third-party products that have not been certified through the Cisco Technology Developer Program process, contact the third-party vendor for support While a backup or restore is running, you cannot perform any OS Administration tasks, because Disaster Recovery System blocks all OS Administration requests by locking the platform API. If you are configuring backup and restore operations for IM and Presence nodes, select Navigation > IM and Presence Disaster Recovery System from the menu in the upper, right corner of Cisco Unified CM IM and Presence Administration window and click Go.
While a backup is running, you cannot perform any tasks in Cisco Unified OS Administration or Cisco Unified IM and Presence OS Administration because Disaster Recovery System locks the platform API to block all requests. Set Up Backup Devices Before you use the Disaster Recovery System, you must configure the locations where you want the backup files to be stored.
However, Disaster Recovery System does not block most CLI commands, because only the CLI-based upgrade commands use the Platform API locking package.
Purpose If you are already signed into the administration interface for the node, you must sign out of the application before you use the Disaster Recovery System. However, Disaster Recovery System does not block most CLI commands because only the CLI-based upgrade commands use the Platform API locking package. Procedure Step 1 Step 2 Step 3 Step 4 Log in to the Disaster Recovery System by using the same administrator username and password that you use for Cisco Unified OS Administration or IM and Presence OS Administration.
Configuration changes include any changes that you make in Cisco Unified Communications Manager Administration, Cisco Unified Serviceability, and the User Option windows. The Disaster Recovery System supports only matching software versions for restore operations. The Cisco implementation of TCP header compression is an adaptation of a program developed by the University of California, Berkeley (UCB) as part of UCB's public domain version of the UNIX operating system.
Step 2 Enter the same Administrator username and password that you use to access the Operating System Administration interface for the node. Tip If replication does not set up properly, use the "utils dbreplication rebuild" CLI command as described in the Command Line Interface Reference Guide for Cisco Unified Communications Solutions. When you perform a system data restoration, you can choose which nodes in the cluster you want to restore. Use the information in the following table to determine which SFTP server solution to use in your system. Master Agent Local Agents The system automatically starts the Master Agent service on each node of the cluster, but the Master Agent is functional only on the publisher node. For more information, see the Installing the CTL Client and Configuring the CTL Client procedures in the Cisco Unified Communications Manager Security Guide. The Disaster Recovery System includes the following capabilities: A user interface for performing backup and restore tasks.
Refer to the Command Line Interface Reference Guide for Cisco Unified Communications Solutions for more information.
Procedure Step 1 Step 2 Step 3 Log in to the Disaster Recovery System with the same administrator username and password that you use for Cisco Unified OS Administration or IM and Presence OS Administration. The Disaster Recovery System restores all nondatabase information from the backup file and pulls the latest database from the chosen subscriber node.


See the Cisco Prime Collaboration Deployment Admin Guide before you upgrade its version (SFTP) or Unified Communications Manager to ensure that the versions are compatible. The Disaster Recovery System uses an SSL-based communication between the Master Agent and the Local Agent for authentication and encryption of data between the Cisco Unified Communications Manager cluster nodes. Perform the following steps to manage backup schedules: Procedure Step 1 Step 2 Step 3 Step 4 Navigate to the Disaster Recovery System. If you are running a DRS restore on a SAML SSO enabled cluster with an OpenAM SSO backed up configuration, or on an OpenAM SSO enabled cluster with a SAML SSO backed up configuration, you will be logged out from the DRS GUI during restore. In order to resolve the hostname, you must first configure a DNS server on the publisher, or to navigate to System > Server on the publisher to add the subscriber for which the database is going to be restored from.
Log in to Cisco Unified Communications Manager Administration, choose Disaster Recovery System from the Navigation menu in the upper, right corner of the Cisco Unified Communications Manager Administration window, and click Go.
The Disaster Recovery System contains two key functions: Master Agent (MA) and Local Agent (LA).
If you are creating and editing backup schedules for IM and Presence nodes, select Navigation > IM and Presence Disaster Recovery System from the menu in the upper, right corner of Cisco Unified CM IM and Presence Administration window and click Go.
To check the status from the DRS GUI, log into the DRS GUI and navigate to Restore > Status. Procedure Step 1 Step 2 Step 3 Step 4 Log in to the Disaster Recovery System by using the same Administrator username and password that you use for Cisco Unified OS Administration or IM and Presence Administration. For more details, see the certificate management help pages in the Cisco Unified Communications Manager security guides. Log in to the Disaster Recovery System by using the same Administrator username and password that you use for Cisco Unified OS Administration. The Disaster Recovery System supports only matching versions of Cisco Unified Communications Manager for restore. For Cisco Unified CM IM and Presence, log in to the Disaster Recovery System by using the same Administrator username and password that you use for Cisco Unified CM IM and Presence OS Administration. Initially, only the publisher node is fully restored, but when you perform Step 15 and restore the subsequent cluster nodes, the Disaster Recovery System performs database replication and fully synchronizes all cluster node databases.
The Disaster Recovery System does not migrate data from Windows to Linux or from Linux to Linux. During the restore process, do not perform any tasks with Cisco Unified Communications Manager Administration or User Options. Procedure Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Log in to the Disaster Recovery System with the same Administrator username and password that you use for Cisco Unified OS Administration or IM and Presence OS Administration.
Depending on the size of your database and the components that you choose to restore, the system can require a few hours to restore. For information on data migration from a Windows-based platform to a Linux-based platform, see the Data Migration Assistant User Guide before following the steps in this procedure. After the restoration completes and the Percentage Complete field on the Restore Status window in the Disaster Recovery System shows 100 percent, restart the server.
A subscriber node can be added manually to the cluster in Cisco Unified Communications Manager Administration (System > Server). For more information on restarting, see the Cisco Unified Communications Operating System Administration Guide.
After the restoration completes and the Percentage Complete field on the Restore Status window in the Disaster Recovery System shows 100 percent, restart the server(s). When the restoration completes and the Percentage Complete field on the Restore Status window in the Disaster Recovery System shows 100 percent, restart the server.
