What is the Disaster Recovery System?
The Disaster Recovery System (DRS), which can be invoked from Cisco Unified Presence Administration, provides full data backup and restore capabilities for all servers in a Cisco Unified Presence cluster. The Disaster Recovery System allows you to perform regularly scheduled automatic or user-invoked data backups. DRS supports only one backup schedule.
The Cisco Disaster Recovery System performs a cluster-level backup, which means that it collects backups for all servers in a Cisco Unified Presence cluster to a central location and archives the backup data to a physical storage device.
When performing a system data restoration, you can choose the nodes in the cluster that you want to restore.
The Disaster Recovery System includes the following capabilities:
•A user interface for performing backup and restore tasks.
•A distributed system architecture for performing backup and restore functions.
•Scheduled backups.
•Archive backups to a physical tape drive or remote SFTP server.
The Disaster Recovery System contains two key functions, Master Agent (MA) and Local Agent (LA). The Master Agent coordinates backup and restore activity with all the Local Agents.
The system automatically activates both the Master Agent and the Local Agent on all nodes in the cluster.
Quick-Reference Tables for Backup and Restore Procedures
The following tables provide a quick reference for the backup and restore procedures.
Backup Quick Reference
Table 1 provides a quick, high-level reference to the major steps, in chronological order, that you must perform to do a backup procedure by using the Disaster Recovery System.
Restore Quick Reference
Table 2 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.
Supported Features and Components
You can back up and restore the following features:
•CUP
•Database
Ensure that Cisco Unified Presence is running on all servers in the cluster.
How to Access the Disaster Recovery System
To access the Disaster Recovery System, choose Disaster Recover System from the Navigation menu in the upper, right corner of Cisco Unified Presence main window. Log in to the Disaster Recovery System by using the same Administrator username and password that you use for Platform Administration.
Note You set the Administrator username and password during Cisco Unified Presence installation, and you can change the Administrator password or set up a new Administrator account by using the Command Line Interface (CLI). Refer to the Cisco Unified Communications Operating System Administration Guide for more information.
Master Agent Duties and Activation
The system automatically activates the Master Agent on all nodes in the cluster, but only the Master Agent that runs on the publisher server is fully active.
Duties That the Master Agent Performs
The Master Agent (MA) performs the following duties:
•The MA stores systemwide component registration information.
•The MA maintains a complete set of scheduled tasks in theCisco Unified Presence database. When it receives updates from the user interface, the MA sends executable tasks to the applicable Local Agents, as scheduled. (Local Agents execute immediate-backup tasks without delay.)
•You access the MA through the Disaster Recovery System user interface to perform activities such as scheduling backups, adding a new backup task for a specific server or a defined cluster, updating or reviewing an existing entry, displaying status of executed tasks, and performing system restoration.
•The MA stores backup sets on a locally attached tape drive or a remote network location.
Local Agents
Ensure each server in a Cisco Unified Presence cluster, including the server that contains the Master Agent, has its own Local Agent to perform backup and restore functions for its server.
Note By default, the system activates a Local Agent automatically on each node of the cluster.
Duties That Local Agents Perform
The Local Agent runs backup and restore scripts on each node in the cluster.
Adding Backup Devices
Before using the Disaster Recover System, you must configure the locations where you want the backup files to be stored. You can configure up to 10 backup devices. Perform the following steps to configure backup devices.
Procedure
Step 1 To navigate to the Disaster Recovery System, choose Disaster Recovery System from the Navigation menu in the upper, right corner of the Cisco Unified Presence main window and click Go.
The Disaster Recovery System Logon window displays.
Note If you are already logged into Cisco Unified Presence Administration, you must log out of that application before you choose Disaster Recovery System.
Step 2 Log in to the Disaster Recovery System by using the same Administrator username and password that you use for the Cisco Unified Operating System.
Step 3 Navigate to Backup > Backup Device. The Backup Device List window displays.
Step 4 To configure a new backup device, click Add New.
The Backup Device window displays.
Step 5 Enter the backup device name in the Backup device name field.
Step 6 Choose one of the following backup devices and enter the appropriate field values in the Select Destination area:
•Tape Device—Stores the backup file on a locally attached tape drive. Choose the appropriate tape device from the list.
Note You cannot span tapes or store more than one backup per tape.
•Network Directory—Stores the backup file on a networked drive that is accessed through an SFTP connection. Enter the following required information:
–Server name: Name or IP address of the network server
–Path name: Path name for the directory where you want to store the backup file
–User name: Valid username for an account on the remote system
–Password: Valid password for the account on the remote system
–Number of backups to store on Network Directory: The number of backups to store on this network directory.
Note Ensure you have access to an SFTP server to configure a network storage location. The SFTP path must exist prior to the backup. The account that you use to access the SFTP server must have write permission for the selected path.
Step 7 To update these settings, click Save.
Note For network directory backups, after you click the Save button, the DRS Master Agent will validate the selected SFTP server. If the user name, password, server name, or directory path is invalid, the save will fail.
Creating and Editing Backup Schedules
You can create up to 10 backup schedules. Each backup schedule has its own set of properties, including a schedule for automatic backups, the set of features to back up, and a storage location.

Step 10 To update these settings, click Save.
Step 11 To enable the schedule, click Enable Schedule.
The next backup occurs automatically at the time that you set.
Note Ensure that all servers in the cluster are running the same version of Cisco Unified Presence and are reachable through the network. Servers that are not running at the time of the scheduled backup will not be backed up.
