What is the Disaster Recovery System?
The Disaster Recovery System (DRS), which can be invoked from Cisco Unified Communications Manager Administration, provides full data backup and restore capabilities. The Disaster Recovery System allows you to perform regularly scheduled automatic or user-invoked data backups.
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 Local Agents.
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.
Note The Disaster Recovery System does not migrate data from Windows to Linux or from Linux to Linux. A restore must run on the same product version as the backup. For information on data migration from a Windows-based platform to a Linux-based platform, refer to the Data Migration Assistant User Guide before following the steps in Table 1.
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.
System Requirements
Revised August 26, 2008
Make sure that Cisco Unified Communications Manager is running
To back up data to a remote device on the network, you must have an SFTP server configured. The following SFTP servers are supported and recommended, but you may use any SFTP server:
•Open SSH (for Unix systems)
•Cygwin (refer to http://sshwindows.sourceforge.net/)
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 Communications Manager Administration window. Log in to the Disaster Recovery System by using the same Administrator username and password that you use for Cisco Unified Communications Operating System Administration.
Note You set the Administrator username and password during Cisco Unified Communications Manager installation, and you can change the Administrator password or set up a new Administrator account by using the Command Line Interface (CLI). Refer to theCisco Unified Communications Operating System Administration Guide for more information.
Master Agent Duties and Activation
The system automatically activates the Master Agent (MA) on the server.
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 the 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 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.
•The MA stores backup data on a locally attached tape drive or a remote network location.
Local Agents
The server also has a Local Agent to perform backup and restore functions.
Duties That Local Agents Perform
The Local Agent runs backup and restore scripts on the server.
Managing Backup Devices
Before using the Disaster Recovery 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 Navigate to the Disaster Recovery System. 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 Logon window displays.
Step 2 Log in to the Disaster Recovery System by using the same Administrator username and password that you use for Cisco Unified Communications Operating System Administration.
Step 3 Navigate to Backup>Backup Device. The Backup Device List window displays.
Step 4 To configure a new backup device, click Add New.
Step 5 To edit a backup device, select it in the Backup Device list, then click Edit Selected.
The Backup Device window displays.
Step 6 Enter the backup device name in the Backup device name field.
Note The backup device name may contain only alpha numeric characters, spaces ( ), dashes (-) and underscores (_). No other characters are allowed.
Step 7 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 You must have access to an SFTP server to configure a network storage location. The SFTP path must exist prior to the backup. The account that is used to access the SFTP server must have write permission for the selected path.
Step 8 To update these settings, click Save.
Note After you click the Save button, the DRS Master Agent validates the selected backup device. If the user name, password, server name, or directory path is invalid, the save will fail.
Step 9 To delete a backup device, select it in the Backup Device list, then click Delete Selected.
Note You cannot delete a backup device that is configured as the backup device in a backup schedule.
