This document describes how to configure a backup server for Cisco Unified Communications Manager in your network.
Cisco recommends that you have knowledge of Cisco Unified Communications Manager.
The information in this document is based on Cisco Unified Communications Manager 5.x/6.x.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Refer to Cisco Technical Tips Conventions for more information on document conventions.
In order to configure a backup server for Cisco Unified Communications Manager, you must complete two tasks:
Set up an SFTP server.
Configure Cisco Unified Communications Manager for backup.
In order to back up data to a remote device on the network, you must have an SFTP server configured.
Cisco allows you to use any SFTP server product with applications that require SFTP access but recommends SFTP products that are certified with Cisco through the Cisco Technology Developer Partner program (CTDP). CTDP partners, such as GlobalSCAPE, certify their products with a specified version of Cisco Unified Communications Manager.
Refer to http://www.cisco.com/web/partners/index.html for information on which vendors certify their products with your version of Cisco Unified Communications Manager.
These SFTP servers are supported and recommended. You can use any one of these SFTP servers:
Complete these steps in order to setup an SFTP server on your machine:
Note: GlobalSCAPE's Secure FTP Server is used in this example.
Download and install GlobalSCAPE's Secure FTP Server software on the machine on which you want to setup an SFTP server.
Configure the necessary settings, such as site root folder and connection protocols settings, and start the service.
Complete these steps in order to configure your Cisco Unified Communications Manager for backup.
Log into the Disaster Recovery System of Cisco Unified Communications Manager.
Choose the Backup Device option from the Backup menu.
The Backup Device List window appears.
Click the Add New button in order to add a new backup device.
The Backup Device window appears.
Enter this Network Directory information in the Select Destination section of the Backup Device window, and assign a name for the backup device.
Server name—IP address of the SFTP server
Path name—Path name for the directory where you want to store the backup file
Note: In the Cisco Unified Communications Manager settings, you only need to specify the Path Name as ./ (not C:\).
User name—user created in the SFTP server
Password—password for this user
Choose the Manual Backup option from the Backup menu.
The Manual Backup window appears.
Select any one of the backup devices from the Device Name list, and select the features you want to backup.
Click the Start Backup button in order to start the backup process.
There is currently no verification procedure available for this configuration.
This section provides information you can use to troubleshoot your configuration.
When a user tries to configure Cisco Unified Communications Manager with Secure File Transfer Protocol (SFTP) for backup, the Update failed : Unable to access SFTP server . Please make sure the login credentials and path are correct. error message appears.
Complete these actions in order to resolve this issue.
Ensure there is no connectivity issue between the SFTP server and Cisco Unified Communications Manager.
Ensure the user name and password entered in the Network Directory section of Cisco Unified Communications Manager is the same as the SFTP server username and password.
Cisco Unified Communications Manager DRS backup fails with the linux OpenSSH based SFTP servers.
This problem occurs with CallManager version 7.0.1 and UC version 6.1 if a linux-based sftp server is used as a backup device. The 'add device' operation fails. The fix has been added to 7.x and later.
A better workaround is to download and install in any one of these SFTPs:
OpenSSH for Windows
Edit /etc/ssh/sshd_config (on OpenSSH based sftp server) to contain this line: PasswordAuthentication yes. This will enable tunneled clear text passwords.
