Cisco Unity an integral component of the Cisco IP Communications system is a powerful unified communications solution that provides the advanced, convergence-based communication services your company needs on a platform that offers the utmost in reliability, scalability, and performance. The Cisco Unity server architecture is unified with your data network, minimizing installation, administration, and maintenance costs. Built on a platform that can scale to meet your organization's needs as it grows, Cisco Unity also uses streaming media and an intuitive browser-style system administration interface that makes life easier for the people who install and support your system, ultimately lowering your organization's total cost of ownership. BUILT FOR MIGRATION TO IP TELEPHONY Designed to exploit IP networks, Cisco Unity plays a central role in the migration of your telephony infrastructure from TDM to IP. IP networks are easy to deploy a comprehensive communications solution because you have a single network for both voice and data. Cisco Unity interoperates with your legacy voice-mail system and supports Copyright (c) 2004 VERITAS Software Corporation. All rights reserved.

both Cisco CallManager and leading traditional telephone systems to help you transition to IP telephony at your own pace and protects your existing infrastructure investments. In addition, Cisco Unity's integration with the Session Initiation Protocol (SIP) provides native support for SIP proxy servers, designated SIP phones and clients, and SIP-enabled access gateways, giving SIP users access to the full benefit Cisco Unity delivers. Cisco Unity complements the full range of IP Communications solutions by providing advanced capabilities for unifying data and voice communication. Also, because it is enabled by Cisco AVVID (Architecture for Voice, Video and Integrated Data) and designed for a converged network, Cisco Unity provides a solid foundation for rolling out future convergence-based communications services. SIMPLIFY ADMINISTRATION, REDUCE COSTS The components of Cisco Unity extend the power of Microsoft Exchange Server and Lotus Notes Domino server by eliminating the inefficiencies and the limitations imposed by multiple and integrated messaging systems, and simplifies access and management. Cisco Unity uses Microsoft Exchange or Lotus Notes Domino message store and directory services to unify system administration, collecting all messages into a single store and providing you with a single address directory service. By sharing a single directory with the data network, Cisco Unity eliminates redundant user account information required by various applications such as e-mail and voice-mail systems. Cisco Unity saves time in initial installation by importing the Microsoft Windows 2000 or Microsoft Exchange or Lotus Notes Domino accounts directory to automatically create subscriber lists. With the Cisco Unity, all messages are centrally stored, administered, and controlled, dramatically reducing the amount of time spent on support and maintenance, and minimizing the traffic on your LAN. At the same time, Cisco Unity also uses the Cisco Unity Message Repository (UMR) to safeguard message store integrity if Microsoft Exchange or Lotus Notes Domino goes offline. Cisco Unity UMR enables Cisco Unity to continue taking new voice messages when the e-mail system or network is offline. System subscribers can also retrieve these messages, minimizing service disruption. Cisco Unity takes full advantage of powerful Microsoft Exchange and Lotus Notes Domino features such as digital networking, automatic message replication, message rules, foldering, and inbox assistant support. Through Microsoft Exchange or Domino s e-mail gateway services, Cisco Unity can also work with e-mail clients that support Simple Mail Transfer Protocol (SMTP) or Multipurpose Internet Mail Extensions (MIME), Post Office Protocol 3 (POP3), and Internet Message Access Protocol 4 (IMAP4). AN EASY-TO-USE, BROWSER-STYLE INTERFACE Cisco Unity features an award-winning graphical interface that gets users operating as quickly as possible, resulting in greater productivity for your organization. Moreover, Cisco Unity simplifies system administration with its embedded Microsoft Internet Information Server (IIS), single message store, and single directory service, providing superior performance and reliability. In addition to housing data in a central store, administration tasks can be handled conveniently from a Web-based system administration console that IT staff can access from any networked PC using Internet Explorer. The Cisco Unity system administration console minimizes the complexity of Microsoft Windows 2000 using either Microsoft Exchange or Lotus Notes Domino so you do not have to be a Microsoft Certified Systems Engineer (MCSE) to administer the system. This interface integrates with Microsoft Windows 2000 through the use of snapin HTML, and allows Cisco Unity to be configured and monitored from anywhere on the Internet using Internet Explorer.

PROTECTING CISCO UNITY ENVIRONMENTS WITH VERITAS BACKUP EXEC AND VERITAS NETBACKUP AND BEST PRACTICES The following sections of this white paper present how to protect Cisco Unity Environments using either VERITAS Backup Exec or VERITAS NetBackup. Recommended best practices will be discussed. Please note that ALL Cisco Unity and VERITAS environments are often complex and unique. Cisco Unity and VERITAS Backup Exec and VERITAS NetBackup users should consult their respective product manuals before attempting any of the best practices recommended in this white paper. DATA STORAGE IN CISCO UNITY Cisco Unity can be configured for either Cisco Unity Unified Messaging or for Cisco Unity Voice Messaging. The operating system and application software underneath Cisco Unity environment is built using Microsoft Windows 2000 Server, MSDE 2000 (e.g. Microsoft SQL Server 2000), and popular messaging applications such as Microsoft Exchange or Lotus Notes Domino. Additional Cisco Unity requirements are as follows: Voice messages are stored in IBM Lotus Domino, Microsoft Exchange 2000, or Microsoft Exchange 5.5 All subscriber information is stored in a Microsoft MSDE or Microsoft SQL Server 2000 or Domino database Some subscriber information also appears in the IBM Lotus Domino Address Book, Microsoft Active Directory, or the Microsoft Exchange 5.5 Directory Data that appears in both the Microsoft SQL Server 2000 or Domino database and in the Address Book/Directory is automatically synchronized Messages from outside callers are temporarily stored on the Cisco Unity Server CHOOSING THE RIGHT DATA PROTECTION SOLUTION VERITAS Backup Exec and VERITAS NetBackup software are qualified data protection products for use with Cisco Unity.

Both documents are available on Cisco.com To access these document, please click Products & Services > Voice Software > Cisco Unity > Technical Details > System Requirements. The VERITAS data protection considerations for Cisco Unity, including the messaging environment of Microsoft Exchange or IBM Lotus Domino servers, are the same for protecting Microsoft Windows 2000, Microsoft SQL Server, and Microsoft Exchange or IBM Lotus Domino systems. Both VERITAS NetBackup and VERITAS Backup Exec protect Microsoft Exchange and Microsoft SQL Server and IBM Lotus Notes Domino. No additional VERITAS Software agents and options are required for the protection of the Cisco Unity environment. Additional information on how Cisco Unity stores data: Cisco Unity stores data in a Microsoft SQL Server or MSDE database. To protect this data, you need to use either VERITAS NetBackup for Microsoft SQL Server agent or the VERITAS Backup Exec Agent for Microsoft SQL Server. Both VERITAS products utilize Microsoft s SQL Server backup API s to protect database data while the databases are online and available. Microsoft Exchange or IBM Lotus Domino data backups that are a part of the Cisco Unity architecture require VERITAS agents for online backup. Both VERITAS NetBackup and VERITAS Backup Exec treat Microsoft Exchange and IBM Lotus Domino as a typical application, whether or not Cisco Unity is deployed in the user s environment. VERITAS client agents are used to protect the Windows 2000 Operating Environment and the special considerations for Registry (i.e. System State), Active Directory, and other file attributes. VERITAS products protect Windows machines as a typical Windows server, whether or not Cisco Unity is deployed in the user s environment. Caution: If you do not use the tested and approved VERITAS NetBackup or VERITAS Backup Exec agents and attempt to backup the application and data files, the backup will be invalid. Do not rely upon open file management software; this too will not work reliably for Cisco Unity environment data protection. VERITAS has designed and developed advanced application aware agents to protect complex applications like Cisco Unity, which improve the user s recovery point and recovery time objectives to meet their Cisco Unity environment s service level agreements for backup and recovery operations. By leveraging additional solutions in the VERITAS software portfolio, you improve your return on investment by reducing or eliminating downtime in the event of system or software failure.

HOW LONG WILL RESTORING DATA TAKE Data restoration performance is difficult to predict without specific configuration and environment insight. Both NetBackup and Backup Exec software are high-performance backup and recovery applications, and provide Copyright (c) 2004 VERITAS Software Corporation. All rights reserved.

functionality for performance optimization. The results for your environment will vary depending on how your environment is configured and how much data is being protected. A good approach to characterizing backup and recovery performance requires learning the general software architecture, how each agent component interacts with the protected system, while contrasting this to the actual volume of data being backed up. Other factors that may affect performance can include initial system sizing, backup design decisions, as well as the more easily understood interactions of tape drive, LAN performance, and CPU load. VERITAS Software provides specific product tuning recommendations within the product documentation and via technical bulletins. Managing recovery performance will require an understanding of your company s service level agreements for allowable system down time and required system recovery time objectives. Recovery Time Objective (RTO) for backup and recovery can typically be considered in the range of hours, as opposed to seconds with other technologies. RTO should be modeled by performing regular recovery and disaster recovery tests simulating real world data loss scenarios. Performing disaster recovery tests is the only way to ensure total readiness for any data loss event, where preparedness and execution is paramount. After the initial backup product environment is designed, installed, and tested, you should plan on making the time to include full and partial recovery tests, system replacement tests, and bare metal disaster recovery tests. VERITAS Backup Exec and VERITAS NetBackup For servers running Cisco Unity, a full restore using Backup Exec software could typically be performed in a few hours if required. This example may not take into consideration the messaging stores or other types of recovery. Your exact backup performance is dependent on many factors. For the restore of the dependent messaging environment, performance for recovery can vary significantly. For example, in a centralized Microsoft Exchange or IBM Lotus Domino message store model, there may be generally larger volumes of Unified message data, potentially across several Microsoft Exchange or IBM Lotus Domino servers. The first consideration for any recovery plan is to anticipate the specific type of data loss you might encounter, and the actions that will be required to recovery the necessary data in the quickest way possible. For example, will you be required to perform a full Microsoft Exchange or IBM Domino server message store recovery? Perhaps the system can be restored by a single application file or directory? Perhaps only a single user message mailbox or message needs to be recovered? The key to successful data protection management of the Cisco Unity environment will be to understand the application data well enough to determine the minimal recovery requirements, as well as how to perform these recoveries with the selected VERITS data protection product. Considerations for planning for a full message store is dependent on the message server architecture and message store size. Good planning limits the message store size to meet your company s recovery service level agreement. Additionally, smaller, more granular mailbox and message level recoveries are possible with a Microsoft Exchange message store. However, these recoveries will require multiple backup images, first for the information store, followed by the mailbox level backup. This extra time can affect the backup window and media/tape consumption. Familiarity with these procedures will enable faster recovery of the correct information requested for full recovery. End users should practice their Cisco Unity infrastructure recovery plan, including the consideration of Microsoft SQL Server table recovery and Microsoft Windows 2000 file and system state recovery. The Cisco Unity user should perform a pre-production or test system recovery prior to your Cisco Unity roll out. Copyright (c) 2004 VERITAS Software Corporation. All rights reserved.
