The Business Challenge Managing data at remote sites can be costly, time consuming and inefficient. By some estimates, remote office data management accounts for 40 60% of a typical enterprise IT budget. As the costs of managing remote office data continue to rise, IT administrators must look for cost-effective solutions that simplify administration, increase data availability and improve disaster recovery preparedness. The CommVault Solution CommVault Continuous Data Replicator (CDR) is a host-based, asynchronous replication solution that delivers Continuous Data Protection (near- CDP) for Windows, Linux and UNIX environments. CDR centralizes the management of remote office data, provides fast, cost-effective disaster recovery and increases data availability. CDR minimizes bandwidth consumption by continuously capturing and replicating file changes at the byte level. It also optimizes available network resources by allowing administrators to throttle network bandwidth. CDR increases recoverability by providing unique, application-consistent snapshots in addition to the primary replica. As part of the CommVault suite of software, CDR replication can be managed along with backup, recovery and archive from a single Unified Console. Centralize Remote Office Data Managing remote office data has traditionally been expensive and problematic. Maintaining backup software and infrastructure in remote offices is costly; distracting remote office personnel with backup and tape rotation tasks is disruptive; paying an offsite services company to drive to each remote office and collect tapes is inefficient. What if instead of protecting data remotely you could centralize it and protect it with your data center infrastructure? Continuous Data Replicator delivers real-time replication of Windows, Linux and UNIX data, enabling you to cost-effectively centralize remote office backup and recovery. By using a single infrastructure of backup software and devices, CDR lets you efficiently leverage a single trained team of backup and recovery specialists and provide a central collection point for tape rotation. Its unique feature set ensures data coherency, recovery and ease-of-management. Configuration of replication pairs within CDR makes it easy to establish a fan-in, many-toone configuration, where multiple remote office locations replicate to a central location. This centralized approach helps reduce costs and increases the reliability of backup and recovery operations.

2 Key Capabilities Easy, centralized management of operations Provides the industry s only graphical user interface from which to easily create, track, administer and manage replication along with backup, recovery and archive using a single policy engine. Unique Application Recovery Points Captures point-intime snapshot-based images of replicated data and offers special application integration for Microsoft Exchange and SQL Server data. This maintains application integrity and provides consistent recovery images behind the replica. Smart synchronization technology Enables quick synchronization of your replica following a network outage, without the overhead of hefty check-sum or other networkintensive comparisons between the source and target. Online replica of entire SQL Server or Exchange Information Store database Improves recoverability by enabling administrators to utilize the replica in a standby configuration or copy back any of the point-in-time recovery points to any server within the environment. Point-and-click reporting Provides a central location where administrators can view or schedule color-coded backup and replication reporting for easy management. Expanded platform support Extends remote office data protection to Windows, Windows-based Clusters, and AIX servers running on 32 or 64-bit editions as well as 32-bit Linux servers. Scheduled bandwidth throttling Optimizes available network resources by allowing administrators to match replication needs to available bandwidth. A many-to-one configuration is typically used in a remote office scenario. Enhance Disaster Recovery Moving data offsite is the accepted method for ensuring recovery following a site disaster or outage. However, you are only as good as your last backup and sometimes losing the data that has changed since the last backup can materially disrupt your business. What if you could protect your company s critical data with a second copy that is current up-tothe-instant rather than your last backup? Continuous Data Replicator enables off-site protection. Real-time replication creates a second copy of your data at a remote location as it is written to disk at the production site. In the event of a site outage, you have a second copy of your data online, current up-to-the-instant of the disaster and immediately available for use. CDR real-time replication of data can be deployed in a one-to-many configuration. This gives maximum flexibility to leverage your existing sites for disaster recovery purposes or consolidate data at a dedicated off-site disaster recovery location. A one-to-many configuration is typically used in a disaster recovery scenario. Unify Management and Reporting Introduction of new applications and system management tools into an organization requires careful planning and often leads to lengthy efforts to justify the cost and time associated with learning, deploying and managing new software. What if rather than needing to manage yet another point product you could have a single management interface and seamless integration between data replication and backup software? The foundation of the CommVault Singular Information Management suite of software is the Common Technology Engine, or CTE. The CTE provides common services for every data management application in the suite. So you can run replication and backup using the same interface and leveraging the same back-end hardware. This expands functionality and allows businesses to leverage existing skill sets. For example, CommVault Galaxy Backup & Recovery can make backup copies off of CDR replicas or snapshot-based Recovery Points. Because they use the same policy engine, CommVault Galaxy software can restore backup copies directly to the original source.

3 Maintain the Integrity of Your Applications The continued success of most enterprises relies on the integrity of data stored in database and servers. Unforeseen events like power surges, hardware failures and network outages can easily interrupt the transfer of data in your organization and leave you guessing as to the state of your critical data. What if you didn t have to guess at the state of the replicated data because consistency points were embedded in the replication stream? Continuous Data Replicator maintains the integrity of your application data for Microsoft Exchange, SQL Server and Oracle data by creating consistent Recovery Points. CDR marks the replication stream at points that are known good states. CDR leverages these consistency points to create application-consistent pointin-time snapshots (recovery points). Recovery Point snapshots provide an additional layer of protection against viruses and corruption, enabling you to restore Microsoft Exchange and SQL Server databases with confidence. Manage replication pairs from source path, destination path, state and applications Automatically identifies the application data source for replication Integrate Data Management and Protection Replication is only the first step in a comprehensive data protection strategy. Once replicated to a remote host, your data needs to be protected and managed through its lifecycle. CDR is fully integrated with CommVault Galaxy backup to automatically create backup sets of replicas at scheduled intervals based on policies you define. Additionally, when used in conjunction with CommVault Data Archiver, CDR can provide efficient disaster recovery and remote office protection of migrated data without requiring offline files to be recalled. Maintain Uninterrupted Data Consistency When replicating data over wide area networks, network link failures can and will happen. The ability to gracefully recover from link failure is a key factor in protecting your remote office data. When links do fail, many replication solutions require the administrator to perform manual comparisons of source and replica data to determine what data was modified during the network outage. What if you could recover from network failures without performing manual data comparisons? CDR ensures that you can quickly return to a production state by carefully tracking all change activity during the network interruption and automatically bringing the replica up to a consistent state when network services are restored. CDR helps you deliver the high service levels critical to maintaining business continuity. Improve RTO/RPO Service Levels When a virus attack or data corruption occurs, your current best option for recovery probably includes a restore process and depending on the size of your database, this may take hours and even days. In most environments, a lengthy recovery process and loss of data can disrupt business operations and significantly impact the bottom line. What if you could reduce your recovery time from days or hours to minutes and eliminate data loss and user impact? CDR improves recovery times and helps meet stringent recovery point objectives. CDR s realtime replicas and Recovery Point snapshots allow you to quickly and reliably recover remote Windows file system data as well as Microsoft Exchange, SQL Server and Oracle databases. 3

4 Both replicas and Recovery Points can be mounted for granular file selection and instant recovery without administrative assistance. And since they are inherently consistent with their applications, you can use them to make backup copies to any client system without impacting production systems or data. How it Works CDR provides continuous data protection by capturing data written by a server, onto an attached disk (internal or external) in real time. Any disk that is mountable by the server can be seen and protected with CDR. CDR duplicates the I/O stream as it is written to the disk, and then sends the data as fast as possible across the network to a second server system. Continuous data protection can also be leveraged in a Windowsbased clustered environment for easy fail-over. CDR is also deployed on the second server to capture the replicated I/O stream and then to apply that I/O stream to a duplicate copy of the data. This creates an up-to-date replica. CDR inserts consistency markers in the replication log to enable the creation of application-consistent recovery point snapshots at the destination. CDR can maintain and dial back to multiple pointin-time snapshots for fast application recovery.
