1 BACKUP & RECOVERY ARCHIVE REPLICATION RESOURCE NAGEMENT SEARCH Key Benefits Provides better RPO/RTOs for critical data, even for the largest datasets and databases. CommVault Simpana Software with SnapBackup Combining the Power and Ease of Simpana 8.0 with the Speed of Snapshots Single unified client view and index integrates the client backup and snapshot management and recovery capabilities into a single platform. Unified policy-based management from the client through snapshot and backup, across disk and tape. All snapshots are recovery-ready and do not have a performance penalty on recovery. Create multi-tier recovery-ready copies on second tier media from the initial snapshot copy without impacting production. Integrated data deduplication when the snapshots are copied to nearline or offline media. Automatic rules for maintenance tasks (ex. log management, snapshot aging, etc.) and single policy embedded in application or filesystem agents simplify management of backup and archival data. Reduces load on production server by running validation against secondary data copy. Enables organizations to retain data representing a longer production window on disk for longer periods. Revert to go back to a point-in-time or restore to copy back data from any tier. Full application recovery or individual, granular file recovery. The Business Challenge Companies of all sizes continue to struggle with managing data growth in production, as well as backup and archival data stores. At the same time, many applications increasingly rely on 24/7 access to business-critical data, drastically reducing the amount of time available to backup data and putting tremendous pressure on IT s ability to meet their SLA commitments. Many customers are looking to native arraybased snapshot capabilities from vendors such as EMC and NetApp to meet the need for backup speed. Some of these options require expensive additional storage for snapshots, while others are much more storage efficient but require more time to rebuild data upon restore. Inherently, snapshots enable customers to make much more frequent backups of their data. That very ability creates its own set of challenges as snapshot management can quickly become complex. Exponential increases in the number of snapshots/backups make it difficult to manage and enforce consistent backup policies or quickly locate specific backup data copies from among various storage tiers. Furthermore, snapshots are typically tied to the production storage array. Any failure of the storage array itself leads to complete data loss. Creating a second copy of the data from snapshots usually requires purchasing another storage system at considerable expense and replicating data to it. However, as soon as you copy the snapshot over, you break any links of the second copy with the production system. As a result, recovery from the second copy requires several manual steps before the data is available to the production system for recovery. Smart use of snapshot capabilities should ensure that better backup speeds don t also transfer the workload and complexity of managing myriad sets of snapshots to the central site and it shouldn t complicate application data recovery. Organizations want an approach that speeds backup and simplifies data management and recovery. The CommVault Simpana Software Solution CommVault SnapBackup, an integral part of Simpana software, dramatically improves your ability to meet your SLA backup commitments, without sacrificing the ability to meet your requirements for recovery point objectives (RPO) and recovery time objectives (RTO) on the backend. SnapBackup makes it much more feasible to increase the number of recovery points kept in all of your storage tiers. This helps ensure that you re able to greatly increase your disk-based retention periods and decrease data restore and recovery times across all tiers. SnapBackup is designed to work with native snapshot capabilities for even the largest of databases and applications such as Microsoft Exchange, SQL Server and Oracle. Simpana software combines the speed of snapshot backups with the speed of application-aware snapshot recovery from any storage tier, all from a singular management console that spans multiple vendors and data management architectures.

Diagram 1: Overview of the Migration and Recovery Process (showing creation of secondary data protection snapshots, migration to lower-cost storage tiers including tape, auxcopy for validation, and most importantly, multiple recovery options/points from multiple tiers). Fast and Simplified Data Backup, Management and Recovery The CommVault SnapBackup solution leverages native array-based snapshots using the nextgeneration data management capabilities in its Simpana software. Unlike traditional streaming backup methods that can take hours to complete, SnapBackup software quickly acquiesces the application or file system, triggers the arraybased snapshot and returns the system to a fully operational state within minutes. Critical applications are down for only a few minutes instead of hours with snapshots as fully recoverable as traditional backups. Snapshots are mounted on a proxy server and validated as part of a secondary process to ensure the snapshot is a valid application consistent recovery copy and readily available for recovery. Organizations can replace selective and infrequent backups with multiple recovery points throughout the day, reducing both RPO and RTO. This enables you to minimize the backup impact on production systems, while realizing faster fullfile and application recovery. Depending on your configuration, automatic rules for maintenance tasks (proxy validation, log management, snapshot aging) and a single embedded policy further simplify management. Administrators can select from full application recovery or individual, granular file recovery as their needs dictate, without the need for manual steps to make the data available to the application, database or file-system. Selective snapshots can be copied using a secondary copy process and a proxy server to create a storage array independent backup copy. This ensures that data is recoverable directly to the production system or application, even if the storage array itself is not available. Furthermore, you can create multiple copies of data across different tiers. Each tier is recovery ready, which means data can be recovered directly from any tier to the production system. Embedded global data deduplication ensures that the data in the secondary tiers is stored efficiently, enabling costeffective data retention. Simpana content-awareness means that data that has been deduplicated can still be recovered quickly and easily.

CommVault deduplication software eliminates all duplicate copies of backup and archive data managed within the guidelines of your Global Storage Policy, regardless of source, data type or platform. We do this using our content-aware and adjustable segment-based approach that delivers better deduplication ratios compared to other blockbased approaches. We also compare the digital signature of each segment against all the other segments of data in your global storage policy, maximizing deduplication across 100% of your backup and archive data. Combining client-based generation of hash signatures with integrated data compression and data encryption capabilities minimizes network bandwidth requirements and maximizes end-toend network speed and security that goes all the way from clients all the way to disk and tape-based storage tiers. With Simpana software, you can expand the use of data deduplication across all tiers of storage, including tape, without the need to rehydrate the data back into full form. Using our automated, policy-based approach, you can implement a hands-free approach to migrate and manage aging data quickly and efficiently. The migration is invisible to end-users, and ensures that the deduplicated data is brought back seamlessly directly from any storage tier. CommVault also combines our Shared Index/Catalog with our unique SILO Storage to track and retrieve just the data required, without the need for lengthy restores and searching through entire volumes of data. Deduplication With Simpana is Especially Helpful for: End-to-end elimination of duplicate data across multiple backup cycles, and across backup and archive data stores g Greater deduplication ratios.

4 Unified Recovery Management SnapBackup delivers on CommVault s vision for Unified Recovery Management, delivering data availability through an integrated, singular approach to data management. Unified Recovery Framework wraps snapshot backups with more efficient secondary tiered storage into a simplified recovery framework that aligns to your specific service levels. Our approach relies on consolidated policies and automation that makes management simple and easy, and point-in-time recovery that is transparent to the complexities of where the recovery data source. With the downtime of business critical applications kept to a minimum throughout the day, organizations realize increased productivity while reaping the benefits of rapid backup and recovery. CommVault Simpana SnapBackup software seamlessly automates snapshot technologies as a part of backup and restore, management requirements are minimal. Less time required to oversee backups directly translates to budget savings. Leveraged use of existing storage devices and storage efficiencies also helps reduce the need for additional infrastructure or added headcount, minimizing the impact on your IT budget. Key Features and Benefits Features Faster backups which utilize the speed and efficiency of the underlying HW snapshot engine Provides a hardware agnostic snapshot management framework Provides options to automatically proxy mount and validate the snapshot copy and properly manage any database transaction logs Offers the ability to blend snapshot and backup options to meet stricter recovery point objectives (RPO) Merges all copies into a seamless recovery copy continuum Provides seamless application recovery from any copy Benefits Enables more frequent recovery points to be used in protecting an application. Recovery Point Objective (RPO) is a measure of the time between each recovery point image. Employs a hardware agnostic framework that allows seamless transition across hardware platforms with maximum freedom in infrastructure planning and choice. Optional controls to direct custom post-snapshot operations, such as movement to tape, integrity checks, and so forth. Unlike full volume protection only, SnapBackup allows incremental log backups from snapshots. In many cases RPO/RTO conditions require a split strategy protecting the databases (every 6 hrs) and logs (every 15 minutes). SnapBackup supports this need with a pair of protection policies to meet more stringent RPOs. Logs need to be protected by capturing and moving a copy quickly off the production volumes to protect against loss. Rather than moving extraneous files that are not relevant to the logs, but are captured in the volume snapshot, the policy should be smart enough to identify and efficiently move only the only the relevant log/incremental data. This results in significant network, media and operational savings. Snapshot copy, backup copy and tape copy creation/management is merged into a seamless data copy lifecycle set. This allows for tiered data recovery copies based on a set of declining recovery performance requirements over time, while also meeting retention requirements. Application-level restore is available directly from any recovery copy across online, nearline or offline media. Provides copy management policies Each recovery copy is modeled as a standard data lifecycle copy within the Simpana to meet specialize retention and Storage Policy model. SnapBackup uses an innovative approach on the initial archive copy requirements snapshot to catalog it and treat it as a protection copy although the contents of the data reside in the snapshot, as compared to a more traditional backup file container. Manage from a single consolidated console a multi-site, multi-application, multi-storage infrastructure Provides centralized policy management, alerting and operational reporting across distributed sites and heterogeneous storage infrastructure.
