-- RecoveryDirector First to Integrate Multi-vendor Snapshot and Backup into Single Workflow with One-step Recovery --

'CommVault Simplifies Recovery Management in Tiered Storage Environments

Oceanport, NJ — June 7, 2006 — Companies seeking to maximize value from investments in tiered storage have focused on establishing data protection and archive tiers, but the real win may lie with near-line recovery tiers and their potential to dramatically improve Recovery Time and Recovery Point Objective (RTO/RPO) service levels. CommVault®, a leading provider of Unified Data Management™ solutions, today announced an advance in data recovery management with the availability of breakthrough features for its QiNetix 6.1 Unified Data Management suite. The new feature set, called RecoveryDirector 6.1, combines certain functionality of the QuickRecovery and Galaxy Backup and Recovery software products, thereby enabling storage administrators to simply and seamlessly manage snapshot and backup data across the continuum of protection, recovery and archive tiers.

With RecoveryDirector, enterprises with storage area networks (SANs) will be able to increase the business value of tiered storage by creating online 'recovery images' that extend traditional backup methods and expand data protection capabilities. RecoveryDirector extends the benefits of QuickRecovery by enabling storage administrators to simplify recovery of data from multiple recovery points, reduce or eliminate backup windows, and improve RTO/RPO service levels.

RecoveryDirector's features bring the power of Unified Data Management to high-availability SAN environments with multiple tiers of data under management, providing a single view of the data protection environment and a set of common management policies that enable administrators to move data appropriately via workflows and policies. Data can be recovered quickly based on its value to the business, ensuring quick recovery from any tier of storage when problems occur. Moving beyond the Recovery Point data protection offered by QuickRecovery, RecoveryDirector adds sequencing, workflow and policy management that unifies data protection at all levels of an enterprise.

Single Workflow, One-step Recovery
Integrating CommVault ProxyHost, Image, QuickRecovery and QSnap components, CommVault RecoveryDirector combines backup and snapshot management into a logical workflow. With this capability, users can easily manage concurrent multiple point-in-time snapshots and backup sets, improve resource utilization and eliminate duplicate operations.

For enterprises seeking to simplify use of device-embedded snapshot capabilities, RecoveryDirector manages a wide variety of snapshot technologies including those offered by Data Domain, Dell, EMC, HDS, HP, NetApp, Xiotech and others. RecoveryDirector simplifies and automates the process of creating snapshot images and online recovery volumes for immediate recovery from data loss, large database corruption and e-mail virus attacks.

"As enterprises invest in storage tiers, particularly mid-range tiers, we believe IT should think about the value of establishing a recovery tier to increase the business value of data protection and archive tiers," said Arun Taneja, founder and principal analyst, Taneja Group. "CommVault's RecoveryDirector solution includes support for recovery tiers that will enable IT managers to shift data management efforts away from a narrow focus on backup process to the more vital issue of managing data to ensure recovery."

"We use CommVault QuickRecovery to snap and replicate images supporting our Exchange and Windows file system servers," states Colin Harford at University of Alberta Human Resources. Opened in 1908 as a board-governed public institution, the University of Alberta has grown to be one of Canada's foremost research-intensive universities serving more than 35,500 students in more than 200 undergraduate programs and 170 graduate programs. "CommVault makes it easy for us to keep point-in-time protection images online in our SAN. We use those images for our disaster recovery with CommVault Galaxy, so that our in-house production systems are not impacted."

"Hitachi Data Systems is pleased to work with CommVault to offer RecoveryDirector 6.1 to users of our backup and recovery solutions," said Jack Domme, senior vice president, global solutions, strategy and development, Hitachi Data Systems. "RecoveryDirector adds critical enterprise recovery management capability for users who rely on snapshot technology including Hitachi TrueCopy™ Remote Replication, Hitachi ShadowImage™ In-System Replication and QuickShadow capabilities to enable non-disruptive backups and quick recovery in SAN environments."

"NetApp innovated and introduced NetApp® Snapshot™ technology to the storage industry over 10 years ago. Customers trust NetApp Snapshot technology for all their networked storage environments, including both SAN and NAS. SnapVault® is an innovative enhancement to NetApp Snapshot technology, designed for backing up remote office environments," said Patrick Rogers, vice president of Products and Alliances at Network Appliance, Inc. "CommVault RecoveryDirector provides a simple and streamlined way to leverage and control these Snapshot capabilities to accelerate our customers' recovery operations and simplify their IT procedures."
