without waiting for a full restore to production storage. Users remain productive and IT departments reduce recovery
windows to meet today's increasingly stringent RTO and RPO service-level agreements.

Recovery Assure

AppAssure Recovery Assure enables you to perform automated recovery testing and verification of backups. It includes,
but is not limited to, file systems, Microsoft Exchange 2007 and 2010, and different versions of Microsoft SQL Server
2005, 2008, and 2008 R2. Recovery Assure provides 100 percent recoverability of applications and backups in virtual and
physical environments, and features a comprehensive integrity checking algorithm based on 256-bit SHA keys that
check the correctness of each disk block in the backup during archiving, replication, and data seeding operations. This
ensures that data corruption is identified early and prevents corrupted data blocks from being maintained or transferred
during the backup process.

Universal Recovery

Universal Recovery technology gives you unlimited machine restoration flexibility. You can restore your backups from
physical systems to virtual machines, virtual machines to virtual machines, virtual machines to physical systems, or
physical systems to physical systems, and carry out bare metal restores to dissimilar hardware. For example, P2V, V2V,
V2P, P2P, P2C, V2C, C2P, and C2V.
Universal Recovery technology also accelerates cross-platform moves among virtual machines. For example, moving
from VMware to Hyper-V or Hyper-V to VMware. It builds in application-level, item-level, and object-level recovery
(individual files, folders, e-mail, calendar items, databases, and applications). With AppAssure 5, you can recover or
export physical to cloud, or virtual to cloud.

True Global Deduplication

AppAssure 5 provides true global deduplication that dramatically reduces your physical disk capacity requirements by
offering space reduction ratios exceeding 50:1, while still meeting the data storage requirements. AppAssure True Scale
inline block-level compression and deduplication with line speed performance, along with built-in integrity checking,
prevents data corruption from affecting the quality of the backup and archiving processes.

AppAssure 5 True Scale Architecture

AppAssure 5 is built on AppAssure True Scale architecture. It leverages dynamic, multi-core pipeline architecture that is
optimized to consistently deliver line-speed performance for your enterprise environments. True Scale is designed from
the ground up to linearly scale and efficiently store and manage big data, and deliver RTOs and RPOs of minutes without
compromising performance. It comprises a purpose-built object and volume manager with integrated global
deduplication, compression, encryption, replication, and retention. The following diagram describes the AppAssure True
Scale architecture.
