Target Core
The target core, which is sometimes referred to as replica core, is the AppAssure 5 Core
receiving the replicated data from the source core.
Target Replica Machine
The instance of a protected machine on a target core is known as the target agent or replica
agent.
Transport Layer Security
Transport Layer Security (TLS) is a modern cryptographic network protocol designed to
ensure communication security over the Internet. This protocol, defined by the Internet
Engineering Task Force, is the successor to Secure Sockets Layer (SSL). The SSL term is still
generally used, and the protocols are interoperable (a TLS client can downgrade to
communicate to an SSL server).
True Scale™
True Scale is the scalable architecture of AppAssure 5.
Universal Recovery
AppAssure Universal Recovery technology provides unlimited machine restoration
flexibility. It enables you to perform monolithic recovery to- and from- any physical or
virtual platform of your choice as well as incremental recovery updates to virtual machines
from any physical or virtual source. It also lets you perform application-level, item-level, and
object-level recovery of individual files, folders, email, calendar items, databases, and
applications.
Virtual Standby
Virtual Standby is a physical-to-virtual (P2V) process that creates a clone virtual machine of
a protected machine or agent. A Virtual Standby can be created using an ad-hoc or a
continuous update export process. A Virtual Standby created using a continuous update is
incrementally updated after every snapshot captured from the source agent.
Volume Manager
The AppAssure 5 Volume Manager manages objects and then stores and presents them as
a logical volume. It leverages dynamic pipeline architecture to deliver TruScale™ scalability,
parallelism, and asynchronous input-and-output (I/O) model for high throughput with
minimal I/O latency.
White Labeling
AppAssure 5 provides the ability for providers of backup and disaster recovery services to
white label or re-brand AppAssure 5 with their own identity; and then sell or distribute it as
their own product or service.
Windows Failover Cluster
A group of independent computers that work together to increase the availability of
applications and services. The clustered servers (called nodes) are connected by physical
cables and by software. If one of the cluster nodes fails, another node begins to provide
service (a process known as failover). Users experience a minimum of disruptions in service.
AppAssure 5 supports the protection of a number of SQL Server and Exchange Server cluster
types.
