Machine
A machine, sometimes referred to as an agent, is a physical or virtual machine or server that
is protected by the AppAssure 5 Core. In the context of replication, a core may also be
referred to as a source core.
Management Roles
The AppAssure 5 Central Management Console introduces a new concept of management
roles which lets you divide administrative responsibility among trusted data and service
administrators as well as access control to support secure and efficient delegation of
administration.
Mountability
Exchange mountability is a corruption detection feature that alerts administrators of
potential failures and ensures that all data on the Exchange servers is recovered successfully
in the event of a failure.
Object File System
The AppAssure Scalable Object Store is an object file system component. It treats all data
blocks, from which snapshots are derived, as objects. It stores, retrieves, maintains, and
replicates these objects. It is designed to deliver scalable input and output (I/O) performance
in tandem with global data deduplication, encryption, and retention management. The
Object File System interfaces directly with industry standard storage technologies.
Passphrase
A passphrase is a key used in the encryption the data. If the passphrase is lost, data cannot
be recovered.
PowerShell Scripting
Windows PowerShell is a Microsoft .NET Framework-connected environment designed for
administrative automation. AppAssure 5 includes comprehensive client SDKs for PowerShell
scripting that enables administrators to automate the administration and management of
AppAssure 5 resources by the execution of commands either directly or through scripts.
Quorum
For a failover cluster, the number of elements that must be online for a given cluster to
continue running. The elements relevant in this context are cluster nodes. This term can also
refer to the quorum-capable resource selected to maintain the configuration data necessary
to recover the cluster. This data contains details of all of the changes that have been applied
to the cluster database. The quorum resource is generally accessible to other cluster
resources so that any cluster node has access to the most recent database changes. By
default there is only one quorum resource per server cluster. A particular quorum
configuration (settings for a failover cluster) determines the point at which too many failures
stop the cluster from running.
Recovery Assure
Recovery Assure technology is used to perform automated recovery testing and verification
of backups. It supports various file systems and servers.
Recovery Points
Recovery points are a collection of snapshots of various disk volumes. For example, C:, D:,
and E.
Remote Core
A remote core represents an AppAssure 5 Core that is accessed by a non-core machine by
way of the Local Mount Utility.
