The AppAssure Agent is software installed on a physical or virtual machine that lets it be added to protection in the AppAssure Core.

The first backup transfer saved to the Core is called a base image snapshot. All data on all specified volumes (including the operating system, applications, and settings), are saved to the Core. For more information, see snapshot. C

A checksum is a function that creates blocks of data that are used for the purpose of detecting accidental errors that are created during transmission or storage.

See Windows failover cluster. cluster continuous replication (CCR) A non-shared storage failover cluster solution, that uses built-in asynchronous log shipping technology to create and maintain a copy of each storage group on a second server in a failover cluster. CCR is designed to be either a one or two data center solution, providing both high a [..]

An individual machine that is part of a Windows Failover cluster.

The Storage Networking Industry Association (SNIA) defines compression as the process of encoding data to reduce its size.

The AppAssure Core is the central component of the AppAssure architecture. The Core provides the essential services for backup, recovery, retention, replication, archiving, and management. In the context of replication, the Core is also called a source core. The source core is the originating core, while the target core is the destination (another [..]

A set of up to 16 Microsoft Exchange Server 2010 Mailbox servers that provide automatic, database-level recovery from a database, server, or network failure. DAGs use continuous replication and a subset of Windows failover clustering technologies to provide high availability and site resilience. Mailbox servers in a DAG monitor each other for failu [..]

Data is encrypted with the intent that it is only accessible to authorized users who have the appropriate decryption key. Data is encrypted using 256-bit AES in Cipher Block Chaining (CBC) mode. In CBC, each block of data is XORed with the previous ciphertext block before being encrypted, this way each new ciphertext block depends on all preceding [..]

The Storage Networking Industry Association (SNIA) defines data deduplication as the replacement of multiple copies of data—at variable levels of granularity—with references to a shared copy to save storage space or bandwidth. The AppAssure Volume Manager performs global data deduplication within a logical volume. The granularity level of deduplica [..]
