Glossary
Active Directory: A centralized directory service system produced by Microsoft that automates
network management of user data, security and resources, and enables interoperation with
other directories. Active Directory is designed especially for distributed networking
environments.
Advanced Encryption Standard (AES): A recent U.S. government encryption standard
designed as the replacement for the aging Data Encryption Standard (DES).
Agent: A server, laptop or PC to be backed up using SonicWALL CDP.
Agent Service: A SonicWALL CDP software installed automatically on agents with Agent User
Interface software. Agent Service communicates with the SonicWALL CDP appliance.
Agent User Interface: A SonicWALL CDP software installed on agents. Agent User Interface
is a user interface for users of SonicWALL CDP agents that allows data backup and recovery
configuration, as administered by the SonicWALL CDP Web Management Interface.
Backup Task: A defined File Set and Schedule are combined into a Backup Task for execution.
Without a Backup Task, no backups will occur.
CDP Backup Method: One method of configuring file and folder backups on agents. The CDP
method corresponds to the method used in the SonicWALL CDP 5.1 and earlier releases. Files
are backed up individually rather than as a File Set, with new revisions created continuously as
changes occur, up to a set limit of revisions.
Data De-duplication: The process used by SonicWALL CDP to back up only the blocks of data
that have changed since the last scheduled backup. Metadata is used to map the changes
between different revisions so that any revision can be restored correctly.
Domain Name System/Service (DNS): An Internet service that translates domain names into
IP addresses. Because domain names are alphabetic, they're easier to remember. The internet
however, is really based on IP addresses. Every time you use a domain, therefore, a DNS
service must translate the name into the corresponding IP addresses.
Downstream CDP appliance: A local CDP appliance on your LAN.
Dynamic Host Configuration Protocol (DHCP): A Protocol for assigning dynamic IP
addresses to devices on a network. With dynamic addressing, a device can have a different IP
address every time it connects to the network. In some systems, the device's IP address can
even change while it is still connected. DHCP also supports a mix of static and dynamic IP
addresses.
Dynamic addressing simplifies network administration because the software keeps track of IP
addresses rather than requiring an administrator to manage the task. This means that a new
computer can be added to a network without the hassle of manually assigning it a unique IP
address. Many Internet Service Providers (ISPs) use dynamic IP addressing for dial-up users.
Web Management Interface: A SonicWALL CDP software installed on the SonicWALL CDP
administrator's computer.
