Backup Definitions from Business Continuity to Dedicated

Business Continuity
The ability of an organisation to continue to function even after a disastrous event, accomplished through the deployment of redundant hardware and software, the use of fault tolerant systems, as well as a solid backup and recovery strategy.
Byte
A unit of storage capable of holding a single character. On almost all modern computers, a byte is equal to 8 bits. Large amounts of memory are indicated in terms of kilobytes (1,024 bytes), megabytes (1,048,576 bytes), and gigabytes (1,073,741,824 bytes).
Cache
A high-speed memory or storage device that helps reduce the time required to read and write data to a slower device, such as a hard drive.
Cloning
Cloning is a type of backup which allows users to copy the whole partition or disc to another partition or disc with all files and folders. If the partition is bootable, the cloned partition will become bootable too.
Compression
The process of reformatting data so it takes less space on your storage medium(s).
Connectivity
A device's ability to connect or link with other devices on the network.
Consolidated Storage
Consolidated storage connects multiple servers and/or workstations to a centralised array of hard disk drives. This type of storage setup is designed to result in higher availability, manageability, scalability and performance for the applications these servers support.
Cross-platform
The capability of software or hardware to run on different platforms i.e. an application that is compatible on Windows and Macintosh operating systems.
DAS (Direct Attached Storage)
DAS is storage that is directly connected to a server/workstation. This direct connection provides fast access to the data; however, storage is only accessible from that server/workstation. DAS includes the internally attached local disk drives or any other storage medium attached directly.
Data protection
Data protection is a complex of measures which are used to protect data from being erased, damaged or destroyed.
Data transfer rate
The speed at which data is transmitted from one device to another. Data transfer rates are often measured in megabits per second (Mbps) or megabytes per second (MBps).
Dedicated
A dedicated device has only one function i.e. a backup server which has no other jobs other than to backup data.
