Data Backup Glossary (Letter B)
A collection of data stored on (usually remote) non-volatile storage media for purposes of recovery in case the original copy of data is lost or becomes inaccessible; also called a backup copy. To be useful for recovery, a backup must be made by copying the source data image when it is in a consistent state.
An interval of time during which a set of data can be backed up without seriously affecting applications that use the data.
Backup and recovery transfer protocol used by the EVault® Agent.
A bare-metal restore (BMR) is a restore in which the backed up data is available in a form which allows one to restore a computer system from “bare metal”—meaning without any requirements as to previously installed software or operating system.
Formally called buffer-to-buffer credit (BBC) spoofing, and also called buffer-to-buffer credits, this technology effectively removes limitations on data throughput for long-distance transmissions in a Fibre Channel storage area network (SAN). Fibre Channel protocols usually limit the distance between the source and the destination network to within a few kilometers. Using buffer-to-buffer credits makes it possible to use offsite storage hundreds of kilometers away.
The ability of an organization to continue to function even after a disastrous event. Business continuity is accomplished through the deployment of redundant hardware and software, the use of fault tolerant systems, as well as a solid backup and recovery strategy.
Business continuity planning
Business continuity planning (BCP) covers both disaster recovery planning and business resumption planning. BCP is the preparation and testing of measures that protect business operations and also provide the means for the recovery of technologies in the event of any loss, damage, or failure of facilities
Business recovery team
A group of individuals responsible for maintaining the business recovery procedures and coordinating the recovery of business functions and processes. Also called a disaster recovery team.
Business recovery timeline
The chronological sequence of recovery activities, or critical path, that must be followed to resume an acceptable level of operations following a business interruption or outage. This timeline may range from minutes to weeks, depending upon the recovery requirements and methodology.
