Backup software
backup software
tool, software
software for doing a backup, often included as part of the operating system.
backup software should provide ways to specify what files get backed up and to where. it may include its own scheduling function to automate the procedure or, preferably, work with generic scheduling facilities. it may include facilities for managing the backup media (e.g. maintaining an index of tapes) and for restoring files from backups.
examples are unix’s dump command and windows’s ntbackup.

- Backup rotation
backup rotation operating system any system for re-using backup media, e.g. magnetic tape. one extreme would be to use the same media for every backup (e.g. copy disk a to disk b), the other extreme would be to use new media every time. the trade-off is between the cost of buying and storing media and […]
- Backus-naur form
backus-naur form language, grammar (bnf, originally “backus normal form”) a formal metasyntax used to express context-free grammars. backus normal form was renamed backus-naur form at the suggestion of donald knuth. bnf is one of the most commonly used metasyntactic notations for specifying the syntax of programming languages, command sets, and the like. it is widely […]
- Backward analysis
backward -n-lysis theory an -n-lysis to determine properties of the inputs of a program from properties or context of the outputs. e.g. if the output of this function is needed then this argument is needed. compare forward -n-lysis. (1997-11-23)
- Backward and forward
toward the back or rear. with the back foremost. in the reverse of the usual or right way: counting backward from 100. toward the past: to look backward over one’s earlier mistakes. toward a less advanced state; retrogressively: since the overthrow of the president the country has moved steadily backward. directed toward the back or […]
- Backward chaining
backward chaining algorithm an algorithm for proving a goal by recursively breaking it down into sub-goals and trying to prove these until facts are reached. facts are goals with no sub-goals which are therefore always true. backward training is the program execution mechanism used by most logic programming language like prolog. opposite: forward chaining.
