Backtracking is an algorithmic-technique for solving problems recursively by trying to build a solution incrementally, one piece at a time, removing those. This slides gives a strong overview of backtracking algorithm. How it came and general approaches of the techniques. Also some well-known.

Backtracking is an algorithm for capturing some or all solutions to given computational issues, especially for constraint satisfaction issues.
Backtracking is considered an important technique to solve constraint satisfaction issues and puzzles. It is also considered a great technique for parsing and also forms the basis of many logic programming languages. Backtracking helps in solving an overall issue by finding a solution to the first backtrafking and then recursively attempting to resolve other sub-problems based on the solution of the first issue.
If the current issue cannot be resolved, the step is backtracked and the next possible solution is applied to previous steps, and then proceeds further. In fact, one of the key things in backtracking is recursion.
Backtracking – Wikipedia
It is also considered as a method of exhaustive search using divide and conquer. A backtracking algorithm ends when there are no more solutions to the first sub-problem. Backtracking is an algorithm which can help achieve implementation of nondeterminism. It takes a depth-first search of a given issue space.
It is used mostly in logic programming languages like Prolog.
Wherever backtracking can be applied, it is faster than the brute force technique, as it eliminates a large number of candidates with a single test. Definition – What does Backtracking mean? Techopedia explains Backtracking Backtracking helps in i an overall issue by finding a solution to the first sub-problem and then recursively attempting to resolve other sub-problems based on the solution of the first issue.
