Recovery Techniques for Database Systems

Joost Verhofstad

One-line summary: This paper presents seven techniques commonly used for recovery in database systems.

Overview/Main Points


Recovery from failure is a critical factor in databases. In case of disaster, it is very important that as much as possible (if not everything) is recovered. This paper surveys the methods that we in use at the time for data recovery.


This paper contained excess verbosity. This paper could and should have been shorter and more concise than it was. The examples especially could have been clearer and less involved. It might have been more valuable to give a single complete view of several systems than to detail the migration of (now obsolete) systems over time. The terminology and categories presented at the beginning were useful and potentially timeless, which the example were not.
