As with everything that contains valuable data, PostgreSQL databases should be backed up regularly. While the procedure is essentially simple, it is important to have a clear understanding of the underlying techniques and assumptions.

SQL dump
File system level backup
Continuous archiving
Each has its own strengths and weaknesses. Each is discussed in turn below.
