PostgreSQL
Chapter 25. Backup and Restore
Table of Contents
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.
There are three fundamentally different approaches to backing up PostgreSQL data:
-
SQL dump
-
File system level backup
-
Continuous archiving
Each has its own strengths and weaknesses; each is discussed in turn in the following sections.
