Most people admit that backups are essential, though they also devote a very small amount of time to thinking about the topic.
The first recipe is about understanding and controlling crash recovery. You need to understand what happens if the database server crashes so that you can understand when you might need to perform a recover operation.
The next recipe is all about planning. That's really the best place to start before you perform backups.
The physical backup mechanisms here were initially written by Simon Riggs (one of the authors of this book) for PostgreSQL 8.0 in 2004, and have been supported by him ever since, now with increasing help from the community as its popularity grows. 2ndQuadrant has also been providing database recovery services since 2004, and regrettably, many people have needed them as a result of missing or damaged backups.
It is important...
