1. Introduction to Postgres Incremental Backups

In today's digital era, data has become an essential asset for businesses worldwide. Any disruption to this valuable resource could result in enormous losses, both financially and operationally. One of the most effective strategies to prevent data loss and ensure business continuity is to implement a reliable backup and recovery solution.

PostgreSQL is one of the most popular open-source relational database management systems (RDBMS), widely used by organizations for its flexibility, reliability, and extensive feature set. Like any database, however, it is essential to safeguard PostgreSQL data against unforeseen incidents, such as hardware failures, software bugs, or even human error. This guide delves deep into the world of PostgreSQL incremental backups, helping you master the art of efficiently protecting your data.

2. An Overview of Different Types of Backups

There are three primary types of database backups: full, differential, and incremental. Each type serves a specific purpose and has its advantages and disadvantages.

Full Backups

A full backup consists of a complete copy of the database at a specific point in time. Full backups are the most comprehensive form of backup, as they contain all data, including system catalogs, user data, and index data. However, they can be time-consuming, resource-intensive, and require significant storage space.

Differential Backups

Differential backups only contain the changes made to the database since the last full backup. They are faster and require less storage space than full backups but may still take longer to restore as multiple differential backups may need to be applied sequentially.

Incremental Backups

Incremental backups store only the changes made to the database since the last backup, whether full or incremental. This type of backup minimizes storage space requirements, reduces backup time, and expedites the restoration process.

3. Why Choose Incremental Backups?

Incremental backups offer several benefits, making them an attractive option for organizations striving to optimize their data protection strategies:

  • Time-efficient: Incremental backups require less time to complete compared to full and differential backups.
  • Space-efficient: They consume less storage space since only the changes made since the last backup are stored.
  • Flexible: Incremental backups can be utilized in combination with full and differential backups to design a customized backup strategy tailored to specific needs.

4. Prerequisites for Postgres Incremental Backup

Before diving into the setup process for Postgres incremental backups, ensure that you have the following prerequisites in place:

  1. Administrator access to your PostgreSQL server.
  2. A valid PostgreSQL installation, with the pg_basebackup and pg_receivewal utilities installed.
  3. Adequate storage space on your backup server for storing the incremental backup files.

5. Setting Up Postgres Incremental Backups

Setting up Postgres incremental backups involves three main steps: configuring the PostgreSQL server, creating a base backup, and setting up incremental backups with pg_receivewal.

Step 1: Configure the PostgreSQL Server

Edit the postgresql.conf configuration file to enable WAL (Write-ahead Logging) archiving and specify the appropriate parameters:

wal_level = replica
archive_mode = on
archive_command = 'test ! -f /path/to/archive/%f && cp %p /path/to/archive/%f'

Also, consider setting the archive_timeout parameter to control the frequency of WAL file generation.

Step 2: Create a Base Backup

Execute the pg_basebackup utility to create a base backup:

pg_basebackup -h [host] -U [user] -D /path/to/base/backup -P -Ft -Xs -R -z

The options used in this command perform the following functions:

  • -D: Specifies the target directory for the base backup.
  • -P: Displays progress information during the backup operation.
  • -Ft: Generates a tar-format backup.
  • -Xs: Includes WAL files required for archive recovery in the backup.
  • -R: Creates a recovery.conf file to enable point-in-time recovery.
  • -z: Compresses the backup for storage efficiency.

Step 3: Set Up Incremental Backups with pg_receivewal

The pg_receivewal utility can be used to implement incremental backups:

pg_receivewal -h [host] -U [user] -D /path/to/incremental/backup -S /path/to/slot_name

This command streams and stores the WAL files to the specified directory, providing a continuous incremental backup of the database.

6. Restoration Process: Bringing your Data Back to Life

To restore your PostgreSQL data, follow these steps:

  1. Stop the PostgreSQL server and clear the data directory.
  2. Extract the base backup to the server's data directory.
  3. Apply the incremental backups using pg_receivewal or the pg_wal directory (depending on your backup strategy).
