1. Introduction

In any business, managing and maintaining databases is critical for its survival. As important as it is to ensure high-availability, optimal performance, and security, one cannot overlook the necessity for regular data backups. An effective backup solution should address various factors, such as ease of use, storage efficiency, speed, and recovery reliability.

In this guide, we will compare popular Postgres backup tools, evaluate their strengths and weaknesses, and provide insights to help you choose the right solution for your needs. We will also highlight a practical solution - Slik Protect - that significantly simplifies your PostgreSQL backup process.

2. Built-in PostgreSQL Backup Tools

PostgreSQL includes built-in tools to perform data backups, and in this section, we'll discuss two of the most commonly used options: pg_dump and pg_basebackup.

2.1. pg_dump

pg_dump is a built-in utility that allows you to create a logical backup of your PostgreSQL database. With pg_dump, you can back up a single database, which results in a plain-text, tar, or custom-format output file.

Pros of pg_dump

• Simple to use
• Ideal for small-scale databases
• Can selectively back up specific database objects
• Can be restored using pg_restore or psql, depending on the chosen output format

Cons of pg_dump

• Not suitable for large-scale databases
• Slower backup and restore process
• Does not include server-related configuration files in the backup

2.2. pg_basebackup

pg_basebackup is another built-in utility in PostgreSQL that allows you to create a physical backup of the entire database cluster. This type of backup includes all the necessary files needed to restore the entire database instance, including configuration files and Write-Ahead Log (WAL) files.

Pros of pg_basebackup

• Suitable for large-scale databases
• Creates a complete backup of the entire database cluster
• Supports Point-In-Time Recovery (PITR)

Cons of pg_basebackup

• Cannot selectively back up specific database objects
• Requires more storage space compared to logical backups

3. Third-Party PostgreSQL Backup Tools

In addition to built-in tools, there are numerous third-party backup solutions available for PostgreSQL. In this section, we'll discuss five of the most popular options: Barman, WAL-E, WAL-G, pgBackRest, and Stolon.

3.1. Barman

Barman, or Backup and Recovery Manager, is an open-source solution for managing PostgreSQL backups. It provides a centralized backup solution for your PostgreSQL instances and supports both physical and logical backups.

Pros of Barman

• Centralized backup management
• Supports both physical and logical backups
• Can selectively back up specific database objects
• Allows remote recovery via a thin backup

Cons of Barman

• Requires additional setup and configuration compared to built-in tools

3.2. WAL-E

WAL-E is an open-source tool that performs continuous archiving of PostgreSQL via Write-Ahead Logs (WAL). WAL-E focuses on archiving, compression, and encryption, which makes backups more storage-efficient and secure.

Pros of WAL-E

• Efficient storage and encryption
• Supports various storage backends, such as Amazon S3, Google Cloud Storage, or local filesystem
• Compatible with other PostgreSQL utilities like pg_basebackup

Cons of WAL-E

• Additional setup and configuration required
• Primarily designed for archiving, rather than complete backup management

3.3. WAL-G

WAL-G is a successor to WAL-E, focused on better performance and storage efficiency. It maintains the same core concepts but introduces improvements in speed, reliability, and storage algorithms for PostgreSQL backups.

Pros of WAL-G

• Improved performance compared to WAL-E
• Efficient storage and encryption
• Compatibility with various storage backends
• Incremental backups

Cons of WAL-G

• Additional setup and configuration required

3.4. pgBackRest

pgBackRest is an open-source backup solution designed specifically for PostgreSQL. It focuses on high-performance backups and restore processes, providing advanced features like parallel and incremental backups.

Pros of pgBackRest

• High-performance backup and restore processes
• Parallel and incremental backups
• Supports local, remote, and cloud storage

Cons of pgBackRest

• Configuration can be complex for inexperienced users

3.5. Stolon

Stolon is an open-source PostgreSQL high availability and failover tool that also provides backup management capabilities. It's a full-featured solution for managing PostgreSQL instances in a cloud-native environment.

Pros of Stolon

• High availability and failover capabilities
• Integration with tools like pg_basebackup and pg_rewind
• Simplifies backup and recovery in cloud-native environments

Cons of Stolon

• Designed primarily for high availability management, not solely for backups

4. Automated PostgreSQL Backup Solution: Slik Protect
