Accelerating Postgres Backups: A Comprehensive Guide to Swift and Efficient Backups


Ensuring data security through backups is crucial for any business with a Postgres database. However, taking frequent backups can be tedious and time-consuming, which is why optimizing the process is essential. In this comprehensive guide, we will discuss a variety of techniques to help you optimize your Postgres backups for speed, including parallelism, utilizing delta backups, and file compression. By following these best practices, you can create faster, more efficient backups without compromising data integrity, allowing your business to run smoothly and effectively. Additionally, we will introduce a simple to use solution from Slik Protect that automates PostgreSQL Backups and restorations at a regular interval once configured. The user can set it up in less than 2 minutes, and once configured, the user can be confident that their data would be secured and never compromise on business continuity.

A well-optimized Postgres backup strategy is essential for businesses that rely on their databases. With an optimized process, you can ensure faster backups while minimizing the impact on your production environment. This guide will explore various techniques for optimizing your Postgres backups, helping you make informed decisions when designing your backup strategy.


One of the most effective methods for speeding up your Postgres backups is by using parallelism. Parallelism allows your backup process to perform multiple tasks simultaneously, leveraging the full potential of your hardware resources.

To implement this technique, you can use various tools like pgBackRest and pg_dump. In pgBackRest, you can use the --process-max option to specify the maximum number of threads to use for the backup. For pg_dump, you can use the --jobs option to run multiple jobs in parallel, boosting your backup speed significantly.

Remember that using parallelism requires sufficient disk I/O, CPU, and memory resources. Monitoring your system resources can help you find the sweet spot between performance and resource usage.

Delta Backups

Delta backups, also known as incremental backups, store only the changes that occurred since the last backup. This technique can notably reduce backup time and storage space while maintaining data integrity.

To create delta backups, you can utilize tools like pgBackRest. This tool supports both full and delta backups, allowing you to mix and match these techniques for an efficient backup strategy. By configuring the --type option in pgBackRest, you can choose between full (full), differential (diff), or incremental (incr) backups.

The key difference between differential and incremental backups lies in their reference points. Differential backups store data changes since the last full backup, while incremental backups record changes since the prior differential or incremental backup.

Remember to periodically perform full backups, followed by a sequence of delta backups. This approach ensures swift restoration while maintaining data consistency.

File Compression

Compressing backup files can significantly reduce storage space and speed up data transfers. Most backup tools include built-in compression options, simplifying the process.

In pg_dump, you can use the --format option with --file to create a custom format dump, which is already compressed. To control the compression level, use the --compress flag.

Similarly, pgBackRest provides a --compress-level option. This setting allows you to fine-tune the balance between compression speed and space savings.

Keep in mind that compression requires additional CPU resources. Testing various compression levels can help optimize performance while reducing storage consumption.

Other Optimization Techniques

Some additional methods for optimizing Postgres backups include:

  • Batching transactions: By wrapping multiple database actions into a single transaction, you can reduce the time necessary for individual transaction log flushes.
  • Table partitioning: Partitioning large tables into smaller, manageable subsets can simplify the backup process and improve performance.
  • Optimizing hardware resources: Ensure that your backup server has adequate CPU, memory, and disk resources. This may involve upgrading your current infrastructure or configuring your system for optimal performance.
  • Offsite backups: Backup solutions that support offsite storage, such as Amazon S3 or Azure Blob Storage, can ensure business continuity and disaster recovery.
