pgBackRest

What pgBackRest is

pgBackRest is a free, open-source backup and restore solution for PostgreSQL, designed for large databases and workloads. It supports full, differential and incremental backups at file or block level, with parallel processing and compression options such as lz4 and zstd. A custom protocol handles local or remote backup, restore and archiving through TLS or SSH. Repositories can use S3-, Azure- and GCS-compatible object storage, and the repository can be encrypted wherever stored. pgBackRest calculates checksums for backup files and checks them again during restore or verification. With versioned object storage, users can view a repository as it existed at a point in time; S3 object locking and Azure or GCS soft delete are also described as tampering protections. The project supports ten PostgreSQL versions, including the five currently supported versions and the last five end-of-life versions. It runs on Linux as self-hosted software, with installation guides for Debian, Ubuntu and RHEL. Bug reports can be submitted, and sponsors offer products and services that include pgBackRest support. The plan is free under the MIT license for personal or commercial use.
