## What it is
pgBackRest is a reliable backup and restore tool for PostgreSQL that scales to the largest databases and workloads. It supports parallel full, differential, and incremental (file or block level) backups, WAL archiving, and local or remote repositories on disk or object storage like S3, Azure, and GCS.

## Use cases
- back up a large PostgreSQL database in parallel with compression
- set up WAL archiving and point-in-time recovery for Postgres
- store PostgreSQL backups in S3, Azure Blob, or GCS
- run incremental or differential backups of a Postgres cluster
- restore a terabyte-scale PostgreSQL database quickly
- maintain multiple backup repositories with different retention policies
- verify backup integrity with checksums

## When to choose
- you need reliable, scalable PostgreSQL backup and restore with WAL archiving
- your databases are large and backup speed matters (parallelism, lz4/zstd)
- you want backups on cloud object storage or remote repositories over TLS/SSH
- you need block-level incremental backups or point-in-time recovery

## When to avoid
- you back up databases other than PostgreSQL
- you want a simple GUI-managed backup solution
- you need a lightweight dump-only workflow where pg_dump suffices
