Barman - PostgreSQL Backup and Disaster Recovery

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

## Overview Barman (Backup and Recovery Manager) is an open source disaster-recovery tool for PostgreSQL. This AMI delivers a fully configured Barman appliance protecting a bundled, security-hardened PostgreSQL 16 source out of the box - eliminating hours of manual streaming-replication, WAL-archiving, and retention-policy setup. It ships Barman with PostgreSQL 16 from the official PGDG repository. ## Deploy in Minutes, Not Hours Launch the instance, connect over SSH, and run `barman check pg` to confirm the backup source is healthy. Run `barman list-backup pg` to see the base backup taken automatically on first boot. Run `barman recover pg latest` to restore to a directory. The entire workflow is proven before you touch a configuration file - no manual streaming or archiving setup required. ## Why This Image Over Alternatives Unlike community setups that pile the backup catalogue onto the OS disk or ship a well-known database password, this image: - Places the entire Barman catalogue - every base backup and streamed WAL segment - on a dedicated, independently resizable EBS volume

• Rotates unique per-instance database passwords on first boot
• Binds the demo PostgreSQL source to loopback only with scram-sha-256 authentication
• Configures a named replication slot so WAL is never lost ## What Is Included - Barman from the official PGDG package repository
• PostgreSQL 16 as a bundled, loopback-only demo backup source
• Streaming backup method - Barman drives pg_basebackup and pg_receivewal over a replication connection with a named replication slot
• Continuous WAL archiving and point-in-time recovery configured and verified on first boot
• Dedicated EBS catalogue volume for all backups and WAL segments
• Scheduled backups - WAL streaming health check every minute and a daily base backup running automatically ## Secure First Boot On first boot a one-shot service generates cryptographically strong passwords for the PostgreSQL, Barman, and replication roles - unique to that instance. Passwords are written only to the Barman user's protected password file. The first base backup is taken and verified before the boot sequence completes. No shared or default database credential ever exists in the image. ## Backing Up Your Own PostgreSQL Servers The bundled PostgreSQL source is a working demonstration. To protect production databases, add a Barman server configuration pointing at your PostgreSQL host and grant Barman a replication connection. The multi-server setup guide walks through network reachability, security group considerations, and retention policy design. To discuss your architecture or request a free sizing consultation, contact our team through the support channels provided. ## AWS Integration Points - Amazon EBS - The backup catalogue lives on a dedicated EBS volume; use EBS Snapshots for off-instance copies or resize storage independently of the OS disk.
• Amazon VPC - Deploy within private subnets and reach your PostgreSQL servers over private networking; the demo database never listens on a public interface.
• Amazon CloudWatch - Forward Barman and PostgreSQL logs and system metrics to CloudWatch for centralized backup monitoring and alerting.
• AWS Backup - Schedule automated, policy-driven snapshots of the catalogue volume without custom scripting. ## Use Cases - PostgreSQL disaster recovery - Maintain base backups and continuous WAL archiving so any production PostgreSQL server can be restored to a precise point in time after data loss or corruption.
• Centralized backup for a database fleet - Run one Barman host that manages backups and retention policies for many PostgreSQL servers from a single operational surface.
• Compliance and retention - Enforce redundancy and recovery-window retention policies with scheduled, verifiable backups on a dedicated, snapshottable volume. ## Evaluation Path Launch the AMI on a small instance type to evaluate the full backup and recovery workflow before scaling to production. The image is fully functional immediately - inspect backup output, test point-in-time recovery, and validate integration with your existing PostgreSQL servers at minimal infrastructure cost. ## 24/7 cloudimg Support cloudimg engineers provide round-the-clock technical support by email and live chat.
