pghoard VS LayerStack Arm-based Cloud Server

• Multi-cloud object storage support
  pghoard supports backing up to multiple cloud storage providers including AWS S3, Google Cloud Storage, Azure Blob Storage, Swift, and local filesystem, giving flexibility in choosing or switching backup destinations.
• Streaming WAL archiving and compression
  It supports continuous WAL streaming and archiving with built-in compression (using algorithms like Snappy, LZMA, or zstd) and encryption, reducing storage costs and improving backup transfer efficiency.
• Point-in-time recovery (PITR)
  pghoard enables point-in-time recovery by combining base backups with WAL segments, allowing restoration of a PostgreSQL database to any specific moment, which is critical for disaster recovery scenarios.
• Open source and actively maintained by Aiven
  Being maintained by Aiven, a company specializing in managed database services, pghoard benefits from real-world production use, ongoing updates, and community contributions, ensuring reliability and continued support.
• REST API and monitoring integration
  It provides a REST API for managing and monitoring backup operations, and can integrate with monitoring systems, making it easier to automate backup workflows and track backup health in production environments.

Possible disadvantages

• PostgreSQL-specific tool
  pghoard is designed exclusively for PostgreSQL, so organizations using multiple database systems would need separate backup solutions for other databases, increasing operational complexity.
• Complex initial setup and configuration
  Setting up pghoard requires careful configuration of cloud storage credentials, encryption keys, and WAL-G-like settings, which can be complex for users unfamiliar with PostgreSQL internals or cloud storage APIs.
• Limited GUI or dashboard
  pghoard primarily operates via command-line and configuration files with a basic REST API, lacking a polished web-based dashboard for easier visualization and management compared to some commercial backup solutions.
• Documentation gaps for edge cases
  While basic documentation exists, users have reported that some advanced use cases, troubleshooting steps, and edge-case scenarios are not thoroughly documented, requiring deeper investigation into the source code.
• Smaller community compared to alternatives
  Compared to more widely adopted tools like pgBackRest or Barman, pghoard has a smaller user community and fewer third-party resources, tutorials, or plugins, which may limit support options for troubleshooting.

• Cost-Effective Performance
  Arm-based servers from LayerStack typically offer a lower price point compared to traditional x86 instances while delivering competitive performance for many workloads, making them attractive for budget-conscious users.
• Energy Efficiency
  ARM architecture is known for its power efficiency, which can translate into lower operational costs and a smaller environmental footprint for running cloud workloads.
• Good for Scalable Workloads
  These servers are well suited for horizontally scalable applications like web servers, microservices, and containerized workloads that can take advantage of multiple ARM cores efficiently.
• Simple Deployment
  LayerStack provides an easy-to-use control panel and API for deploying ARM-based cloud servers quickly, reducing the setup time for developers and businesses.
• Global Data Center Availability
  LayerStack offers multiple data center locations, allowing users to deploy ARM-based servers closer to their target audience for reduced latency.

Possible disadvantages

• Limited Software Compatibility
  Not all software and applications are optimized or even compatible with ARM architecture, which can create challenges for users relying on x86-specific dependencies or legacy systems.
• Smaller Ecosystem Support
  Compared to established x86 cloud offerings, ARM-based cloud services from LayerStack may have a smaller community, fewer third-party integrations, and less extensive documentation.
• Performance Variability for Certain Workloads
  While ARM excels at parallelizable and lightweight tasks, it may underperform for heavy single-threaded applications or specialized workloads that benefit from x86 optimizations.
• Migration Complexity
  Switching from x86-based infrastructure to ARM-based servers may require significant re-testing, recompilation, or code changes, adding overhead for businesses transitioning existing systems.
• Fewer Managed Service Options
  LayerStack's ARM offerings may have fewer managed services, pre-configured images, or specialized ARM-optimized tools compared to larger providers like AWS Graviton, limiting flexibility for advanced users.

• Pgbackrest is no longer being maintained

  The "closest" would be using Barman with hook scripts (https://docs.pgbarman.org/release/3.18.0/user_guide/hook_scripts.html#hook-scripts-using-barman-cloud-scripts-as-hooks-in-barman) if you rely on cloud storage for storing backups.... - Source: Hacker News / 6 months ago

• Future PostgreSQL: improvement to the replication protocol

  This story starts with our own PgHoard, a PITR backup tool for PostgreSQL. PgHoard offers several methods to archive the WAL (Write Ahead Log), including pg_receivewal, a small application shipping with PostgreSQL which connects to a... - Source: dev.to / almost 5 years ago
