Postgresus delivers a streamlined experience that allows teams to focus on their core work rather than backup tool management.

Backup Strategies

Both tools support different approaches to PostgreSQL backup, but they handle implementation differently. Understanding these strategies helps you plan your disaster recovery procedures effectively.

Physical Backups

Postgresus supports full physical backups with compression and encryption enabled by default. The web interface lets you trigger backups manually or configure automated schedules. Restoration is straightforward — select a backup and click restore.

WAL-G creates base backups using pg_start_backup and pg_stop_backup commands internally. You execute backups through CLI commands and must track backup history manually. Restoration requires multiple command executions and careful attention to recovery configuration.

Continuous Archiving

Both tools support WAL archiving for point-in-time recovery:

• Postgresus handles WAL management automatically with built-in retention policies
• WAL-G requires manual archive_command configuration in PostgreSQL
• Postgresus provides visual timeline selection for PITR
• WAL-G restoration requires specifying exact recovery targets via configuration

Storage Options

Modern backup strategies require flexibility in where backups are stored. Both tools support multiple cloud and local storage destinations.

Supported Storage Backends

Postgresus and WAL-G both support popular cloud storage services:

• Amazon S3 and S3-compatible storage
• Google Cloud Storage
• Microsoft Azure Blob Storage
• Local filesystem and NAS devices

Postgresus additionally supports SFTP and integrates with Google Drive, providing more options for diverse infrastructure requirements. The web interface makes configuring multiple storage destinations simple, while WAL-G requires separate configuration for each backend.

Performance and Efficiency

Backup performance impacts production database operations. Both tools implement optimizations to minimize overhead during backup operations.

Compression

Postgresus offers multiple compression algorithms optimized for different scenarios. The intelligent defaults work well for most users while advanced options remain available for fine-tuning. WAL-G supports LZ4, LZMA, Brotli and ZSTD compression with configurable levels.

Parallelization

Both tools support parallel upload and download operations. Postgresus configures parallelization automatically based on available resources. WAL-G requires manual tuning of concurrency settings through environment variables.

Monitoring and Notifications

Proactive monitoring ensures backup failures are caught before they become disasters. The ability to receive alerts when something goes wrong is crucial for maintaining data protection.

Postgresus Monitoring

Postgresus includes a comprehensive monitoring system:

• Real-time backup status dashboard
• Email, Slack, Discord, Telegram and Microsoft Teams notifications
• Webhook integrations for custom alerting
• Backup health checks with automatic alerts
