Open-source tool Restoredrill launches to automate PostgreSQL backup verification
The utility tests database restores in temporary containers and generates structured evidence reports for compliance audits.
The short version
- An open-source tool called Restoredrill (v0.1.0) has been released to automate the process of testing PostgreSQL backups.
- The tool restores backups into a temporary Docker container to run prechecks, structural checks, read-path queries, and recovery metrics.
- It outputs timestamped JSON reports specifically structured to serve as evidence for regulatory and compliance frameworks like SOC 2, ISO 27001, and AWS FTR.
Key facts
- Restoredrill v0.1.0 is an open-source utility built exclusively for verifying PostgreSQL backups.[Hacker News]
- The tool validates backups by deploying them to an ephemeral container on local systems or CI runners, which makes it unsuitable for multi-terabyte databases that require dedicated infrastructure.[Hacker News]
- The validation process runs in tiers, including prechecks for RPO freshness, structural checks like sequence integrity, read-path SQL queries, and RTO tracking.[Hacker News]
- It supports both local file systems and Amazon S3 as backup sources, and integrates with monitoring systems like Prometheus and Slack.[Hacker News]
- Every check in the tool is designed to fail-closed, meaning any configuration or execution failure is reported as a full drill failure rather than a skip.[Hacker News]
What remains uncertain
- Because Restoredrill is in its early stages (v0.1.0), core features and configurations may change in future iterations.[Hacker News]
