September 2025 monthly summary for percona/percona-backup-mongodb focusing on delivering storage reliability, feature readiness for large object support, and safer defaults. The month included key feature work to complete the storage interface, introduction of a middleware for large object handling, and configuration improvements, alongside critical core fixes to improve data safety and clarity.

In 2025-08, delivered a focused set of OSS storage enhancements and code-quality improvements for percona/percona-backup-mongodb, aimed at reliability, security, and maintainability of object storage workflows. The work emphasizes correctness of OSS storage configuration, robust multipart upload handling, stronger encryption options, and cleaner, more maintainable code. Key features delivered: - OSS storage configuration correctness and security hardening: fixed missing cast for OSS config, added credential masking, added clone capability for OSS client config, and tightened connect timeout handling (default 5s) to improve reliability and security of OSS storage setup. - OSS multipart uploads and part size config: implemented multipart upload and copy for OSS, using oss.NewUploader and oss.NewCopier, added configurable part size, and simplified behavior by removing LeavePartsOnError; includes unit tests for ComputePartSize. - Server-side encryption for object storage: added support for AES256, KMS, and SM4 encryption methods, applying encryption settings to uploads and copies and aligning with multipart size config. - Code cleanup and minor fixes: removed unused path.Join in Delete method and corrected/clarified Copy method comments. Overall impact: - Increased reliability and security of OSS-backed backups, reducing operational risk and rollback costs. - Improved performance and scalability through multipart uploads and configurable part sizing. - Strengthened security posture with integrated server-side encryption options. - Improved code quality, test coverage, and maintainability, enabling faster future iterations.
