May 2026: Delivered durable and atomic PutObject for Local and SFTP storage in wal-g. Implemented a temporary-file workflow to ensure PutObject writes complete before renaming, reducing risk of WAL data loss. Extended durability guarantees with storage-type specific handling and added networked storage compatibility checks to validate behavior across local (including NFS) and SFTP backends. This work aligns with reliability and data integrity objectives for archive operations.

March 2025: Two cross-repo feature deliveries enhancing backup efficiency and versioning reliability. Key features delivered: 1) Barman Cloud: added LZ4, XZ, and ZSTD compression support with updated configuration definitions and validation; ensured compatibility with Barman 3.12+. (commit 6848fd45696b2eb66ea2b40b4c3a006e64028bcc). 2) Timescale Docker HA: added pg_semver extension to the Docker image to enable semantic PostgreSQL versioning, improving data integrity. (commit 2cda68b9cd30622b38275c0fca0787f4b37a72c1). Major bugs fixed: none reported for these scopes. Overall impact: improved backup efficiency, reduced storage usage, and more robust versioning metadata. Technologies demonstrated: compression algorithms (LZ4, XZ, ZSTD), configuration validation, Docker image customization, PostgreSQL extensions.
