Arun updated the TigerGraph/server-docs repository to clarify Backup High Availability (HA) behavior, focusing on how backup processes operate during GPE or GSE downtime and the limitations posed by full node failures. He revised the index.adoc documentation using AsciiDoc, ensuring users understand the continuity and risks associated with backup operations during outages. Arun’s work aligned the documentation with TigerGraph’s reliability roadmap, explicitly noting that full node failure tolerance is planned for a future release. His contribution demonstrated strong documentation skills and attention to technical accuracy, providing clear guidance for users and laying groundwork for future enhancements in HA support.
