Summary by CodeRabbit

• Documentation
  • Updated backup and restore concepts with BYOC-specific wording, broader scope beyond Dedicated, and revised “for more information” links.
  • Added a new Restore subsection under Point-in-time Restore, clarifying restore sources and that PITR applies only to automatic backups (not manual backups), with restores creating new instances.
  • Updated Premium backup/restore guidance to include BYOC, including CustomContent coverage, plan-specific recycle bin restore steps, and cloud-storage restore instructions.
  • Refined BYOC AWS setup and service initialization references to use consistent “TiDB Cloud console” wording.

Code Review

This pull request updates the TiDB Cloud backup and restore documentation to incorporate the BYOC (Bring Your Own Cloud) plan type, detailing its backup and restore capabilities. The review feedback highlights minor spacing and formatting inconsistencies around template variables like {{{ .premium }}} and {{{ .byoc }}} that should be corrected for consistency.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Scope the complete restore procedures for BYOC, not only the introduction and labels.

The new text states that this document applies to BYOC, but the shared procedure still contains Premium-only wording and links: Restore to a new Premium instance, “Premium instances” for PITR, the deleted Premium instance description, and the cloud-storage step linking to Create a Premium Instance. BYOC readers can therefore follow the wrong plan’s instructions. Wrap the full applicable procedures in plan-specific blocks or replace these references with genuinely plan-neutral guidance and BYOC targets.
