Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the documentation for TiDB Cloud premium instances by detailing the newly supported manual backup feature. It provides users with essential information on how to create and manage manual backups, their characteristics, and how they integrate with existing restore options. Additionally, it clarifies the updated Point-in-Time Recovery window for premium instances, ensuring the documentation accurately reflects current service capabilities.

Highlights

  • Manual Backup Support: Introduced comprehensive documentation for manual backup functionality for premium instances, including key characteristics, retention policies, storage, cost implications, limitations, and step-by-step creation instructions.
  • PITR Window Adjustment: Updated the Point-in-Time Recovery (PITR) window for premium instances from 33 days to 7 days, clarifying that PITR is not supported for manual backups.
  • Naming Consistency: Ensured consistent use of the {{{ .premium }}} variable throughout the document for accurate branding.
  • Removed Manual Backup Limitation: Eliminated the previous note stating that manual backups were not supported, reflecting the new feature availability.

Code Review

This pull request effectively documents the new manual backup feature for premium instances, updates the Point-in-Time Recovery (PITR) window, and improves naming consistency. The changes are well-structured and clear. I have provided a few minor suggestions to enhance grammar, voice, and formatting consistency, aligning with the documentation style guide.

# Back Up and Restore {{{ .premium }}} Data

This document describes how to back up and restore your data on {{{ .premium }}} instances. {{{ .premium }}} supports automatic backup and lets you restore backup data to a new instance as needed.

The last sentence uses passive voice ("It can be restored"). The style guide recommends using active voice and addressing the user directly with "you" to improve clarity.

- **Point-in-Time Restore**: restores your instance to a specific point in time.

- Premium instances: can be restored to any time within the last 33 days, but not earlier than the instance creation time or later than one minute before the current time.
- Premium instances: can be restored to any time within the last 7 days, but not earlier than the instance creation time or later than one minute before the current time. (Note: PITR is not supported for manual backups)

The (Note: ...) format is inconsistent with the style used for notes elsewhere in the documentation. To improve consistency, it's better to integrate the note into the sentence or use the standard blockquote format for notes.
