WalkthroughThe changes made to the documentation involve rephrasing sentences to use more formal and third-person language, replacing direct references to the reader with references to users. Minor typographical errors were corrected, and some grammar modifications were applied. The technical content and the logic describing the checkpoint backup feature remain unchanged. Changes

Code Review
The pull request introduces minor changes to the documentation regarding the checkpoint backup feature in TiDB. The changes primarily focus on improving clarity and addressing the user perspective. Overall, the changes are beneficial for enhancing the user experience.
Summary of Findings
- Grammar and Typos: Several instances of grammatical errors and typos were identified, such as "recoverable errors" and "cannot affords". These should be corrected to improve the documentation's professionalism and readability.
- Consistency in Addressing Users: The documentation sometimes switches between addressing the user directly ("you can use") and referring to users in the third person ("users can use"). Maintaining a consistent second-person perspective is recommended for better engagement and clarity.
Merge Readiness
The pull request is almost ready for merging. Addressing the identified grammatical errors and ensuring consistency in addressing the user would further enhance the quality of the documentation. I am unable to approve the pull request, and recommend that others review and approve this code before merging.

9-9: Fix typo and improve clarity in interruption description
The phrase “due t recoverable errors” is missing the “o” in “to” and could be phrased more clearly.
Apply this diff for clarity and grammatical correctness:-Snapshot backup might be interrupted due t recoverable errors, such as disk exhaustion and node crash. +Snapshot backup might be interrupted due to recoverable errors, such as disk exhaustion or node crashes.
11-11: Correct the BR acronym
The acronym for Backup & Restore should remain “BR,” not “B,” to avoid confusion.-In TiDB v6.5.0, Backup & Restore (B) introduces the checkpoint backup feature to allow continuing an interrupted backup. +In TiDB v6.5.0, Backup & Restore (BR) introduces the checkpoint backup feature to allow continuing an interrupted backup.
15-15: Rephrase for grammatical accuracy and conciseness
“cannot affords” is incorrect (modal verbs require the base form), and “backup” as a verb should be “back up.” Consider tightening the sentence for readability:-If your TiDB cluster is large and cannot affords to backup again after a failure, users can use the checkpoint backup feature. +For large TiDB clusters where restarting backups is cost‑prohibitive, users can leverage the checkpoint backup feature.🧰 Tools

33-33: Remove extraneous space and refine phrasing
There’s an extra space before the period, and “if needed” can be tightened to “if necessary.”-To avoid this situation, `br` keeps the `gc-safepoint` for about one hour by default when `gcttl` is not specified.

31-31: Fix spelling typo in “periodically.”The word "perioically" is misspelled. Update it to "periodically":
During the backup, `br` periodically updates the `gc-safepoint` of the backup snapshot in PD to avoid data being garbage collected. When `br` exits, the `gc-safepoint` cannot be updated in time, so data might be garbage collected before the next retry.
