Hi @wildpcww. Thanks for your PR.

I'm waiting for a pingcap member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

This pull request introduces new documentation detailing the backup and restore functionalities available for TiDB Cloud Premium instances.

• Automatic Backup Settings: The new documentation details the automatic backup capabilities for Premium instances, including configurable backup cycles (daily and hourly), retention policies (up to 33 days), and scheduled backup times.
• Data Restoration Instructions: The page provides step-by-step guides on how to restore data using both snapshot restore and point-in-time restore methods, specifically for restoring to a new TiDB instance.
• Recycle Bin Restoration: Guidance is included on how to recover deleted instances from the Recycle Bin, detailing the process to restore backups to a new instance.
• Limitations Clarification: The documentation explicitly states that manual backups are not supported for TiDB Cloud Premium instances.
