 ## Automatic backups
 
-TiDB Cloud automatically backs up your instance data, letting you restore data from a backup snapshot to minimize data loss in the event of a disaster.
+{{{ .premium }}} offers enhanced automatic backup capabilities, combining high-frequency snapshots with log backups to maximize data reliability for production environments.
 
-### Learn about the backup setting
+### Automatic backup policies
 
-Compared with {{{ .starter }}} clusters and {{{ .essential }}} clusters, {{{ .premium }}} offers enhanced backup capabilities, including longer retention and hourly backup support.
+{{{ .premium }}} instances provide a comprehensive data protection strategy through a multi-layered backup architecture:
 
-| Backup setting   | {{{ .starter }}} (free) | {{{ .starter }}} (with spending limit > 0) | {{{ .essential }}} | {{{ .premium }}} |
-|------------------|--------------------------|---------------------------------------------|--------------------|------------------|
-| Backup Cycle     | Daily                    | Daily                                       | Daily              | Daily + Hourly   |
-| Backup Retention | 1 day                    | 30 days                                     | 30 days            | Up to 33 days    |

+- Point-in-Time Recovery (PITR)
+    - Retention period: 7 days.
+    - Restore granularity: supports restoration to any specific moment within the 7-day retention window.
 
-- **Backup Cycle** determines how frequently backups are created.
+- Hourly backup snapshot
+    - Retention period: 7 days.
+    - Restore granularity: supports restoration to any specific hourly snapshot generated within the 7-day retention window
 
-    - Premium instances support both **daily** and **hourly** backups.
-    - The **default** is **hourly backups**.
+- Daily backup snapshot
+    - Retention period: 33 days.
+    - Restore granularity: supports restoration to any daily snapshot (captured at 0:00 UTC by default) within the 33-day retention window.
 
-- **Backup Retention** is the duration for which backups are retained. Expired backups cannot be restored.
+### Backup execution rules
 
-    - Premium instances can retain backups for up to **33 days**.
+- Backup cycle: {{{ .premium }}} instances support both daily and hourly automatic backups.
 
-- **Backup Time** is the scheduled start time for backups.
+- Backup schedule:
+    - Hourly backup: always runs at the start of every hour (on the hour).
+    - Daily backup: executed daily at 0:00 UTC.
+    - Currently, backup time management or customization is not supported.
 
-    - For Premium instances, **daily backups** can be configured to start at a preferred time (in 30-minute intervals), while **hourly backups** always run on the hour.
+- **Retention mechanism**: backups that exceed their retention period (7 days or 33 days) automatically expire and cannot be restored.
 
-### Configure the backup settings
-
-To configure backups for a {{{ .premium }}} instance, perform the following steps:
-
-1. Navigate to the [**Backup**](#view-the-backup-page) page of your TiDB instance.

-        - You can configure **Backup Retention** (1–33 days).
-    - **Daily Backup**:
-        - Runs at a configurable time in **30-minute intervals**.
-        - You can configure both **Backup Retention** (1–33 days) and **Backup Time**.
-
-4. Click **Save** to save your settings.
+> **Note:**
+>
+> - Storage costs for automatic backups are calculated based on your backup data volume and retention duration.
+> - To extend a backup retention period beyond the default limits, contact [TiDB Cloud Support](https://docs.pingcap.com/tidbcloud/tidb-cloud-support).
