+
+# Back Up and Restore TiDB Serverless Data
+
+This document describes how to back up and restore your TiDB Serverless cluster data on TiDB Cloud.
+
+> **Tip:**
+>
+> To learn how to back up and restore TiDB Dedicated cluster data, see [Back Up and Restore TiDB Dedicated Data](/tidb-cloud/backup-and-restore.md).
+
+## Limitations
+
+- It is important to note that TiDB Serverless clusters only support in-place restoring from backups. When a restore is performed, tables in the `mysql` schema are also impacted. Hence, any changes made to user credentials and permissions or system variables will be rolled back to the state when the backup was taken.
+- Manual backup is not yet supported.
+- PITR (Point-in-time Recovery) is not yet supported.
+- The cluster will be unavailable during the restore process, and existing connections will be terminated. You can establish new connections once the restore is complete.
+- If any TiFlash replica is enabled, the replica will be unavailable for a while after the restore because data needs to be rebuilt in TiFlash.
+
+## Backup
+
+Automatic backups are scheduled for your TiDB Serverless clusters according to the backup setting, which can reduce your loss in extreme disaster situations.
+
+### Automatic backup
+
+By the automatic backup, you can back up the TiDB Serverless cluster data every day at the backup time you have set. To set the backup time, perform the following steps:
+
+1. Navigate to the **Backup** page of a TiDB Serverless cluster.
+
+2. Click **Backup Settings**. This will open the **Backup Settings** window, where you can configure the automatic backup settings according to your requirements.
+
+    - In **Backup Time**, schedule a start time for the daily cluster backup.
+
+        If you do not specify a preferred backup time, TiDB Cloud assigns a default backup time, which is 2:00 AM in the time zone of the region where the cluster is located.
+
+    - In **Backup Retention**, configure the minimum backup data retention period.
+
+        The backup retention period must be set within a range of 7 to 90 days.
+
+3. Click **Confirm**.
+
+### Delete backup files
+
+To delete an existing backup file, perform the following steps:
+
+1. Navigate to the **Backup** tab of a cluster.
+
+2. Click **Delete** for the backup file that you want to delete.
+
+## Restore
+
+TiDB Serverless only supports in-place restoration. To restore your TiDB Serverless cluster from a backup, follow these steps:
+
+1. Navigate to the **Backup** page of a cluster.
+
+2. Click **Restore**. This will open the **Restore** window.
+
+    1. Choose a backup from the **Backup Time** drop-down list.
+    2. Click **Confirm** to begin the restoration process.
+
+   After initiating the restore process, the cluster status changes to **Restoring**. The cluster will be unavailable during the restore process and existing connections will be terminated. Once the restore process completes successfully, you can access the cluster as usual.
