Back up now

This topic describes how to back up a cluster or a tenant immediately.

Prerequisites

• Tenant backup is supported only in OceanBase V3.2.2-20220304134610 and later.

• A cluster in logical backup mode supports only full backup. A cluster in physical backup mode supports both full backup and incremental backup.

Procedure

You can immediately back up a cluster or tenant. The following takes cluster backup as an example.

1. In the left-side navigation pane, choose Backup & Recovery > Backup . Then, click Back up Now in the upper-right corner of the page and choose Back Up Cluster from the drop-down list.

2. Select the objects that you want to back up.

   Select the objects from the Backup Cluster drop-down list. The system automatically identifies Data and Backup Method of the cluster and automatically populates the fields of Storage Configuration .

   If Backup Mode of the cluster is logical backup, you must first install the backup service. For more information, see Install a service.

3. Specify Storage Configuration.

   • If the cluster that you want to back up has a backup strategy, the fields in the Storage Configuration section are automatically populated.

   • Otherwise, you must manually specify the values. You can specify the values as prompted or by following the instructions of step 4 in Create a backup strategy.

     After you specify the values, click Test .

   

4. Select a data backup mode.

   For physical backup, select a data backup mode. For logical backup, only full backup is supported. Notice

   For physical backup, you must perform a full backup before you can perform an incremental backup. Otherwise, the following error message is returned in the Check if ready to data backup step: Full data backup needed before incremental data backup.

   If the error message "Cluster compaction needed before full data backup" is returned in the Start cluster compact if necessary step of a full backup, Perform a major compaction and click Retry .

5. Click Back up Now .
