Back up a cluster now

This topic describes how to back up a cluster immediately.

You can back up a cluster immediately by using the following methods.

• Method 1: Log in to the OceanBase Cloud Platform (OCP) console. In the left-side navigation pane, choose Backup & Recovery > Backups. On the Backups page, click Back up Now in the upper-right corner of the page and select Back Up Cluster from the drop-down list.

• Method 1: Log in to the OCP console and go to the Overview page of the target cluster. In the left-side navigation pane, click Backup & Recovery. Then, click Back up Now.

Prerequisites

• To back up a cluster by using Method 1, make sure that you have the following permissions:

  • Resource Permissions: Cluster Maintenance or Tenant Maintenance permission
  • Menu Permissions: Permission on the Backup menu of Backup & Recovery

• To back up a cluster by using Method 2, make sure that you have the following permissions:

  • Resource Permissions: Cluster Maintenance permission
  • Menu Permissions: Permission on the Backup & Recovery menu of Clusters

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

• The cluster to be backed up is not in the Upgrading state.

• OceanBase does not support backing up a tenant that is in the locked state.

Procedure

The procedure of Method 1 is described as follows:

1. Log in to the OCP console.

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

3. Select the object that you want to back up.

   Select the object that you want to back up from the Backup Cluster drop-down list. The system automatically identifies OceanBase Version and Backup Method of the cluster and populates the fields in Storage Configuration.

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

4. 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 cluster-level backup strategy.

     Then, click Test.

   

5. Select a data backup method.

   For physical backup, select a data backup method. 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.

6. Click Back up Now.
