01 Physical Backup
Note: Before initiating a physical backup, please ensure that HDFS has been successfully deployed and that a backup storage target has been successfully added in XPanel under "Cluster Management" -> "Backup Storage Target Management".
Initiate a full backup by clicking on "Initiate Full Backup" in XPanel, which will immediately start the cluster physical backup task.
Verify the progress of the physical backup:
- In XPanel, click on "Cluster Backup List" -> "Physical Backup" to view the status of the initiated physical backup task.
- Verify on HDFS whether the backup was successful.
Execute the command on the HDFS machine:
hadoop fs -ls /kunlun/backup/xtrabackup/$cluster_name/
# $cluster_name refers to the cluster name, for example, cluster_1689905581_000001, which can be copied from the first step.
Example:
hadoop fs -ls /kunlun/backup/xtrabackup/cluster_1689905581_000001/
