7.3 Backing up data in JP1/AO (Linux cluster configuration)
This section describes how to back up configuration information and database information for JP1/AO before performing tasks such as migrating JP1/AO to a new host or maintaining the database.
- Important
When you back up and restore data in a JP1/AO system, some elements of the data do not survive the backup process. For example, some detailed task information (step lists and progress information) is lost, and some task statuses are changed.
Make sure that sufficient free space is available on the disk on which the folder for backup files is located. As a general rule, the amount of free space should exceed the size of the backup files by 20 MB.
Who can perform this task:
Users who have root permission for the OS and cluster management permission
To back up a JP1/AO system (cluster configuration):
-
Make sure that there are no tasks in execution status (In Progress, Waiting for Input, In Progress (with Error), In Progress (Terminating), or Long Running). If there are such tasks in the system, either stop the tasks, or wait until they enter Completed or Failed status.
In the cluster software, take the resource group in which JP1/AO is registered offline.
Disable starting, stopping, and monitoring of the following resources in the cluster software. For details on how to do so, see the documentation for the cluster software.
Common component database
HBase 64 Storage Mgmt SSO Service
HBase 64 Storage Mgmt Web SSO Service
HBase 64 Storage Mgmt Web Service
HAutomation Engine Web Service
In the cluster software, place online the resource group in which JP1/AO is registered.
Execute the backupsystem command to back up the JP1/AO database and configuration information.
- Tip
The backupsystem command does not back up the files below. Back them up manually as needed.
SSL server certificate files for https connections
Private key files for https connections
Private key files for public key authentication
Cluster service control commands created by users
In the cluster software, take the resource group in which JP1/AO is registered offline.

HBase 64 Storage Mgmt Web SSO Service
HBase 64 Storage Mgmt Web Service

Result of operation:
Data is backed up to the specified backup folder.
