Backing up, archiving, and restoring applications
Use the applications catalog to back up, archive, and restore applications.
Application status that is monitored and detected by policies will help you
determine the maintenance action that you need to perform. By default, the
application property Application Backup for Archiving and Restore is
not available for selection in this release of the product because some business
components of composite applications do not support backup, archive, and restore.
You can make application backup available by editing the backup.properties file.
To make Application Backup for Archiving and Restore available
for use in your portal environment, edit the backup.properties file:
- On the IBM® WebSphere® Portal Express server, open
a command prompt.
- Locate wp_profile_root/shared/app/ai.xml.impl.service.jar and
open the backup.properties file for editing.
- To turn on backup for all composite applications, specify all.backup.block=false.
CAUTION:If you make application backup available in your
production environment, heed the Warning that displays for business components
that do not support backup, archive, and restore. If you back up applications
containing business components that do not support full-cycle backup, archive,
and restore, you will lose application information or entire business components.
For example, Document Libraries that are deployed as Document Manager business
components within composite applications cannot be restored if you back them
up because they are deleted during archiving.
If you are an administrator or an application manager, you can perform
advanced actions from within the applications catalog:
- Backing up applications
- Archiving applications
- Restoring applications
- Deleting applications
- Unlocking applications
If an application has exceeded the limits set
by its policy for size, inactivity, and lack of modification, the application
is locked. The padlock icon is displayed in front of the application name
in the catalog. If you are an administrator or an application manager, you
can click the padlock icon to unlock the application. Then open the application
to refine the elements that require attention.
Note: The Backup and Archive actions are available if , when you edit the
application properties, you set the property Application Backup
for Archiving and Restore to Enable backup.
The Restore action is available if you have backed up or archived applications.
If the application property Application Backup for Archiving and
Restore is not available for selection, edit the default backup.properties to
turn on backup, archive, and restore for all composite applications.
Backing up applications
Backing
up an application locks the application and makes a copy of the application
in the default backup directory or to another directory specified in the custom
property of the WebSphere Application Server service:
- The default directory is wp_profile_root/backup.
- In the IBM WebSphere Application Server service WPApplicationInfrastructureXMLService,
the custom property is backup.root.
While an application is being backed up, it is locked for Archive,
Restore, and Delete actions.
Archiving applications
Archiving
an application locks the application, backs up the application, and deletes
it from the server. While an application is being archived, it is locked for
Backup, Restore, and Delete actions.Attention: Do not be confused
by the misleading confirmation message that states that the application is
being backed up. After you click the Archive icon,
the archive process begins: the application is locked, backed up, and deleted.
After
you archive applications, you can filter the applications catalog to show
only Archived Applications. When you work with Archived
Applications in the catalog, you can perform the following actions:
- Changing the view of the catalog
- Finding archived applications
- Viewing the Name, Owner, Archive Date, and Template of each archived application
- Restoring an archived application
The following actions are not available when the catalog displays
only Archived Applications:
- Create new applications
- Add and remove archived applications from your Favorites list
- View your favorite archived applications
- View general application status based on policy
- Display detailed status based on policy
- Back up an archived application.
Restoring applications
The
Restore action is available if you have backed up or archived an application.
Restoring an application lets you choose a backup copy or an archive copy
of the application to reinstate. While an application is being restored, the
application is locked for Backup, Archive, and Delete. When you restore a
backed-up application, you choose an older version of an existing application.
When you restore an archived application, you recreate from a backup copy
an application that has been deleted from the server. Restriction: Only
administrators can restore an archived application. This prevents application
managers from restoring an application that was archived because it exceeded
the limits on application size, inactivity, and lack of modification set by
the policy in force for the application. When an archived application is restored,
the most recent backup copy is used.
