Lotus Quickr for WebSphere Portal allows you to back up, archive, and restore places just as you back up, archive, and restore composite applications in IBM WebSphere Portal.
As with any production-critical programs, you should plan for backup and recovery in the event of a system crash. Because Lotus® Quickr™ stores its data in DB2® by default, you should familiarize yourself with the backup and recovery capabilities provided with DB2. For more information, refer to the DB2 information center
Quickr places are an extension of the composite application infrastructure. Therefore, you should be familiar with the concepts and tasks related to composite applications in WebSphere Portal as a prerequisite to working with Lotus Quickr places.
Backup, archive, and restore of a Quickr place allows portal administrators and application managers to make a backup copy of a place, archive the place, and, when needed, restore the archived place. Place status that is monitored and detected by policies will help you determine the maintenance action that you need to perform.
Backing up an application temporarily locks the application and makes a copy of the application. The copy is created in the default backup directory or another directory specified in the custom property of the WebSphere Portal Server service:
- The default directory is quickr_server_root/wp_profile/PortalServer/backup
- The Resource Environment Provider is WP_AIInitService
- The custom property is named backup.root
- This location must be a shared directory for all nodes in the cluster (for more information, refer to this article)
When you create backup or an archive a new folder is created for an individual place. When you backup a place, a copy of the place is created on your system leaving the place accessible from the places catalog. When you archive a place, a copy of the place is created on your system and the place is removed from the places catalog. Backups and archives use the same file type to store a place and both are stored in the backup directory on the Lotus Quickr server. The default location is quickr_server_root
You need to plan where the backups are going to be kept, if you have limited room on your Lotus Quickr server, you may want to store your backups in separate location. The new backup file does not overwrite the old backup. If you create 5 backups of a 5GB place, you will use 25GB of storage space. Regular backup maintenance should be performed to clear out old backup versions. Backup maintenance can be done manually or it can be scripted. After a Backup or archive file is deleted from the file system, you will need to run an xmlaccess script to remove the place from the Places Catalog.
