Backing up Wikis data
Back up the data in your wikis.
Before you begin
To run administrative commands, you must use the wsadmin client. For more information, see Starting the wsadmin client.
About this task
Wikis stores data in a database and on the file system. Metadata is stored in the database and binary files are stored in a data directory on the file system. You specified this directory during the installation of IBM® Connections. You can find the path to the directory in the file.storage.rootDirectory element of the wikis-config.xml file. The file.storage.rootDirectory element contains either the path itself or a WebSphere® Application Server variable whose value is the path.
This storage architecture means you must maintain consistency between the database and file system during backups. The simplest way to maintain consistency is to run offline backups by making the application inaccessible and then backing up both locations. During an online backup, users can continue to add and delete content.
You must back up the database before you back up the files on the file system because the database enforces transactional integrity. If you back up the file system first, files that are added after the file system backup starts but before the database backup completes will be missing from the file system on restoration. Backing up the database first ensures that you capture any new files that are added during the backup process.

Files are written one time only so that their identities are obvious if a file is missing during a restore.
You must prevent any file-deletion tasks from running during an online backup. When a user deletes a file, the file is removed from the user interface and added to a queue of files to be deleted from the file system. This deletion task runs regularly to delete the first item from the queue. You can increase the time that files can remain in the queue before they are deleted. Increase this time by adjusting the value in the scheduledTasks.FileActuallyDelete.args.softDeleteMinimumPendingTimeInMins property in the wikis-config.xml file. Increasing this time interval can give you enough time to run incremental backups to ensure that your archive is complete.
