Use this command to create a backup of the IBM InfoSphere CDC metadata database which contains information about your current replication configuration. You should always back up your metadata when there are changes to your subscription configuration and table status. You can only back up your metadata while IBM InfoSphere CDC is running.
The backup of the metadata database is created in <Installation_directory>/ instance/<instance_name>/conf/backup for UNIX and Linux and in <Installation_directory>\instance\<instance_name>\conf\backup for Windows. The files in the backup directory should be stored on separate media for possible recovery.
