To back up an embedded database, run the zman qa -t "pgsql.maintenance.queue" -d "{"backupParams":{"backupDir":"/var/opt/microfocus/zenworks/common","backupZen":true,"backupAudit":false},"vacuumParams":{"vacuumZen":false,"vacuumAudit":false}}" command on the server that has the database role.
In the above command, depending on which database you want to backup change the parameter to true or false.
