BIG-IQ 5.3 backup issue on secondary HA node

Hi,

 

Since I did the BIG-IQ upgrade from release 5.1 to 5.3 on our HA running as virtual installation the backup on the secondary node fails with the error „Cannot create or restore backup on a BIG-IQ HA secondary“.

 

For test purposes I promoted the secondary node to primary end executed the backup again. This time the backup run on the previous secondary node which became a primary and failed on the current secondary. The devices are synced regularly without any issue. Has anybody similar issue after upgrade?
