Hi Kamalakar,
Looks to be the following
https://tools.cisco.com/bugsearch/bug/CSCur24834/?reffering_site=dumpcr
Symptom:
UCCX backup fails on CUIC component for second node (phx_config)
Conditions:
UCCX 10.5 SU1 HA
Workaround:
1. Enable Root access on both first node and the second node
2. Copy the /opt/cisco/desktop/openfire/passphrase from Primary Node to the same location on Secondary Node.
3. Restart the Unified CCX Notification Service and the Cisco Finesse Tomcat service.
4. Redo the Back up. It should work this time.
HTH
