NBU8 error unimplemented error code (114)

I found the backup failed with unimplemented error code  (114).

Env:

1. NBU 8.0 master is appliance

2. Backup to SQL 2012 Server with Windows 2012R2  -> this server is Virtual machine on VMware 5.5

Symptom:

1. Backup SQL intelligent policy ->  pass

2. Backup VM policy with GRT SQL  -> failed 

3. Backup VM policy with no GRT SQL -> pass

-----------------------------------------------------

Error: (2. Backup VM policy with GRT SQL)
