Policy automatically started without related schedule time?

what is the time zone/region setting on your server? Does it match with where you are?

Timezone is the first I would check, but if it isn't, check admin log or run nbauditreport to see if anyone has manually started it...

the timezone is ok, I have other policies in place and all of them start as expected.

Nobody could have manually run it, I'm the only one here with access to the server and with admin rights.

Can you show us the tabs of the job itself (screen shots) as they will say either scheduled or immediate

Could we also see bppllist policyname -U so that we can see the exact configuration

Thanks

Here you are the screenshots of the policy

You forgot to provide the job details (overview & details) screenshot as requested by Mark... 

The Overview tab of the SQL job will tell us if job ran 'scheduled' or 'immediate'.

It's been 4 days since your original post - if you have not checked yet, chances are that job is already removed from Activity Monitor (default is 3 days).

Sorry, you are right I forgot it, here you are the overview, as you can see is "scheduled" :

In the detail there is nothing interesting, I just paste the first rows where something about schedule appears:

20/06/2014 18.00.00 - Info nbjm(pid=360) starting backup job (jobid=3940) for client xxxxxxx, policy SQL_1_FULL, schedule Full  
20/06/2014 18.00.00 - Info nbjm(pid=360) requesting MEDIA_SERVER_WITH_ATTRIBUTES resources from RB for backup job (jobid=3940, request id:{DC698C72-FEBD-4196-B764-92DD30FBB93B})  
20/06/2014 18.00.00 - requesting resource MSL4048_FC
 

thanks
