    I finished and tested the scripts.

    I solved my problem in this way:

    • 4 Configuration Files .SAP

    and

    • 4 Configuration Files .Utl

     

    • initSID.nbu_weekly.sap  initSID.nbu_weekly.utl
    • initSID.nbu_monthly.sap  initSID.nbu_yearly.utl

     

    • initSIDnbu_daily.sap  initSID.nbu_monthly.utl
    • initSIDnbu_yearly.sap  initSID.nbu_daily.utl


    I select the files to be associated with backup command using the environment variable

     

    %SAP_SNC_SCHED%

     

    With the correctly file .SAP invokes the application scheduler by means of utl file which is set in the file .sap

    To follow there are two scripts, one for windows one for unix.

Hi,

I would recommend you to create one sap policy and configure the init<sid>.utl file to specify the policy but not the schedule, you can hash it out.

In the sap policy reate a full automatic schedule and an application backup schedule for the daily backup and open the backup window for the time you want it to run. I.e mon-fri from 8PM to 11PM. Set retention to 15 days for the application backup schedule.

Create a new full automatic schedule and an application backup schedule for the weekly backup and open the backup window when you want this to run, I.e Sun 8PM 11PM and set retention for this application backup to 30 days.

Create a new full automatic and application schedule for the monthly backup and open the backup window when you want this to run. I.e last Saturday in every month at 1AM- 3AM and change the retention period for the application backup to 12 months.

Do the same for the annual backup and open the backup window at a time when no other backup windows is opened in the policy.

You might have to tweek this and find your best timing to do this. You only want one application backup schedule open in the policy at the time the backup is running with the correct retention.

I hope this helps.
