Backup Sap with multiple retantions

[luca72m]

Hi,

i have several policies witch backup files of SAP istances.

I using old custom scripts with tsm.

Three scripts, the first initialize the backup, the second selects the correct file. utl depending on the day, the third run the backup command.

I want to delete the script and use the script native NBU (C:\Programmi\VERITAS\NetBackup\DbExt\SAP\samples)

How do I create a single policy that through the application schedules make me 4 types of retention (daily, weekly, monthly and annual)

Example:

policy.sap.online

sch.aut    schedule the script

sch.app.day     save the file with retantion 15 day

sch.app.wee    save the file with retantion 30 day

sch.app.mon   save the file with retantion 12 months

ecc .....

thanks a lot

Hi,

NetBackup can't do this for Database Agent backups. I have however found a way to trick it, you can check the post below for more details. Little tricky and could be dangerous if not monitored correctly......

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.

Thank for the reply.

The best solution for my case is that of Oddy.

I delete the application schedule under SAP.UTL file and setting the correctly haurs for the application.

So i use only script for all retention. I try to do this and after i write my experience.

Thanks at all.

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.
