SAP system copy : Backup Restore

Today, we got job from our project manager to set up system like a real production for testing purpose, because we use UNIX for our SAP Landscape, we decide to set our sandbox system (like production) use Backup restore method, we think it's better idea because we have tight timeline.

we already have SAP ECC6 EHP 6 SP 6 for our landscape, we need to patch our SAP_HR for the latest one, of cource we have to need sandbox system for testing only by ABAPer and Functional team.

so, we need setup sandbox system, fisrt let me describe what we do until finish :

1. We need Server installed with same OS version like our real production, we use AIX 6.1 TL2
2. make sure all software patch same with existing server like C++ librabry, Bor.rte, etc
3. We only need backup online + Redolog offline for yesterday
4. we need copy Oracle engine, SAP Kernel, Oracle client and SAP System Administrator environment
5. We copy all services (/etc/services)
6. Restore backup online
7. Restore Redo log
8. Apply Redo log
9. We open database and Start SAP

we prepare for this action only 1 day which is

1. backup online + redolog we did day before
2. FTP of backup online + redolog we did day before
3. Copy All engine --> 3 Hours
4. Precheck all prerequisites before start SAP & oracle 1 Hours
5. restore from hot backup, we need only 1 hours (DB Size +/- 400 GB), we use compress = yes
6. recovery database from offline redolog after restore
7. Open database and SAP started.

So, we have clone of SAP Production and start to patch our SAP_HR, EA-HR

Cheers..
