Reply from jack_nsk on Nov 13 at 11:56 PM I do system copy using online backup and forwards recovery as described at note "SAP Note 1003028 - Enhanced support for database copy in BR*Tools". But this note is intended for Oracle. I think there is something for MS SQL

Subject: Simultaneous System Copy of ERP and SRM
Hi all,
I am using SAP ECC6 ERP 6 with EHP6 with Netweaver 7.31 on MS Windows 2008 R2 with DB MS SQL 2008 R2. I do system copy from Production ERP to Quality ERP 4 times an year and to other sandpit systems after every month.
Now as we have implemented SRM system (Netweaver 7.31 SRM 7.02) and the SRM system is connected with ERP system, I am facing some issues in system copies.
My scenario that, if I start backup for ERP and SRM even simultaneously, the SRM backup finishes in 20 minutes while ERP backup takes around an hour. It means during the backup of ERP system when the backup of SRM is finished, there is a lot of chances that data will updated in SRM system and as a result also changed in ERP system and that change will go in the ERP backup which is not in the backup of SRM. Therefore there are some inconsistent data (or orphan data) in ERP.
After completion of system copy the data in ERP will be more as compare to SRM. If we run some reports we'll found the inconsistency.
I understand that one method to take backup of both systems and then apply transaction logs to achieve the point in time backup.
Can anybody help me with any other process withing SAP boundaries? I am afraid that after some months our BW system will also be operational and we have to do simultaneous system copy of PRD(ERP+SRM+BW) in QAS(ERP+SRM+BW)!!!!!!!!!!!!!
Appreciate in advance for any help and suggestion
Regards,
