HI René,
I believe there is a little misunderstanding. To perform a system copy, there are 2 methods:
- Database Specific method (this involves backup and restore of the database) - see chapter 5 from the guide
- Database Independent method(this involves export and import of the database) - see chapter 4 from the guide
If you select method #1, you must backup the entire database of the source system. Since in NW release 7.01 there are some Java application information at file system level, it's also required to perform an export of this data. So, the export in this case will only export SDM and Application specific data.
In method #2, there is no backup needed. SAPinst will export the entire database of the source system and this data will be imported into the target one.
Regardless of the method you choose, both stacks must be copied at once.
Regards,
Alessandro
