SAP Note 27766 - Separate Backup of client or development class

Symptom:

How do you do a database backup of
a) an individual client
b) an individual development class

Cause and prerequisites

Only one part of the system data is important, and must be saved.

Solution
The database may only be saved in its entirety. It is indeed technically possible to save and reimport individual tables with the database resources, but consistency is no longer ensured after this.
The export of a client or a development class using the R/3 transport system is technically and logically possible (client: RSCLIEXP; Development class: SE02 -> "Utilities" -> "DevClass commfile").
The files generated in this way can be saved with the normal operating system resources. However, this is not a procedure recommended by SAP: The export of large datasets can cause considerable performance losses and transport is not provided for data backup. The only standard way to do this is via a complete database backup (see customer letter 12/95).
