Hello Rakeshkonjengba
The scope depends on the type of repository and of the pupose of the backup
To transfert customizations of a system database (systemdb), it is recommended to backup extensions only (metamodel layer and technical level layer, no data)
Example (VB script)
MySystemDb.LogicalSave "C:\temp\test_logicalbackup.mgr","Meta=On,Technical=On,Data=Off"
To transfer data of a data repository, it is recommended to backup all data (no, metamodel layer, no technical level layer, data full)
Example (VB script)
MyDb.LogicalSave "C:\temp\test_logicalbackup.mgr","Meta=Off,Technical=Off,Data=Full"
More details on API function in the API documentation in javadoc format. See this KB
