The SAP backup library helps to optimize the utilization of quick tape drives by combining multiple data files in savesets. Multiple file access (file multiplexing) maximizes the flow of data (streaming mode).

The command option is brbackup -s|-savesets .

A saveset can contain individual data files, all files of a tablespace, or the complete data backup. The size of the savesets for the backup must be selected according to the tape device. A fast data flow with a minimum saveset size is the optimum.

Large savesets are not recommended, since in a restoration the complete saveset has to be imported, even if only one data file is required.

saveset_members = all is set as standard for an incremental backup with the SAP backup library so that only one "incremental saveset" is created including all changed blocks.
