The BACKUP Data Area option of DBUTLTY reads the specified area (or all areas of a database for a "base-level backup") and writes a sequential output data set. A backup can also be made of a data area that either INCLUDEs or EXCLUDEs specific tables. The output data set record format is variable blocked.
Note: Since a MRDF-supported virtual area exists only in the Multi-User Facility memory, you cannot perform a backup of the data without MULTUSE=YES. If you execute the backup of a virtual table without MULTUSE=YES, the backup accesses the disk area either unloading no records or unloading any records as they existed in the area before it became virtual. You can perform a backup of a covered area since CA Datacom/DB writes to both the area in memory and the DASD copy.
