Maintenance Commands
BACKUP Command
The BACKUP command writes the Audit Trail file to the tape mounted on the
drive assigned to logical unit SYSnnn.
The format of the command is shown below.
BACKUP [ ADD [INPUT=SYSnnn] [TAPE=SYSnnn] ]
[ ]
[ INITIALIZE [DISP=KEEP] [TAPE=SYSnnn] ]
ADD
Required if using other optional parameters. Copies the period-to-date audit
information from the input (previous period-to-date tape) to the output tape
and adds new information.
ADD is the default if only BACKUP is specified.
INITIALIZE
INPUT=SYSnnn
Required if using other optional parameters. Initializes tape for output. The
Audit Trail data is written at the beginning of the tape.
Optional parameter. If ADD is used, the input tape is assigned by logical unit
SYSnnn (default is SYS005.)
Note: ADD and INITIALIZE are mutually exclusive.
TAPE=SYSnnn
DISP=KEEP
Optional parameter. Assigns the output tape by logical unit SYSnnn (default is
SYS006).
Optional parameter. Ensures that the Audit Trail file is not cleared after the
BACKUP function is run. This operand is only valid on a BACKUP INITIALIZE
command. Use DISP=KEEP only for generating tapes for reporting and testing.
This reduces the possibility of creating multiple copies of the same data.
Examples
BACKUP INITIALIZE DISP=KEEP
BACKUP INITIALIZE TAPE=SYS008
BACKUP ADD INPUT=SYS010 TAPE=SYS011
