Control file
The control file is the output data set tape file created by aggregate
backup that is used later as input to an aggregate recovery. It contains
control information necessary to recover the data sets, defined to
the aggregate.
Note: The control file can reside on 1 to
15 volumes. If the 15-volume limit is exceeded, aggregate backup fails.
If this occurs, either use tapes with a higher density to contain
the control file or define multiple aggregate groups for the application
so that each aggregate backup does not back up such a large amount
of data. Reissue the ABACKUP command.
The format of the control file name is outputdatasetprefix.C.CnnVnnnn. This is the same outputdatasetprefix you previously specified in the aggregate group.
The name of the control file in the example is PAY1.C.C01V0001. The data set PAY2.PY001.BENEFIT is identified on the control file to be allocated at the aggregate recovery site. The data set PAY2.PY001.TAXES is identified on the control file to be cataloged at the aggregate recovery site.
