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.
