Tape data sets listed with this optional keyword physically accompany the control and data files from the aggregate backup site to the aggregate recovery site and are cataloged as part of an aggregate recovery. These data sets are not written to the data file. You must provide your own copy of the data set to be used at the aggregate recovery site.
Example: You can have a large tape data set that would take too much time to copy to the data file. If you can specify this data set in the ACCOMPANY list, and the data set is cataloged at the aggregate recovery site. Then you must transport the tape containing the data set to the aggregate recovery site.
The ACCOMPANY keyword syntax is:
| Keyword | Field |
|---|---|
| ACCOMPANY | (dsn..., dsnmask...) |
