You can use ISMF to define,
alter, list, display, back up or recover
an aggregate group, or edit the selection or instruction data sets
associated with an aggregate group by selecting option 9, Aggregate
Group, from the ISMF Primary Option Menu for Storage Administrators.
A selection data set is a data set which contains lists of data sets
to be included in the backup of an application or other group. An
instruction data set is a data set which contains instructions, commands,
and so on, that are copied into the control file volume after the
backup control file.

groups. See the following
