An aggregate group is an SMS construct
that uses control information
and data set lists to define an application or other group. The data
stored in the aggregate group is the principal input to DFSMShsm application
backup and recovery.
An aggregate group consists of backup criteria
and a group of data
sets selected for backup by the storage administrator according to
application or other requirements. See z/OS DFSMShsm Storage Administration for
further information on backing up or recovering aggregate groups.
The
aggregate group application allows you to:
- Generate a list of aggregate groups
- Display the attributes
of a single aggregate group
- Define or alter the attributes
of a single aggregate group
- Delete aggregate groups
- Edit
and browse the selection data sets associated with aggregate
groups
- Edit and browse the instruction data sets associated
with aggregate
groups
- Back up the selected aggregate group
- Recover
an aggregate group that has already been backed up
- Specify
one to fifteen local copies of aggregate backup (ABACKUP)
output files to be created
- Assign aggregate backup attributes
to an aggregate group by specifying
a management class name
Restriction: You
cannot
assign an object to an aggregate group.
ABACKUP allows specifying
the number of copies of the Aggregate
Backup and Recovery Support (ABARS) output files to be created using
ISMF. The Copies value can be 1-15. The default is 1.
In order
to support the creation of multiple copies, a unique name
must be created for each copy. This entails using a new suffix convention
for the output data sets:
- .D.CccVnnnn for the DFSMSdss data file
- .O.CccVnnnn
for the internal data file
- .C.CccVnnnn for the control file
- .I.CccVnnnn for the instruction or activity log file
where
- cc
- Represents the copy number (a number from
1-15 of the copy created)
- nnnn
- Represents
the version number
The name supports the elimination
of the GDG support.
