SPHERE is an optional parameter that can be specified with NEWNAME. If YES is specified a backup of the entire VSAM SPHERE will be performed. If NO is specified, a backup of the base cluster will be performed, and any associated AIXs and/or PATHs will not be backed up. If SPHERE is specified without a parameter, or if SPHERE is not specified at all, DFSMShsm will attempt to back up the entire SPHERE. If SPHERE is specified without NEWNAME, the HBACKDS command will fail. The default is YES.
