Reducing the size of the *DBXREF files will not reduce storage requirements on tape\backups, only reduce the storage on disk\DASD.

That is because the Save System (SAVSYS) does *not* include the data [from all but one, typically the smallest] of those files QADB* in QSYS; neither the physical data nor the access paths of all but the QADBXRDBD files are ever saved.

To reduce the size of storage in the SAVSYS, delete any unneeded History files (QHST*) and reduce the private authorities; private authorities can be moved to Authorization Lists (*AUTL), but as consolidated authorities, they will take significantly less storage.
