Also you could make the backup in tree steps:
1) zVM backup (system packs only): there are the mdisks 123, 124, 125 that are the xxxres, xxxw01, xxxw02, etc, dasds accessed r/o. So, with the system running you can make a ddr from those MAINT minidisks to tapes.
Also you should not forget to make the spxtape of system spool data files, this is very important. You need to do this only after the instalation of the system and when you apply RSU or some system PTFs.
2) Backup of z/VM user data: like users minidisks and users spool files. Use spxtape (for spool) and DDR (for files and minidisks or dasds) for this.
3) Backup of Linux systems and data: for this you could use any Linux tools (like tar) or an application program for backup, like TSM (Tivoli Storage Manager), etc. Or you could do a full backup using DDR of the Linux dasds or minidisks.
Anybody want to add anything?

I think you are asking how to backup the VM system. Use DDR to back up all DASD to tape, be sure to do all cylinders (0-END) and you should shutdown your Linux guests and all non-essential services while backing up to ensure data integrity.
For example, to backup real device A00:
CP ATTACH A00 * (Or link to fullpack minidisk, can be R/O) CP ATTACH xxx * 181 (where XXX is a real tape drive) DDR SYS CONS IN A00 DASD SCRATCH OUT 181 TAPE (COMPACT DUMP ALL
Repeat for each DASD device you use.
That ought to do it. You should also have a stand alone DDR tape handy in case you need it.
