Backing Up Your System and Software
The most important part of your system is the data you have accumulated. It
is also especially important to protect your system in general from corruption if
your HP-UX has been supplied as a pre-installed \Instant Ignition" disk. You
can protect your data and system from loss, using the general procedures given
in this chapter. (For detailed procedures, see
9.0 and System Administration Tasks .)
Make sure you create and maintain a backup HP-UX kernel (
on your disk from which you can boot in an emergency. A
automatically created by SAM whenever you recon gure and reboot a new
kernel from your system console.

Cartridge tape drives.
DDS-Format (similar to \DAT") drives. (See warnings regarding using
DAT tape in \Con guring for a DDS Tape Drive" in Chapter 5).
Magneto-optical disk drives.
Other hard disk drives.

recovery system is created by using commands rather than by using SAM.
You can also restore your system from a system CD ROM that you can
purchase from your HP sales representative.
