There is another alternative, use a commerical program like CTar.
It is more in-depth program than tar, and backs up ALL the files and
directories of a system (including device drivers, char files, zero dirs,
and sorts of other interesting items)..
CTAR also comes with a utility program to create a rootable/bootable
diskette with all the necessary utilities and even a menu front-end to
make disaster recovery much easier. (especially at 3am, when your eyes
don't work so well).

You can create all of the above yourself, or use CTAR to do all the work
for you, and not have to worry about (did I get ALL the programs I wil
need in a disaster on my recovery diskette).

CTAR also includes scripts to automatically create an entry in cron
for automated backups at whatever time is appropriate, will auto-
failure scripts to do whatever you want if the backup fails.

In other words, you can fish thru the manuals and create everything yourself
if you have the inclination, or a commercial program to do all of the work
for you.  We have been using Ctar for several years now on all of our
client's machines and have been very impressed.    We are not affiliated
with Microlite (CTAR) other than a satisfied user.
