Question on dump and OS backups

Question on dump and OS backups

Post by Pet » Sat, 02 Jan 1999 04:00:00

Considering the fact that my kernel rebuilds have been disasters and I'm
tired of installing linux, I'd like to make sure I know how to use dump
and restore correctly.

To backup the root partition to a file /usr/backup/hda1file (which is on
partition /dev/hda1), is this correct:

dump 0f /usr/backup/hda1file /dev/hda1

and to restore:

restore rf /usr/backup/hda1file

Will this completely erase the root partition (with the trashed kernel) and
restore an exact copy of the partition at the time of the dump?

I have a book that says you run into trouble when you try to restore the
file 'restore'; you can't restore the restore command.  Has anyone run into
this before?   What is the workaround to this problem if it really exists?


ps- If I were to purchase a tape backup system, can someone recommend a
linux friendly product?  Ease of installation/usage is infinitely more
important than speed.

I can't answere your backup question, but I remember forgetting to add
something to my post to your other question.

It is possible to have multiple boot images for Linux.  I always make
sure I keep a spare in case I*up a build.  In fact, I also keep
the original canned kernel that I installed.  Lilo uses /etc/lilo.conf
to decide which image to boot into.  This is my lilo.conf file.
Please don't ask me about the file format.  All I did was add two
sections for my other boot images.

# LILO Konfigurations-Datei
# Start LILO global Section
#compact        # faster, but won't work on all systems.
vga = normal    # force sane state
# End LILO global section
# Linux bootable partition config begins

# primary boot image
image = /vmlinuz
root = /dev/hda3
label = Solo

# canned boot image
image = /vmlinuz.can
root = /dev/hda3
label = canned

# previous boot image
image = /vmlinuz.old
root = /dev/hda3
label = prev

# Linux bootable partition config ends

1. dumping one Mac OS hd to another a la dump/restore

I have a second hand Mac which has a small HD with some very cool sw
which I want to keep, but it physically takes space in my 7500 box.
Is there any way to dump and restore the small disk in a larger one
using just Mac OS functionality (I need this so that I can install linux
on a third HD which is sitting on my desk :-( ) ?
