#1 Restoring image from DVD
Hi there,
I've tried several free ghosting software and found a
liking to g4u and g4l, and I sattled for g4l because
g4u doesn't support my network card.
Anyway, I now have a image of my laptop sitting on my
FTP server, and it's all fine and dandy - except from
one part: I'd like to have the image with me on-the-go
so I can restore my laptop while I am on the road.
"Easy", you say, "just burn the image to a CD/DVD and
use 'dd' to restore it from there". "Sure", I say,
"except from one tiny problem: the image doesn't fit on
a single DVD".
So here's my problem: how can I write a restore process
that allows me to have the image splitted on several
media's?
Best regards
Michael Boman
PS
I find the dialog interface cumbersome so I issue the
relivant commands on the command line directly. It
would be nice if a command line version would be
available, just like g4u has it.

A couple issues. First, restore from a DVD would be easy if
you could copy a single image file to the DVD. It would only
require booting the G4l, and then use the local option to
mount the DVD and then copy the image. Problem is that the
image file may be larger than will fit on 1 DVD. A better
solutions would be to have a USB hard drive that could store
the whole image. Again using the local copy option.
Another options would be to reduce the size of you
partitions on the current hard drive, and create the image
on the extra space. Say if you had an 80gb hard drive, setup
20gb as a linux ext2 partion. Then use g4l to create an
image on that partition. This wouldn't help with a hard disk
crash, but would allow for a restore if the current
partitions got corrupted.
Not sure which version of g4l you are using, but the latest
versions I have on the freshmeat site include the options to
set most parameters.
./g4l ftpserver filename.ext '-u user -p password' dhcp
That would default the ftpserver, filename, ncftp
user/password, and use dhcpd to get the ip address. You
would then only need to press the enter key up to the point
of selecting backup or restore. If the extention is gz or
lzo then it will use the correct compression, with bzip, you
will need to change the compression. I like the lzo since in
my environment, it is about twice the speed of gzip with
only a 15% increase in size. bzip was just taking to long,
so I don't know how much longer it would have taken or how
much smaller the image might have been.

Many updates in version 0.15 and 0.16 to allow for command
line options to the script and showing defaults. Problem
with burning directly to a dvd, and problam of spanning disk
if image larger than 1 disk. Currently the splitting can be
done to the hard drive, but then restoring from a DVD would
be a problem. Might be possible, but at this point, not
something I am able to do.
